Can I replace my iPhone SE 1624mAh battery with an 1800mAh capacity?

The battery in my iPhone SE [1st gen, A1662] is failing and needs repair/replacing. I’ve noticed multiple sellers advertising upgrade option with their 1800mAh capacity, with same 3.82V, and for the same price?

Anyone else have experience with battery upgrades, specifically, with this device?

EDIT: 1800mAh battery appeared to be compatible; Unfortunately my iPhone needs an all new, urgent, repair (wholly unrelated to my initial query here). This is a forewarning to Anyone with (1st Gen) iPhone SE planning on making ANY Battery mods:

Be Aware of the incredibly delicate (albeit in all likelihood intentionally engineered to prevent non-Apple Certified Repairs) BATTERY CONECTOR. If that Socket ISN’T carefully uncoupled/disconnected prior to physically (prying) extracting the battery from it’s seat, You Will Most Certainly Corrupt the FL2400 Ferrite Bead Filter. Thereby rendering you iPhone’s charging capabilities NULL.

Incurring repairs that necessitate (experienced) micro-soldering. Costing you anywhere between $40 - $100 (for repair service alone — as of this writing, imo).

It’s important you uncouple the battery connector just as soon as the metal battery connector bracket is removed; Or in my case, the actual battery connector and NOT the (seemingly similar Lightning connector cable) directly above it.

tl;dr: To be absolutely safe, and cautious, without incurring any additional risk or repair time to you: JUST REMOVE BOTH Connectors, Immediately After Removing aforementioned Metal Battery Connector Bracket.

re: Is this what a damaged FL11 looks like on a iPhone SE?

It should be fine, I already used a few upgraded batteries on different iphone models. They wouldn’t probably sell it if was not possible. What you want to be careful for is the voltage, the phone will draw as much current as it needs and no more, so could technically have infinity mAh. The battery will just last longer…
