After experiencing frequent battery drain issues with my Lenovo ThinkPad T480, I decided to replace the internal battery. I stumbled upon this replacement battery from an unknown manufacturer and thought it was worth a try. The product listing mentioned compatibility with several Lenovo models, including mine, which gave me confidence in my purchase.
Upon receiving the package, I found that it included not only the 01AV421 battery but also two screwdrivers and an instruction manual for the battery replacement process. This was a pleasant surprise as I had never received additional tools with a battery purchase before.
Following the instructions, I managed to replace the old battery without any hiccups. The process was straightforward and the provided tools were sufficient for the task. The new battery fitted snugly into place and powered up my laptop without any issues.
Over the past few weeks, I’ve been using this replacement battery extensively. The battery life has improved significantly compared to the old one. I can now work for a full day on a single charge, which was not possible before. This has made a huge difference in my productivity.
However, it is important to note that while the battery life has improved, it does not match the original battery’s performance. The laptop still takes longer to charge compared to when it had the original battery. But given the improvement in overall battery life, I am willing to overlook this minor inconvenience.
In terms of quality and certification, the replacement battery meets CE/FCC/ROHS/UL certified standards, ensuring safe and reliable performance. The manufacturer also claims that it supports up to 1000 recharge cycles, which is a significant advantage over cheaper alternatives in the market.
Overall, I am satisfied with this replacement battery. It has improved my laptop’s battery life considerably and the tools and instructions provided made the installation process straightforward. While it may not perform as well as the original battery, the improvement in battery life justifies the investment. I would recommend this product to anyone experiencing similar issues with their Lenovo ThinkPad T480 or other compatible models.
