Frequently Asked Questions - Optimate DCDC Tecmate

What types of batteries can I charge with the Optimate DCDC?

The Optimate DCDC automatically charges 12V lead-acid batteries (STD, AGM, GEL, AGM cyclic) and 12.8V lithium LiFePO4 batteries. Do not use for dry cells or frozen batteries.

How to connect the charger to a battery installed in a vehicle?

First, connect the positive clip (red) to the positive terminal not grounded. Then, connect the negative clip (black) to the chassis away from the battery. Disconnect in reverse order. Check polarity before connection.

What does the flashing of LED #5 mean?

LED #5 flashes during the voltage retention test. A single flash indicates a good lead-acid battery, a double flash indicates a good lithium battery.

How long does it take to charge a battery?

Charging time is approximately half the capacity in Ah. For example, a 10Ah battery takes about 5 hours to reach step 4. Deeply discharged batteries may take longer.

What to do if LED #6 red lights up?

Red LED #6 indicates a problem: defective battery, sulfated, or current loss in the circuit. Check the battery and connections. If the battery does not maintain 12.4V after charging, it is likely unusable.

Can I leave the charger plugged in permanently?

Yes, the Optimate DCDC can remain connected for long-term maintenance. It monitors and recharges the battery automatically. Check connections every 15 days and electrolyte level for batteries with caps.

How to recover a deeply discharged battery?

Connect the charger to a source battery (12V). If the battery has at least 1V, LED #3 lights up for recovery. First a low current (200mA) up to 8.8V, then pulses up to 2A. If the battery does not hold the charge, it is irrecoverable.

What is the power consumption from the source battery in maintenance mode?

Consumption depends on the current drawn by the vehicle. For example, a drain of 10mA consumes 0.3Ah per day. A 27Ah source battery can thus supply the circuit for about 90 days.

Can I use a mains power supply instead of a source battery?

Yes, you can use a DC 12-16V adapter with a current of at least 3A. Connect it to the DC IN input. The device works the same as with a source battery.

What to do if the input cable is damaged?

The input cable must be replaced by the manufacturer, an authorized agent, or a qualified workshop to avoid any danger. Do not use the charger with a damaged cable.

f) Be extra cautious to reduce risk of dropping a metal tool onto battery. It might spark or short-circuit battery or other electrical part that may cause explosion.
g) Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a lead-acid battery. A lead-acid battery can produce a short-circuit current high enough to weld a ring or the like to metal, causing a severe burn.
i) NEVER charge a frozen battery.

12. PREPARING TO CHARGE

a) If necessary to remove battery from vehicle to charge, always remove grounded terminal from battery first. Make sure all accessories in the vehicle are off, so as not to cause an arc.
b) Be sure area around battery is well ventilated while battery is being charged. Gas can be forcefully blown away by using a piece of cardboard or other non-metallic material as a fan.
c) Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes.
d) Add distilled water in each cell until battery acid reaches level specified by battery manufacturer. This helps purge excessive gas from cells. Do not overfill. For a battery without cell caps, such as valve regulated lead acid (VRLA) or absorbed glass mat (AGM) batteries, carefully follow manufacturer's recharging instructions.
e) Study all battery manufacturer's specific precautions such as removing or not removing cell caps while charging and recommended rates of charge.
f) Determine voltage of battery by referring to vehicle or other user's manual and BEFORE MAKING THE BATTERY CONNECTIONS, MAKE SURE TH AT THE VOLTAGE OF THE BATTERY YOU ARE GOING TO CHARGE MATCHES THE OUTPUT VOLTAGE OF THE CHARGER.
13. CHARGER LOCATION.
a) Locate charger as far away from battery as DC cables permit.
b) Never place charger directly above battery being charged; gases from battery will corrode and damage the charger. c) Never allow battery acid to drip on charger when reading gravity or filling battery. Do not operate charger in a closed-in area or restrict ventilation in any way.
d) Do not set a battery on top of charger. IMPORTANT : Place charger on a hard flat surface or mount onto a vertical surface. Do not place on plastic, leather or textile surface.

