Dry battery Storage and Maintenance
Storage place should be clean, dry, good ventilated and not subject to weather changes.
Under normal condition, temperature should be kept within +10°C~+25°C, not exceeding 30°C by all means. Extreme humidity (for relative humidity higher than 95% or lower than 40%) should be avoided because it is harmful not only to the batteries but also the packing materials. Furthermore, batteries should not be placed near to any heating generators or long exposure under direct sunlight.
Storage in room temperature is the most common way to ensure the longevity of batteries. After all, a lot of people are living in tropical regions. To maintain room temperature 25°C is relatively easy. But if possible, storing batteries under lower temperature such as -10°C can even improve the longevity of batteries. During the storage period, batteries are better kept in protective packing (eg. Sealed polythene bags). During the process of unfreezing, the packing should not be removed. If the unfreezing process is too fast, water will condense on battery surface that is harmful to the batteries.
After the batteries are unfreezing to room temperature, they should be used up as soon as possible.
Batteries are often piled up if storage space is limited. In general, paper cartons should not be piled up higher than 1.5m; for wooden boxes, it should not exceed 3m.
Above-mentioned storage suggestions can also be applied to long distance transport. For sea shipment, they should be kept away from ship engine. In summer time, they should not be left inside enclosed metal containers where temperature can be extremely high under long exposure in sunlight.
The shorter the storage period, the better the battery performance will be. So, if possible, batteries should be delivered to end users via retails channels right as soon as possible after production. A good planning in warehouse management is very important. The first batches enter the warehouse should be the first one to leave. Different batches should be put in a planned array and labeled properly.
