Battery + Charger Safety Instructions
We pay a great deal of attention to the design of every battery pack to ensure that we supply you with batteries that are safe, durable and have a high energy density. The battery cells have a wide range of safety devices. Each individual cell is initially formatted and its electrical characteristic curves are recorded. These data are then used exclusively to be able to assemble the best possible battery packs.
Despite all the safety precautions, caution must always be exercised when handling batteries. The following points must be obeyed at all times to ensure safe use. Safe use can only be guaranteed if undamaged cells are used. Incorrect handling of the battery pack can cause cell damage.
IMPORTANT! Analyses confirm that incorrect use and poor care of high-performance batteries are the main factors responsible for personal and/or product damage.
⚠ WARNING! Use only approved replacement batteries; other batteries may damage the lawn mower and cause it to malfunction, which can lead to serious personal injury.
CAUTION! To reduce the risk of injury, charge the EcoSharp® IBAT40 lithium-ion pack only in its designated lithium-ion charger, the iCHRG40. Other types of chargers present risk of fire, personal injury and damage. Do not wire
and sharp edges. Make sure the cord will not be stepped on, tripped over or subjected to damage or stress when the charger is in use. Do not use the charger with a damaged cord or plug. Replace a damaged charger immediately.
- Do not use an extension cord unless it is absolutely necessary – Using the wrong, damaged or improperly wired extension cord poses a risk of fire and electric shock. If an extension cord must be used, plug the charger into a properly wired 16 gauge or larger extension cord with blades that are the same number, size and shape as the blades on the charger. Make sure that the extension cord is in good electrical condition.
- Charger iCHRG40 is rated for 120 volt AC only – The charger must be plugged into an appropriate receptacle.
- Use only recommended attachments – Use of an attachment not recommended or sold by the battery charger or battery pack manufacturer may result in risk of fire, electric shock or personal injury.
- Unplug charger when not in use – Make sure to remove battery packs from unplugged chargers.
WARNING! To reduce the risk of electric shock, always unplug the charger before performing any cleaning or maintenance. Do not allow water to flow into the AC/DC plug. Use a Ground Fault Circuit Interrupter (GFCI) to reduce shock hazards.
- Do not burn or incinerate battery packs – Battery packs may explode, causing personal injury or damage. Toxic fumes and materials are created when battery packs are burned.
- Do not crush, drop or damage battery packs – Do not use the battery pack or charger if they have sustained a sharp blow, been dropped, run over or have been damaged in any way (e.g. pierced with a nail, hit with a hammer, stepped on, etc.).
- Do not disassemble – Incorrect reassembly may pose
- Store your battery pack and charger in a cool, dry place – Do not store the battery pack or charger where temperatures may exceed 104°F (40°C), such as in direct sunlight or inside a vehicle or metal building during the summer.
Information about the battery
-
The battery pack supplied with your cordless lawn mower is not charged. The battery pack has to be charged before you use the tool for the first time.
-
For optimum battery performance avoid low discharge cycles. Charge the battery pack frequently.
-
Store the battery pack in a cool place, ideally at 59°F (15°C) and charged to at least 40%.
-
Lithium-ion batteries are subject to a natural aging process. The battery pack must be replaced at the latest when its capacity falls to just 80% of its capacity when new. Weakened cells in an aged battery pack are no longer capable of meeting the high power requirements needed for the proper operation of your lawn mower, and therefore pose a safety risk.
-
Do not throw battery packs into an open fire. There is a risk of explosion!
-
Do not ignite the battery pack or expose it to fire.
-
Do not exhaustively discharge batteries. Exhaustive discharge will damage the battery cells. The most common cause of exhaustive discharge is lengthy storage or non-use of partially discharged batteries. Stop working as soon as the performance of the battery falls noticeably or the electronic protection system triggers. Place the battery pack in storage only after it has been fully charged.
-
Protect batteries and the tool from overloads. Overloads will quickly result in overheating and cell damage inside the battery housing even if this overheating is not apparent externally.
Information about the charger and the charging process
-
Please check the data marked on the rating plate of the battery charger. Be sure to connect the battery charger to a power supply with the voltage marked on the rating plate. Never connect it to a different mains voltage.
-
Protect the battery charger and its cord from damage. Keep the charger and its cord away from heat, oil and sharp edges. Have damaged cords repaired without delay by a qualified technician at an authorized Snow Joe ^® + Sun Joe ^® service center.
-
Electrical plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with grounded appliances. Unmodified plugs and matching outlets will reduce the risk of electric shock.
-
Keep the battery charger, battery(ies) and the cordless tool out of the reach of children.
-
Do not use the supplied battery charger to charge other cordless tools.
-
During periods of heavy use, the battery pack will become warm. Allow the battery pack to cool to room temperature before inserting it into the charger to recharge.
-
Do not over-charge batteries. Do not exceed the maximum charging times. These charging times only apply to discharged batteries. Frequent insertion of a charged or partially charged battery pack will result in over-charging and cell damage. Do not leave batteries in the charger for days on end.
-
Never use or charge batteries if you suspect that it has been more than 12 months since the last time they were charged. There is a high probability that the battery pack has already suffered dangerous damage (exhaustive discharge).
-
Charging batteries at a temperature below 50^ F ( 10^ C) will cause chemical damage to the cells and may cause a fire.
Protection from environmental influences
- Wear suitable work clothes. Wear safety goggles.
- Protect your cordless tool and the battery charger from moisture and rain. Moisture and rain can cause dangerous cell damage.
- Do not use the cordless tool or the battery charger near vapors and flammable liquids.
- Use the battery charger and cordless tools only in dry conditions and at an ambient temperature of 50-104°F (10-40°C).
- Do not keep the battery charger in places where the temperature is liable to reach over 104^ F ( 40^ C). In particular, do not leave the battery charger in a car that is parked in the sunshine.
- Protect batteries from overheating. Overloads, overcharging and exposure to direct sunlight will result in overheating and cell damage. Never charge or work with batteries that have been overheated – replace them immediately, if possible.
- Store the charger and your cordless tool only in dry locations with an ambient temperature of 50-104°F (10-40°C). Store your lithium-ion battery pack in a cool, dry place at a temperature of 50-68°F (10-20°C). Protect the battery pack, charger and cordless tool from humidity and direct sunlight. Only place fully charged batteries in storage (charged to at least 40%).
- Prevent the lithium-ion battery pack from freezing. Battery packs that were stored below 32^ F ( 0^ C) for more than 60 minutes must be discarded.
- When handling batteries, be wary of electrostatic charge. Electrostatic discharges can damage the electronic protection system and the battery cells. Avoid electrostatic charging and never touch the battery poles.
