[SOLVED] question lithium battery

[cloudff7ps1]

I have lithium batteries and BP-5L and Xiaomi BM20 lithium polymer stored and I charge them using this universal charger. What is the recommendation for me to keep these batteries always in good storage for me to use in the future? what is the charging frequency without wearing out the cycles and maximum charging

Keep them charged between 20%~80%, this way they can last very longtime.

You said lithium polymer but the battery in the second picture clearly showslithium ion which are not really impacted by charging behaviour like the polymer batteries.

I don't know what batteries they are but I thought polymer lithium

using this photo charger i charge them up to 75% but they have an automatic discharge rate and i don't know how long and intervals i should charge all the batteries so they don't fall to a dangerous value in their useful life

You also can use the same process for Polymer lithium batteries.

A battery charged to 80% would last several months, you can check them like every 6 months, charge them to 80% again.

These two batteries that I posted are lithium, lithium polymer or lithium ions?

i charged them using the photo charger for 75% how long does the automatic discharge go down to the minimum possible% to avoid damaging the battery?

I am in doubt if these two BM20 and BP-5L batteries are lithium or lithium polymer batteries or lithium ions

the BP-5L batteries are 1800mah and the BM20 battery is 2000 I charged them using this photo charger for 75% after how many days do I need to recharge them again so they have long storage and durability?

I thought all lithium-X batteries suffered more stress at the extreme low and extreme high charge range (e.g. 0-5% and 95-100%)(?)

Store in a cool, dry place with no direct sunlight. Charge to ~85%. Don't drain below ~15%.
You may end up with no difference, or a month's difference, or a year's difference by following this. Other factors (like tiny defects in the battery and environments while the battery is being used) also come in to play.
