I own an electronic equipment uses 2000mA lithium polymer battery but I use this equipment rarely it is stored unused for months and years and I wanted to conserve this lithium polymer battery so that its maximum capacity and recharge does not fall to 1800mAh and it goes down, it was built to recharge 2000mah and I want to keep 2000mah of maximum recharge and I don't want to miss the recharge cycles of this battery

Getting the most out of lithium batteries usually means storing at around half capacity.
Then when required, the battery is cycled and recharged to maximum.
It depends on the source / quality of the battery in question but I doubt you will ever get full capacity.
Storing for months might be ok but years...?? I don't think any will last that long.
Check battery university online for recommendations.

I agree to store a Li-PO battery at 3.7V per cell.
I store the Li-PO batteries for my RC airplanes at the half-charged voltage every winter and they last for years.
I have the Li-ion battery from my daughter's first cell phone. It has been at half-charge for 22 years and still works fine.

I told you that "It has been at half-charge for 22 years".
Also it was never made too hot.
Also it did not have thousands of charge-discharge cycles.
Hello,
The battery university has a lot of information pages:

Here is the page for lithium polymer:

Hello,
Then read this page:
https://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
The temperature and discharge depth do have their influences.

0% charge means a dead lipo.
Don't read the recommended minimum voltage recommendations then..??
....and, as they say, there you have it.
Appreciate the recommendation.
I just wondered which brand you managed to get 22 years from without it puffing up like a blowfish.
Hello,
Here is the do's and dont's page:
https://batteryuniversity.com/index.php/learn/article/do_and_dont_battery_table
For storing lithium batteries they recommend 40% charge at a cool place.

Just now, I entered here and saw the Batteryuniversity Warnings Table that I did not see yesterday so I went there. It gave me a warning that my pc has a virus and that that Norton (I don't have Norton) will delete all my files. Microsoft Defender anti-virus software that I use says my pc is fine.
The 22 years old Li-Ion battery is Sanyo and has two AA size cells in metal cases with cardboard sleeves on top, spot-welded in parallel. The battery plastic case has a Sanyo label but the battery cells have no label. Today they measure 3.55V.
Many places, even Walmart still sell no-name-brand replacements for this battery.

Ahha.....not lipo's then.
Yes, I have seen Sanyo nicads last extremely long periods.
Back in the 80's when flying RC aircraft, it was a common practice to chuck out the nicads after 2 years. They were relatively cheap then and 2 years of cycling would see a slight depreciation but not too much.
Still, the aircraft at the time had a lot invested in them in terms of time and money.
Therefore, come the 2 year old point and chuck 'em.
Near fell over when I saw the flying instructor still using the same batteries after 7 years especially since they really copped a flogging.
BUT, seemed to work out ok.
Dodgy trainer lead used to create more fizzy moments than batteries ever did.
Tend to go to Eneloops now.
