Why does the jump starter battery drain so quickly, and how can I fix it?

1. Full Initial Charge: Please fully charge it before first use, as it may have run out of power during shipping and storage. 2. Avoid Extreme Temperatures: Operate between –4 -140 °F because extreme heat or cold accelerates loss.

How to maintain battery life？

1. Regular Recharging: If you won’t use the jump starter for an extended period, top it up every 2-3 months. 2. Proper Storage: Keep it in a cool, dry place away from direct sunlight and high temperatures.
