Battery replacement
I Hello all
My laptop is Dell latitude 5285 2 in 1 Windows tablet. I want to change the battery and bought a battery with code name J0PGR (42 Wh) battery without looking for my built in battery. Once it had arrived, i dissembled my device and my battery says it was a 1WND8 (31.5Wh) battery. Both of them are of the same sizes and have the same screw ports. So i replaced the 31.5 Wh one with 42 Wh one…. After replacement, the windows BIOS clock started to give error… the windows couldn’t be logged in again with battery (so far ok if it is on AC power). At last, I changed back with the old one (31.5 Wh) again…. Here, i want to know that can’t they be changed if the models are not correct??? They said both of them are for Dell latitude 5285

Ensure that the battery is solidly connected.
Did you buy from a trusted source? There are many counterfeit Dell batteries.
Dell specifications state that your laptop can use 31.5 WHr or 42 WHr battery. Dell shop shows a different part number for the 42 WHr battery. But, Parts-People, a reliable source of genuine Dell parts, shows 42 WHr battery with the same part number that you bought, J0PGR.
So, assuming that you bought a genuine Dell battery and not a counterfeit, and that it is relative recent (within 1 year, preferably within 6 months of manufacturing date) it should work. There should be a white sticker on the battery containing a long alphanumeric string. If you post that here, we should be able to tell you the date, again assuming that it is not counterfeit.
Before opening the laptop to change battery or do any work, follow this procedure:
Whenever touching components or working inside a computer, wear a grounded wrist strap, also called anti-static wrist strap, ESD wrist strap, or ground bracelet. It's a cheap and sensible precaution. Rest the laptop on an anti-static mat or at least a reasonable alternative such as corrugated cardboard. (Repeatedly touching a metal case part is not sufficient mitigation with modern components.)
