Battery for Galaxy J3,Upgraded 4300mAh Li-ion Battery Replacement for Samsung J3 J327A J327P J320V J320A J320F J320P EB-BG530BBC EB-BG530BBE/ Galaxy On5/ for Galaxy Grand Prime SM-G530

I have an older Samsung phone which constantly drained all other batteries. I purchased 2 other replacement batteries before trying this one and none of them would hold a charge. Until I bought this one. It not only charges quickly to 100% but it outlasts any batter I have used in the past, including the Samsung battery. I plan to buy another one so I never lose power again. Great product!

I'm embarrassed to admit that I had never changed a phone battery before. My J3 is three years old, and the battery was running down very fast, especially when I was talking on the phone, which I do a lot. A couple days ago it conked out after a conversation, and it wouldn't charge at all. I knew the moment had come to open up my phone and replace the battery with the one I had ordered in anticipation of this moment. I held my breath and did it, and my phone instantly came to life, charged on arrival at 76 percent. The phone is working better in every respect. The problem I had with my headphones not working is gone. And I can now go more than 24 hours without recharging, despite my heavy use. I am happy.

I have no way to measure the actual mAh but it was only maybe 25% charged so I charged it maybe 9 hours to full charge, phone says 99% one time and 100% the first time. Seems to be holding charge at least as well as the 6year old 2600mAh battery, perhaps those using this did not give it a full charge and discharge 3 times to burn in the full memory of the battery. Phone is not arguing at all over it not being a 'branded' Samsung, we will see how this progresses over a year or two. May try to get another different branded battery to try as well.

My Samsung battery started swelling and heating up. Luckily I was able to find this one and it was affordable. I did discharge it completely/charge it completely for the first 3 cycles as instructed. The battery life has been great and it works perfectly. Saved me having to buy a new phone. Be sure to follow the discharge/charge instructions!

This battery was amazing. It brought my J3 back to new phone quality. It charges fast and the battery life is even better than the original. A great value for the cost. Less than half the price of a Samsung replacement. Great customer service and fast shipping was a nice surprise.

This garbage stopped functioning after just one month.

It was partially charged when I received it. That was nice.

good battery but I have to add a tape at the bottom because it's slightly too small

Bought it for a used cell phone I was giving to my grandson. He says it is working very well. Stays charged for long time. No complaints.

Brought my old phone back to life. Battery life seems decent.

Needed a new battery for my daughters all cell phone and works well!!

Fits our J3's and adds capacity. I will have to watch carefully as it ages though. The last replacement worked for 4 or more years, but was swelling at the end of it's life and popped the cover off of the back of the phone.

I purchased this battery in December 2025 that replaced the battery I previously purchased that lasted about 5 months. I started having issues with the batter no charging in January, today I have had the battery on charge for 8 hours and it has only charged to 2%. To make sure that the phone was not the problem, I took the battery from another cell phone and it charged with no issues.
