Information about charging parameters
Rechargeable batteries consists of two electrodes which are contained in an electrolyte. A rechargeable battery is therefore a chemical element. Chemical reactions take place inside this element. These reactions are reversible, which makes it possible to recharge the battery. To charge a rechargeable battery, a so-called charge voltage is required, which must exceed the cell voltage. Moreover, the energy supplied during the charging process must be higher than that which can be drawn afterwards. This ratio of the energy supplied to the energy drawn is called efficiency.
The capacity that can be drawn is heavily dependent on the discharging current and has a decisive impact on the condition of the battery. The supplied charge cannot be used as a measure, because some of it will be lost during charging (e.g. converted into heat).
The capacity data given by the manufacturer is the maximum theoretical quantity of current which can be delivered by the battery. This means that a 2000 mAh battery can theoretically deliver a current of 1000 mA (= 1 A) for two hours. The actual value depends heavily on numerous factors (e.g. condition of the battery, discharging current and temperature).
a) Selecting the charging parameters
All parameters must be set correctly before each charge. Using incorrect settings can cause a fire and injury as well as damage to property.
b) Selecting the charging current
An excessive charging current significantly reduces the lifespan of the battery, and in extreme cases may cause a fire or explosion. Selecting the appropriate charging current for a battery type is therefore very important. The charging and discharging current are determined by the C-coefficient of a battery pack. For most conventional battery packs, the C-coefficient is indicated on the nameplate.
The requisite charging current for a battery is calculated according to the following formula:
Capacity in mA x C-coefficient = charging current in mA
Example: 1000 mAh x 5C = 5000 mA
A 1000 mAh battery with a coefficient of 5C requires a charging current of approx. 5 A. If you can't determine the C-coefficient of a battery pack, always use a coefficient of 1C and calculate the charging current accordingly. This is always a safe charging current. However, bear in mind that the charging times can vary according to the actual (but not verified) battery specifications.
For batteries with only one cell, the C coefficient is 1.

Operation
a) Placement
- Place the charger with the plastic feet on a non-combustible, heat-resistant surface close to a standard fused mains socket, if you wish to use it with a mains voltage. To use the charger with a DC voltage, the DC source must be located nearby or moved next to the charger.
- Keep the charger away from flammable or combustible materials (e.g. curtains). Never operate the charger on car seats, carpet or other combustible materials.
b) Connecting to the power supply
Never operate the charger with a voltage that is outside the range specified in the technical data.
- Alternating current connection: Connect the mains cable to the 100–240 V/AC mains connection (1) and plug the mains plug into a standard mains socket.
- Direct current connection: Connect the 7–17 V/DC voltage connection (8) to a suitable DC voltage source (e.g. laboratory power adapter) using a suitable cable with an XT60 plug (not included) (see "Technical data"). You can use power adapters or, in dry conditions, car batteries. However, consider the charging status of your car battery when you are travelling.
We recommend a battery with 2-4S and 7–17 V/DC voltage as a DC supply.
The charger has no short-circuit protection at the input. Never connect both power supply connections simultaneously. Do not attempt to operate the charger with an AC voltage and a DC voltage (e.g. a battery) at the same time. This will cause the charger to switch off and start repeatedly. This may damage the AC power supply, or in the worst case, destroy the charger.
c) Setting the parameters
- When the charger is connected to a power supply, it briefly shows the device logo and type, followed by the value of the input voltage. The 4 LED indicators light up in red and green until the charger switches to the standby display.
