I recently purchased the 01AV420, 01AV421, 01AV489, 01AV419 laptop battery for my Lenovo ThinkPad T470, and I must say, it has been a game-changer.
Firstly, the compatibility is impressive. This battery fits perfectly with my T470, as well as other models within the T470, T480, A475, A485, and TP25 Series. It’s a testament to the manufacturer’s understanding of these Lenovo models.
The battery itself is a Li-ion type, with a capacity of 24Wh and a voltage of 11.46V/11.4V. I’ve found that it provides enough power to keep my laptop running throughout the day, even during heavy use.
One thing to note is that these notebooks come with two batteries – one built-in and one external. This battery is the built-in one. Before first use, it’s recommended to discharge the battery to 5% (not 0%) and then charge to 95%, and cycle this process 3-4 times.
Overall, I’m quite satisfied with this purchase. The battery has been reliable, and its compatibility across multiple Lenovo ThinkPad models makes it a versatile choice. If you’re in the market for a new laptop battery, I’d definitely recommend giving this one a try.
