2. EXTERNAL APPEARANCE
The cell / battery shall be free from cracks, scars, breakage, rust, discoloration, leakage and deformation.
3. ELECTRICITY RETAINS:
Normal conditions with electricity retain 60%, if have special demands, confirm after negotiate.
One year limited warranty against workmanship and material defects.
5.1 Do not reverse charge batteries.
5.2 Do not short circuit batteries, permanent damage to batteries may result.
5.3 Do not subject batteries to adverse condition such as extreme temperature, deep cycling and excessive.
5.4 Store batteries in a cool dry place. Always discharge batteries before bulk storage or shipment.
5.5 Do not solder directly to cells or batteries.
5.6 If find any noise, excessive temperature or leakage from a battery, please stop its use.
5.7 Do not incinerate or mutilates batteries, may burst or release toxic material..
5.8 Do not mix new batteries in use with semi-used batteries, over-discharge may occur.
5.9 Do not remove the outer sleeve from a battery pack nor cut into its housing.
5.10 Never put a battery into water or seawater.
6.1 Batteries should be charged prior to use.
6.2 For charging methods please referred to our technical handbook.
6.3 Use the correct charger for Ni-MH batteries.
6.4 Avoid batteries being used in an airtight compartment. Ventilation should be provided inside the battery compartment, otherwise batteries may generate hydrogen gas, which could cause an explosion if exposed to an ignition source.
6.5 Do not attempt to take batteries apart or subject them to pressure or impact. Heat may be generated or fire may result. The alkaline electrolyte is harmful to eyes and skin, and it may damage clothing upon contact.
6.6 Keep away from children. If swallowed, contact a physician at once.
6.7 When using a new battery for the first time or after long term storage, please fully charge the battery before use.
6.8 When using a new battery in use with semi-used batteries, over-discharge may occur.
6.9 When the battery is hot, please do not touch it and handle it, until it has cooled down.
6.10 When find battery power down during use, please switch off the device to avoid over discharge.
6.11 Unplug a battery by holding the connector itself and not by pulling at its cord.
6.12 After use, if the battery is hot. Before recharging it, allow it to cool in a well-ventilated place out of direct sunlight.
7.1 In order to ensure the battery to maintain the capacity level, we suggest Ni-MH battery and battery pack should be stored under the condition of the -20 ~ 35 ℃, low humidity, no corrosive gases.
7.2 Ni-MH battery to avoid the high temperature or high humidity storage, otherwise it would lead to the battery leakage, rust, and the lower capacity.
7.3 The long-term storage may lead to NIMH batteries and battery packs to reduce the capacity and need 1-3 charge / discharge cycles to reach the maximum discharge capacity.
7.4 Three months after placing the battery need to be charge/discharge for one cycle.
