![]() ![]() “For example, if your battery has three cells, you should charge it to 11.4V for storing it.”Īssuming you stored them at the correct storage voltage, your battery is probably safe to use. “If you plan on letting your battery sit for a few weeks (or four years), storage charge it to 3.8V per cell,” Abraham said. However, remember to slowly balance charge the battery before you use it again.” What voltage to store your LiPo battery atĪ fully charged LiPo cell is 4.2 volts, while a dead cell “My LiPo batteries which had been stored for more than eight years worked fine when I checked recently. “Four years of storage is not enough to ruin a properly stored battery,” said Mathayi Abraham, a professional electronics and telecommunication engineer, and founder of the site Robot Powered Home. To 18 months,” said Sarah Petrova, a hardware engineer at Intel.īut that doesn’t mean you can’t use them. “LiPo batteries show a significant drop in performance after 12 LiPo batteries don’t have expiration dates, but they can see a drop in performance after excessive use or passed time. So, you’re already doing the right thing to be concerned about using old LiPo batteries! While LiPo batteries are one of the safest forms of R/C battery, they can still be extremely dangerous if charged, discharged, stored, maintained, or handled improperly. Are they safe to use, or should I get rid of them? How long do LiPos last if stored at the correct storage voltage? And how could I test them to see if they are ok? ![]() They were stored at the correct storage voltage. I have two LiPo batteries with about 40 recharge cycles that I’ve been storing for about 4 years in an ammo box. If you have a question for Drone Girl, contact her here.
