Was purchased k20 pro original battery from service centre for future use as my stock battery still have 68% battery health. So my query is will I charge that new battery to prevent it from self damage or store it without charging? Which thing affect it negatively?
Store it with around 50-60% charge. As per research and testing, that's the ideal % charge before storing batteries. Don't store it at 0% or 100%
Actually it's new unused battery with manufacturing date of 2020!
I think original battery are made in stock when phone is launched.
The point is service centres are never charge the batteries until it installed in phone's. Don't know how that much time batteries are survive without charging.

1)how you checked battery health ?
2) MI service centre providing batteries without installation ? Which city ?

Yes. Although Xiaomi itself stores batteries at 30% SoC (State of Charge). It's clearly mentioned on the battery packaging. Devices with Li-ion batteries are often sold in what is termed the "shipping mode" where the charge is kept at 40%.

I received my Poco F4 with 1% charge last month. Assuming it was stored at 30% charge then in 9 months it dropped by 29% due self-discharge. Under ideal storage conditions Li-ion batteries lose 2-4% battery capacity every year. I plan to get a replacement battery in 2nd year and maybe another in the 3rd year provided the service center agrees to return the original battery like in the case of my Poco F1.

Actually it's mandatory but I convinced them somehow.
"When customer need then you don't have the stock"
It cost me 1237 rs

Not really. A few percentage drop in battery capacity is not worth the headache. If the device is relatively easy to open maybe you can consider charging it to 40% or so every year until it's needed. Even if you don't I guess the battery should be good for 2-3 years of usage unless heavy gaming is in the mix.

Accubattery was really accurate in my Poco F1. It predicted drop in battery capacity earlier than the built-in kernel profile. Predicting Li-ion health isn't an exact science, more of a best guess scenario but the kernel profile is as good as it gets until Google can be bothered to implement one natively in Android.
P.S. Personally since the original battery was down to 68% I would have preferred to get the replacement battery installed in the device and kept the original aside. Battery is warranted for 3 months only. You never know if it's a dud although I would guess it's quite rare. I had got my F1 battery replaced when battery health was down to 65% although in my usage still good for 10+ hours SoT over 2-2.5 days. Once battery health falls below 80% it usually decreases rapidly thereafter.

I installed accubattery after 3-4 months of purchasing my phone and it shows my battery health as 87%, now after 4yrs it still shows 77% health, never uninstalled accubattery in this 4yrs so it has huge amount of data to predict my battery health, and its predicting capacity loss of 2.3% per year, don't know if my battery is good or accubattery doesn't work for me

Accubattery doesn't seem to work well in some devices for some reason or the other. Anyway most of the time battery health readings below 80% aren't really useful as it's not as if one can use the battery till the very end. It predicts 65-70% battery capacity in my 6+ years old Redmi Note 3 whereas SoT is down to less than half of the original values suggesting well over 50% degradation. In my older devices there's no kernel profile support to pit against Accubattery.
Store it with around 50-60% charge. As per research and testing, that's the ideal % charge before storing batteries. Don't store it at 0% or 100%
