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 issues in case of emergencies.
Avoid extreme ambient temperatures.
Despite your device possessing a wider storage and operating temperature range than most other jump starters, at extreme temperatures, your device has an efficiency reduction, which may contribute to its overall degradation.
Avoid keeping it plugged into the wall outlet
Our product has over-charging protection and, hence, it’s fine to keep the jump starter plugged into the wall outlet. However, we recommend that you unplug your device when it’s fully charged, which prompts a longer battery lifespan and prevents the battery from charge-discharge cycles.
