EXTERNAL APPEARANCEThe cell / battery shall be free from cracks, scars, breakage, rust, discoloration, leakage and deformation4. WARRANTYOne year limited warranty against workmanship and material defects.5. WARRANTY5.1 Do not reverse charge batteries5.2 Do not short circuit batteries, permanent damage to batteries may result5.3 Do not subject batteries to adverse condition such as extreme temperature, deep cyclingand excessive5.4 Store batteries in a cool dry place, Always disharge batteries before bulk storage orshipment.5.5Do 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 seawater6. CAUTION6.1 Batteries should be charged prior to use6.2 For charging methods please referred to our technical handbookUse the correct charger for Ni-MH batteries6.3 Avoid batteries being used in an airtight compartment. Ventilation should be providedinside the battery compartment ,otherwise batteries may generate hydrogen gas , which could cause an explosion if exposed to an ignition source6.4 Do not attempt to take batteries apart or subject them to pressure or impact. Heat may begenerated or fire may result. The alkaline electrolyte is harmful to eyes and skin, and it may damage clothing upon contact6.5 Keep away from children. If swallowed, contact a physician at once.6.6 When using a new battery for the first time or after long term storage, please fully charge thebattery before use6.7 When using a new battery in use with semi-used batteries, over-discharge may occur. 6.8When connecting a battery pack to a charger, ensure correct polarity.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 overdischarge.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 placeout of direct sunlight.7、storage7.1 In order to ensure the battery to maintain the capacity level, We suggest Ni-MH battery andbattery pack should be stored under the condition of the -20 ~ 35 ℃, low humidity, nocorrosive gases 。

7.2 Ni-MH battery to avoid the high temperature or high humidity storage, otherwise it wouldlead to the battery leakage, rust, and the lower capacity7.3 The long-term storage may lead to NIMH batteries and battery packs to reduce the capacityand 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 cycles。
