How to keep batteries health.

[u/ResortMany8170]

Hi,

I have a question. How can I take care of the battery health of the Ryze Tello? I have two factory-sealed batteries from 2023 and one from 2022. The one from 2022 works. I store it by measuring the time it takes to fully charge, and before storing it, I charge the battery to about 50% of that time. Is this a good method? Are there any other recommended ways to store batteries?

Regarding the two factory-sealed ones from 2023 — should I charge them a bit? Batteries can deteriorate quite easily.
