2.COSMETIC
Batteries should be without any flaw、stain、discoloration or leakage and deformation.
3.WARNING:
3.1 Do not dispose of cell into fire or dismantled under any condition.
3.2 Do not mix different cell types and capacities in the same battery assembly.
3.3 Charge and discharge under specified ambient temperature recommend to LEXEL specification
3.4 Short circuit leading to cell venting must be avoided.
3.5 Never solder onto cell directly.
3.6 Cell reversal should be avoided.

4.NOTICE:
4.1 Use batteries in extreme condition may affect the service life, such as: extreme temperature 、
deep cycle、extreme overcharge and over discharge.
4.2 Batteries should be stored in a cool, dry place.
4.3 Once problems be found,stop using,send batteries to local agent.
5. STORAGE:
5.1 It is strongly recommended to stored Ni-MH batteries and cells in the temperature range from
-20℃ to 35℃,and in low humidity and no corrosive gas environment, to maintain a reasonably
high capacity recovery level.
5.2 Avoid storage higher (e.g. 35℃), lower temperature than -20℃, or higher humidity which
would result in deterioration or damage to the cells and batteries such as follows:
. Permanent capacity loss.
. Electrolyte leakage resulted from the expansion or shrinkage of organic material inside the
cells.
. Rust of metal parts.
5.3 Up to three full cycles of charge/discharge after long-term storage may need to obtain highest
capacity.
