I had never changed a laptop battery before, so I looked up a guide online and did it in less than 15 minutes. Once you pop open the case, you basically just remove the screws holding in the old battery and replace it with the new battery. This battery fit well, but didn't sit quite as flush as the old battery. The screws went in just fine, and there were no complications. After the new battery was in and the laptop case back on, I turned the laptop on, and it started with no issues. There was no configuration needed. It just worked! It's been about three weeks since then, and I haven't had any issues with the new battery. It holds a charge, and the battery lasts longer than the old one. It also charges at a decent rate. Definitely an improvement over what was in there. I would've changed out the battery sooner had I known how easy the process would be. Also, I like that the tools are included with the new battery. Definitely hanging on to those for any future repairs! Update: I started having issues with my laptop dying on me when the battery percentage got low. My son suggested it was the energy saver feature on my laptop not playing nice with the new battery. He was right! I turned the energy saver off, and now the laptop doesn't shut off at low battery percentages. Just an FYI for anyone who might run into that. Review: Reliable Replacement Battery for My ThinkPad – Great Value! - I bought this Replacement Laptop Battery for my Lenovo ThinkPad, and overall, it has been a solid purchase. The battery fit perfectly and was easy to install. Right out of the box, it held a decent charge, and after a few cycles, it reached its full capacity. The battery life is good—not quite as long-lasting as the original, but it gets the job done for everyday use. I can get around 3-4 hours on a full charge, depending on what I’m doing. For the price, I think it’s a great alternative to an expensive OEM battery. My only minor complaint is that it took a little longer to fully charge compared to my previous battery. Other than that, I’m happy with the purchase and would recommend it to anyone needing a budget-friendly replacement. ## Features - Capacity: 5200Mah/48Wh; Cells: 6-cell; Voltage: 11.1V - Compatible P/N: PA3816U-1BRS PA3817U-1BRS PA3817U-1BAS PA3817 PA3818U-1BRS PA3818U-1BAS PA3817U PA3819U-1BRS PA3819U-1BAS PA3819U PABAS227 PABAS228 PABAS229 PABAS230 - TSKYBEAR CompatibLe with Toshiba Satellite C655-S5049 C655-S5512 C675-S7106 L645-S4102 L645D-S4056 L655-S5096 L655-S5150 L655-S5155 L745-S4210 L755-S5112 L755-S5216 L755-S5246 L755-S5153 L755-S5170 P745-S4102 P745-S4320 M645-S4070 L775D-S7340 Battery - 100% New from Manufacturer.
