storage
When storing your batteries for a long period of time (longer than two months):
• Charge your batteries every 90 days to avoid capacity loss. Batteries slowly self-discharge when left unused for a
long period of time; if the battery cells are allowed to reach a critically low voltage, their lifespan and capacity will be
permanently reduced.
• Always disconnect your charger from the wall outlet and battery before storing the battery.
• Avoid storing your batteries in extreme temperatures, whether hot or cold.
• Batteries are best kept in a cool, dry place. Do not allow batteries to accumulate condensation, as this could cause
shorting or corrosion.
• The recommended storage temperature for both SLA and Li-Ion batteries is between 32-77 °F (0-25°C).
• Avoid exposing the battery to extreme heat (104°F or higher) for long periods of time.
FaQ
Q: do i need to “break-in” my batteries?
A: Yes, it is recommended that you perform a “break-in” cycle consisting of ~ three discharge/charge cycles to allow your
batteries to reach optimum performance. This involves three complete discharges and three complete recharges. After this
initial “break-in” cycle the batteries will have maximum possible performance and less line voltage fluctuations under load.
Q: is it normal that the batteries get warm when recharging?
A: Yes, it is normal that the batteries will become warm to the touch during the recharging process. This is because the
increase of internal resistance and less energy conversion efficiency from electric energy to chemical energy.
Q: how long will my batteries last before needing replacement?
A: Average battery life depends on use and conditions. Even with proper care, rechargeable batteries do not last forever.
Conservatively, an SLA battery will come to the end of its useful life after ~200 full discharge/charge cycles, while Li-Ion
batteries will last about 500 cycles. A partial charge/discharge counts fractionally against those numbers; running the
battery down halfway then recharging it completely uses up one half of a charge cycle.
“End of useful life” refers to the point at which a battery can no longer supply 80% of its original rated capacity in ampere-
hours. After this point, the aging process will accelerate and the battery will need to be replaced.
