Li-Ion battery 3.7V 2000mah and Li-Po battery 3.7v 3000mah what is the range for long-term storage mode for these two batteries?

Here are the specific storage voltage ranges for the two batteries you mentioned:

  1. Li-Ion Battery (3.7V, 2000mAh):
  • Storage voltage range: 3.7V to 3.85V.
  • Ideal storage voltage: Approximately 3.8V.
  1. Li-Po Battery (3.7V, 3000mAh):
  • Storage voltage range: 3.7V to 3.85V.
  • Ideal storage voltage: Approximately 3.8V.

By maintaining the storage voltage within these ranges, you help prevent degradation of the battery’s chemistry, thereby preserving its capacity and extending its lifespan.

Does MAH have a lot of influence in determining the storage voltage range?

Does the ideal voltage of 3.8v make a big difference in reducing battery life if I use the range 3.7 to 3.85v?

Hi @gamer87272298,

Capacity or mAh doesn’t affect the storage voltage of a cell.

The best way to think about storage voltage is like an elastic band. You wouldn’t want to store it in its stretched out / high potential energy state. Storing a battery at full charge or at 0 charge is the equivalent of it being stretched. Storage voltage is its relaxed state.

As long as Li-Ion are kept near the storage voltage and not at the extremes of fully charged or discharged they should be fine.

where did you get this information that long term Storage Voltage Range: 3.7V to 3.85V

Probably Google or Wikipedia where you or anyone else could get it.
I think you have asked this question before. Or someone else has not so long ago.

Hi @gamer87272298,

As Bob said you have asked a similar question before.

If you haven’t already I highly recommend reading through MIT’s Lithium Ion Battery
Safety Guidance document as it has a lot of in-depth information in regards to handling batteries safely.

PDF shows some 3.8v not range good for longtime storage

Hi @gamer87272298

The PDF recommends you store the batteries at 3.8V as seen below.

You originally bought this subject up on 28/05/24 and were directed to the MIT article on 03/06/24.
And here you are 2 months later bringing it up again.
What part of that last post did you not understand. I thought it was pretty comprehensive.

My personal suggestion would be to properly dispose of anything you will not be using for some time and when you need it purchase new items.
That will save you all this worry about storage.
Cheers Bob
