3 Tips for maximizing the lifespan of a jump starter
Keep the battery level above 80%
We recommend that you recharge your jump starter at least every 3 months to keep the battery power above 80%. It can prolong your battery lifespan and prevent emergencies from happening.
Avoid extreme ambient temperatures.
Despite your device has a wider storage & operating temperature range than most other jump starters, at extreme temperatures, however, your device has a efficiency reduction, which may contribute to an overall degradation.
Avoid keeping it plugged into the wall outlet
Our product has a over-charging protection, it's fine to keep the jump starter plugged into the wall outlet. But we recommend you unplug your device when it's fully charged, which is good for a longer battery lifespan and prevent the battery from charge-discharge cycles.