14. DC CONNECTION PRECAUTIONS

a) Connect and disconnect DC output clips only after setting any charger switches to off position and removing DC cord from supply. Never allow clips to touch each other, however should this happen no damage will result to the charger circuit & the automatic charging programme will just reset to «start».

b) Attach clips to battery and chassis as indicated in 15(e), 15(f), and 16(b) through 16(d).

NOTE : This battery charger has an automatic safety feature that will prevent it from operating if the battery has been inversely connected.

IMPORTANT: READ THE FOLLOWING INSTRUCTIONS BEFORE USING THE CHARGER This appliance can be used by children aged from 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning use of the appliance in a safe way and understand the hazards involved. Children shall not play with the appliance. Cleaning and user maintenance shall not be made by children without supervision.

SAFETY WARNING AND NOTES: Batteries emit EXPLOSIVE GASES - prevent flame or sparks near batteries. Disconnect DC input supply before making or breaking DC/battery connections. Battery acid is highly corrosive. Wear protective clothing and eyewear and avoid contact. In case of accidental contact, wash immediately with soap and water. Check that the battery posts are not loose; if so, have the battery professionally assessed. If the battery posts are corroded, clean with a copper wire brush; if greasy or dirty clean with a rag damped in detergent. Use the charger only if the input and output leads and connectors are in good, undamaged condition. If the input cable is damaged, it is essential to have it replaced without delay by the manufacturer, his authorised service agent or a qualified workshop, to avoid danger. Protect your charger from acid and acid fumes and from damp and humid conditions both during use and in storage. Damage resulting from corrosion, oxidation or internal electrical short-circuiting is not covered by warranty. Distance the charger from the battery during charging to avoid contamination by or exposure to acid or acidic vapours. If using it in the horizontal orientation, place the charger on a hard, flat surface, but NOT on plastic, textile or leather. Use the fixing holes provided in the enclosure base to attach the charger to any convenient, sound vertical surface.

EXPOSURE TO LIQUIDS: This charger is designed to withstand exposure to liquids accidentally spilled or splashed onto the casing from above, or to light rainfall. Prolonged exposure to falling rain is inadvisable and longer service life will be obtained by minimizing such exposure. Failure of the charger due to oxidation resulting from the eventual penetration of liquid into the electronic components, connectors or plugs, is not covered by warranty.

BATTERY CONNECTIONS: INPUT: A set of fused battery clips is supplied. OUTPUT: 2 interchangeable connection sets are available, supplied with the charger is a set of battery clips for charging the battery off-vehicle, the other connection set comes with metal eyelet lugs for permanent connection to the battery posts, and re-sealable weatherproof cap on the connector that connects to the charger output cable. This connection set allows easy and sure connection of the charger to maintain the battery on-vehicle. The resealable weatherproof cap is designed to protect the connector from dirt and damp whenever the charger is not attached. Consult a professional service agent for assistance in attaching the metal eyelets to the battery posts. Secure the connector with weatherproof cap so that it cannot foul any moving part of the vehicle or the cable can be pinched or damaged by sharp edges. The in-line fuse in the eyelets connection set protects the battery against such accidental shorting across positive and negative conductors. Replace any burnt fuse only with a similar new fuse of 15A rating.

CONNECTING THE CHARGER TO THE BATTERY

1. Disconnect SOURCE BATTERY before making or breaking DC / battery connections of battery under charge.
2. If charging a battery in the vehicle with the battery clips, before making connections, first check that the battery clips can be safely and securely positioned clear from surrounding wiring, metal tubing or the chassis. Make connections in the following order: First connect to the battery terminal not connected to the chassis (normally positive), then connect the other battery clip (normally negative) to the chassis well away from the battery and fuel line. Always disconnect in reverse sequence.

3. When charging a battery out of the vehicle with the battery clips, place it in a well ventilated area. Connect the charger to the battery: RED clamp to POSITIVE (POS, P or +) terminal and BLACK clamp to NEGATIVE (NEG, N or -) terminal. Make sure the connections are firm and secure. Good contact is important.

