[5200mAh] Galaxy A51 Battery, EB-BA515ABY Battery with Repair Kit

Battery Works good, NOT an easy install but that is on Samsung for holding the phone together with double stick tape inside that needs to be pried part to remove the back of the case and then pried the battery off the phone. The phone was only keeping charge for about half day. Now after installing the new battery is has been running on the same charge for over a week. I'm impressed with the battery and would have done it sooner if I knew how bad my old battery was getting. the Screwdrivers they give you are so-so mystery material they worked for a 1 time install but I would throw them out after they are not quality but you can't argue for the price point they worked ok and you're buying a battery not some junk tools. The prying tool that looks like a guitar pick worked well, the screwdriver only had to take 3x screws out and while tightening up the 2nd last screw the driver was rounding over not the screw. 2x hardest parts were learning how to pop the front face bezel off, which required a lot more force to jamb the tool in than I expected for electronics, and the prying the case back off the phone battery was huge amount of force which felt like the phone was going to snap in half pulling it, I heated it up with a heat gun too per the instructions and it still didn't want to let go easy.

Samsung has been making battery replacement more and more difficult. Now in addition to having to deal with removing the fragile glass back cover due to the waterproofing you also have to remove parts of the phone. Six really tiny screws as I recall. Lastly the battery is glued in and needs to be carefully pried out. I should mention that the newer phones are fragile internally so care must be taken. This battery replacement kit contained all the tools necessary to do the job. So no hunting around for the right tool or having to make do with a not so right tool. In my case the battery swelled and dislodged the back cover. This made it easier to remove as long as you take your time and don't try to force it. Otherwise you will have to heat your phone and then slowly pry the back cover off. Consider also buying a replacement back cover. This way if you accidently damage the cover or just don't have the patience to pry it off slowly you're covered. Once you have access to the inside of the phone you need to remove like 6 screws. They are in tight and the heads can get easily stripped. This is probably the hardest part so be careful. Finally you should have access to the battery which will need to be pried out - at least that was what I found. I've been replacing batteries on Samsung phones since the S4 which was trivial by comparison. If it wasn't for the $150 price and a 1-2 day waiting for my phone I would have had the battery store replace this battery. If you choose this route you should be clear on what the process is if your phone comes back damaged which is why I have always swapped the battery myself.

For the second time this month I find myself with no phone due to an exhausted battery. With normal use this 6k mAh battery should have outperformed my OEM 5k mAh battery. It does not. At best it's a 4k battery. I am now looking at buying a new battery and going through the hassle of opening my phone for a second time. Not happy.

I used this kit to repair a swollen battery on an S22 Ultra. Perfect battery fit, quality tools, and despite the complicated procedures to actually replace the battery, this kit was able to revive a $1000 phone that was otherwise headed to the landfill. For a 20-something dollar investment in the kit, it paid off handsomely! Replacing batteries in these phones is not for the faint of heart, as you do risk the possibility of puncturing the battery (the one you're removing), and so you should make sure that is discharged as much as possible before doing the switch. Expect about an hour to 90 minutes to do this yourself.

The battery was a great choice..it holds up well

Worked great. I was able to power up the phone after replacing the battery. I was not able to charge it, but had enough power to transfer my data.

Just installed the new battery and it is working great so far. It was charged at 30% so I'm charging it now to full capacity, then I'll reset the battery settings *#9900#

Certainly did not hold a charge for what would be expected of a 5800 mAh battery, even after calibrating it thru several cycles, it still only lasted half a day...much shorter that the old original battery's current longevity. Returning it, and replaced with the 5600 mAh battery, which is lasting just a bit longer than the 3 year old 4855 mAh original unit. Would've been nice to also have included the back glass adhesive in the kit too.

Hasta ahora todo bien, dura muchooo más la batería, excelente calidad

No duró ni el mes.

El producto no me funciono, reemplace una bateria de 4000 mah usada por 5 años que ya se descargaba rapido y con la nueva de 6000 mah no hay diferencia. Como si no hubiera hecho nada. me arriesgue y perdií
