PA3817U-1BRS Battery for Toshiba Satellite L755 C655 M645 L750P L600 L675 L675D L700 L745 L750D L755D M640 P745 Series, Fit PA3818u-1BRS PA3819U-1BRS

Arrived with about 65% charge. It functioned normally immediately after installing it. I fully charged it before allowing it to discharged to any real extent. The battery was easy to install, but one of the eyelets the screws go through had to be slightly bent to line up with the holes on the laptop. The battery life is better than the OEM battery for my 2020 Razer Blade 15 ever was.

Battery died and got this one for replacement. Great buy, did the job and got back on track..

I had issues when installing first battery. This company came through and sent me a replacement battery right away!

It fit perfectly in my lap top. It was charged @80% when I first received it and suggested to let it drain to 2% b4 recharging. It took 1.5 hrs to drain to 6% b4 my laptop turned off. I’ll see how long the battery lasts by itself after this recharge b4 giving it a different rating. I was hoping for a longer than 2hrs.

This battery gave my 2010 laptop a second chance at life. Its 2025, its literally on life support at this point. But I use it as a bed side streaming device to watch movies/youtube/anime. Its the little laptop that could at this point with more lives than a cat.

Ordered this item and installed it 4 months ago to replace my XPS 15 (9500) battery. Great price for a replacement battery but unfortunately my concern about not buying OEM came true. The replacement battery was always a bit buggy from the day I installed it. My original Dell battery was 4 years old and only lasted 1.5hrs fully charged. The great thing about this battery was that it lasted nearly 4hrs fully charged, however the problem was that when booting up or coming out of hibernation the laptop would suddenly shutoff once every 4-5 bootups. This was very frustrating and fortunately none of my files were ever corrupted. Starting from the 3rd month of usage the problem increased to once every 2-3 startups. I finally gave up when my chances of getting the laptop to startup was 50/50. Once at a client meeting my laptop failed to bootup 5 times in a row and eventually resorted to working off my iphone. My guess is the battery could not sustain the required voltage during windows startup/login and when windows would come on and start loading background apps like teams and one drive the voltage would drop and the system would shutoff. Even after charging the battery for an entire weekend I still had the problem. I removed and reseated the battery several times but still couldn't resolve the problem. The battery definitely degraded quickly over 3 months and roughly 3-4 charge cycles per week. I tested with the laptop plugged in and didn't have the problem, but that defeats the purpose of having a laptop. I eventually removed this aftermarket battery and went back to my old original dell battery for the past 2 weeks. I only get 1.5hr at full charge but the laptop has not shutoff on me once. I'm hoping customer service will replace my defective battery. I'm happy to change my review if I can get a good battery.

Works great an got here in great time.

Just what I needed 😌