4. If the battery is deeply discharged (and possibly sulphated), remove from the vehicle and inspect the battery before connecting the charger for a recovery attempt. Visually check the battery for mechanical defects such as a bulging or cracked casing, or signs of electrolyte leakage. If the battery has filler caps and the plates within the cells can be seen from the outside, examine the battery carefully to try to determine if any cells seem different to the others (for example, with white matter between the plates, plates touching). If mechanical defects are apparent do not attempt to charge the battery, have the battery professionally assessed. CHARGING: For safety reasons, the OptiMate output will only activate if a battery retaining at least 1V is connected. A battery left deep-discharged for an extended period may develop permanent damage in one or more cells. Such batteries may heat up excessively during high current charging. Monitor the battery temperature during the first hour, then hourly there-after. Check for unusual signs, such as bubbling or leaking electrolyte, heightened activity in one cell compared to others, or hissing sounds. If at any time the battery is uncomfortably hot to touch or you notice any unusual signs, DISCONNECT THE CHARGER IMMEDIATELY.

5. If the battery is new, before connecting the charger read the battery manufacturer's safety and operational instructions carefully. If applicable, carefully and exactly follow acid filling instructions.

USING THE OPTIMATE DC-DC: PROCEEDING TO CHARGE

CONNECTING THE CHARGER TO A DC SUPPLY (DC adapter rated at minimum 15V 3A or a fully charged 12V battery): When the OptiMate DC-DC 12V 2A is connected to a SOURCE BATTERY or DC supply measuring at least 12V (range: 12-16V) LED #3 and 4# will flash twice and then continue to slowly flash for one minute to indicate it is ready for a battery requiring charge & maintenance to be connected. If a battery is not connected the charger shuts off completely. The charger will activate if connected to a recipient battery measuring 10V or more OR to reset the charger: 1) disconnect from source battery, 2) connect to the battery to be charged, 3) re-connect to the SOURCE BATTERY or DC supply.

SOURCE BATTERY: Source battery capacity (in Ah) should ideally be 1.5 times higher than the battery to be charged. E.G. to recharge a flat 10Ah battery, you need a 15Ah source battery. The 12V SOURCE BATTERY should ideally be rated for deep cycle use.

POWER CONSUMPTION FROM SOURCE BATTERY WHEN MAINTAINING A VEHICLE BATTERY: The power consumption depends on the current demand of vehicle / electronic circuitry from the battery to be maintained. As an easy reference: For every 10mA of drain current by vehicle / connected circuitry, assume a drain of 0.30Ah per day (24 hours) from the source battery. E.G. Source battery min. capacity for a 90 day period if current drain from vehicle battery is 10mA : 0.3Ah x 90 = 27Ah.

CHARGING TIME: The time required for the OptiMate DC-DC 12V 2A to complete a charge on a flat but otherwise undamaged battery is roughly equal to 1/2 the battery's Ah rating, so a 10Ah battery should take no more than about 5 hours to progress to Step 4. Deep-discharged batteries may take significantly longer.

The LED indicators referred to below, and the clauses dealing with them, are sequenced as they may come on through the course of the program.

graph TD
    A["1: DC IN"] --> B["2: AC"]
    B --> C["6: TEST MAINTAIN"]
    C --> D["3: SAVE"]
    D --> E["4: CHARGE"]
    E --> F["↓"]

1. LED #1 - Lights to warn the SOURCE BATTERY voltage has reduced below 12V (low charge level). Recharge and reconnect for further maintenance. Once the SOURCE BATTERY voltage reduces below 11V OptiMate DC-DC 12V 2A will shut off to avoid deep discharging the SOURCE BATTERY.

2. LED #2 indicates inverse polarity - wrong output connections. Swap around to activate output.

3. LED #3 SAVE lights If the battery is extremely flat (deep-discharged or sulphated), Time: 4 hours.

3.1 LOW VOLT SAVE (from 2V) to 8.8V (LED #3 steady on): Current is limited to 200mA so that the battery may gently recover to a safe voltage level of 8.8 Volts. Batteries able to accept 0.2A of charge current will advance to PULSE recovery.

