I needed an internal battery replacement ASAP for my T480, as it would charge or boot up. This one had the fastest ship time, so I went with it. When I initially installed it, it worked ok, though it was definitely not the same amount of charge time as the factory one that came with my T480; it lasted somewhere between 2-3 hours, which was ok to get my laptop up and running since my external battery would still give me a good 4-5 hours. However, now, after only one month, the internal battery only holds a charge for about 15 minutes. Definitely not a reliable battery. I'm going to try and get an OEM.

Just wanted to say it does charge more than the 79% I had originally stated. The T480 has the max charging set to 80%. So it did charge to what the laptop wanted. The default max. charging on the Lenovo was 80%

This battery fit my Lenovo T480 perfectly. It also came with tools to assist with the install.

My ThinkPad only came with the external battery and not the internal battery. I purchased this battery to have both sets of batteries. I'm getting amazing battery life on both sets of batteries. This came with everything you need for replacing the battery including the screwdrivers.

I had some trouble installing this internal battery in my T470 which came with no internal battery. I wasn't pressing the connector deep enough. When it's fully inserted, only about 1 mm of the battery's connector is visible on the connector on the motherboard. Eventually I used quite a bit of force and it slipped in, and I knew it would finally recognize it and charge.I calibrated it using TLP in Linux, right at the advertised capacity. The computer detected it as an LGC made 5 months earlier with 1 charge cycle (the calibration). Together with the aging OEM 61+ external battery at 80% capacity, I'm now getting 13-14 hours battery life in Linux with the keyboard backlighting and screen brightness at 100%!I didn't try using the tools for anything. It seems most of these aftermarket batteries include them, but I'd rather use ones that I chose.Working on one of these T470s is probably the easiest computer modifications that I've ever done.