3.2 PULSE recovery - LED #3 steady on: Current up to 2A is delivered in pulses to prepare the battery to accept normal charge. This mode is particularly effective for recovery of factory activated / "hi-performance" pure lead or cyclic cell AGM batteries

4. LED #4 Charge and charge verification

4.1 CHARGE: The BULK CHARGE stage delivers a constant current of about 2 Amps into the battery, up to a voltage of 14.2 -14.5V.
4.2 Optimize / Pulsed absorption: Engages when the voltage has reached 14.3V for the first time during CHARGE mode. Current is delivered in pulses, varying between 0.2 and 2A and up to a voltage of 14.2 - 14.4V, to bring the battery to full charge in the shortest possible time. Charge time is usually extended if there is higher than expected current draw by connected circuitry or battery health is less than optimal.

NOTE: For safety reasons there is an overall charge time limit of 48 hours.

5. VOLTAGE RETENTION TEST: LED #5 flashes every 3 seconds

(single flash = good lead-acid battery, double flash = good lithium battery)

Delivery of current to the battery is interrupted for 30 minutes to allow the program to determine the battery's ability to retain charge. For batteries with a good state of health LED #5 (green) should continue to flash for the full 30 minute period (single flash = good lead-acid battery, double flash = good lithium battery). For a battery unable to retain at least 12.4V, LED #6 will light and the program will immediately progress to STEP 6. Read the section NOTES ON TEST RESULTS on reasons for poor test results or how to test a battery that returns a good result but cannot deliver sufficient power once it is returned to service.

6. MAINTENANCE CHARGE: LED #5 / 6

LED #5 or 6 indicates depending on the outcome of the voltage retention test.

The maintenance charge mode is designed to preserve the DC source battery whilst maintaining the battery connected for maintenance at full charge. Intermittent charge is delivered to keep the battery maintained at full charge.

Charge is delivered when voltage of the maintained battery reduces below 13.2V and continues until the voltage reaches 13.6V. LED #5 or 6 indicates continuously during the charge period. After reaching 13.6V charging is interrupted and the voltage is monitored. During battery monitoring mode LED #5 or 6 will flash. The Maintenance Charge (STEP 6) and Voltage retention (STEP 5) alternate and repeat every 30 minutes until either the SOURCE battery (or DC supply) or MAINTAINED battery is disconnected or the SOURCE battery is completely discharged.

NOTE 1: Current demand is determined by the battery and the circuitry connected to the battery. A higher current demand will deplete the source battery faster.

NOTE 2: If during the MAINTENANCE CHARGE a battery voltage drops below 12.4V, possibly due to a high current draw from an external circuit connected to the battery, LED #4 CHARGE lights and a continuous 2A charge will be delivered.

Maintaining a battery for extended periods: The OptiMate will maintain a battery whos basic condition is good, for months at a time. At least once every two weeks, check that the connections between the charger and battery are secure, and, in the case of batteries with filler caps on each cell, disconnect the battery from the charger, check the level of the electrolyte and if necessary, top up the cells (with distilled water, NOT acid), then reconnect. When handling batteries or in their vicinity, always take care to observe the SAFETY WARNINGS above.

Notes on TEST results:

1. If the red LED #6 lights a significant problem exists. The red LED means that after being charged the battery's voltage is not being sustained above 12.4V (roughly equal to 50% charge in a sealed AGM battery) or that despite recovery attempts the battery was irrecoverable. This may be due to a defect in the battery itself, such as a short-circuited cell or total sulphation, or, in the case of a battery still connected to the electrical system it supports, the red LED #6 may be signalling a loss of current through deteriorated wiring or a degraded switch or contact, or in-circuit current-consuming accessories. A sudden load such as vehicle headlights being switched on while the charger is connected can also cause the battery voltage to dip significantly.
2. GOOD TEST RESULT, but the battery cannot deliver sufficient power: Permanent damage within the battery may be causing excessive self discharge (caused by the battery itself, even a partly damaged battery may initially retain sufficient power, but lose power faster than normal there-after). Disconnect the battery from the OptiMate. After at least 12 hours reconnect and observe if SAVE LED #3 lights, indicating the battery was unable to hold charge. If CHARGE LED #4 lights the battery retained at least 12.4V. Or measure the voltage and compare to table 1 on page 2.
