SB10K97578 Internal Laptop Battery Compatible with Lenovo ThinkPad T470 T480 A475 A485 TP25 Series SB10K97577 SB10K97576 01AV421 01AV419 01AV420 01AV489 11.46V 24Wh 3-Cell

Decent price for a T480. Works, no issues. Holds a decent charge for now.

really low qualityNow the capacity is 70%

I received a defective battery that cannot hold a charge for more than 15 minutes.

Software reports 24.9 Wh after three compete charge/discharge cycles

True capacity was only 8wh/24wh, doesn't work

I was on the fence about if my 4 year old T480 battery needed replacement or not (70% capacity after 112 cycles) but decided to give it a shot with this Laqueena 24 Wh T480 battery. Installation wasn't complicated as I've removed the back panel on this laptop a few times now and have a smaller Philips head screwdriver with a magnetic tip to use. The included toolkit might be useful to some who have nothing. The smaller size Philips head screwdriver and plastic wedges may be helpful if you need tools for your battery replacement. The Laqueena battery has slightly longer wires and less "wrap" on those wires compared to the original, so a bit of wire training was needed to avoid components that might heat up on the motherboard.The Laqueena replacement battery is programmed indicating a 2020 manufacture date and first appears to have been tested in April 2022 (that's probably closer to the actual production date). After a few days of use I used the Lenovo battery gauge reset tool and it reset the battery capacity to 24.27 Wh, which slightly exceeds the 24 Wh claimed.So far, things are fine with this replacement battery and I'll update the review if any issues arise. I'd suggest you use your Lenovo Thinkvantage tools and inspect your own laptop battery's cycle count/reset the battery gauge to judge if it's time to replace your internal battery.

This isn’t my first experience with Laqueena batteries. As an IT professional, I’ve purchased them many times and they have always performed well. This one is no exception. I got it for my Lenovo T470 where the original internal battery was slowly dying.The box I received is nicely packaged to protect its contents. It includes the battery (in an anti-static bag), a toolkit for opening your computer and replacing the battery (4 screwdrivers with different heads, 2 picks, & 2 pry tools) and a short but useful manual.For the Lenovo T470, you only need to loosen 5 screws on the bottom of the case to open it. Then another 2 screws release the battery. Disconnect the power connector and you’re ready to swap batteries. The connector is keyed so it can only be inserted the correct way. You do need to be careful to push it in fully.The battery is rated for 23,940 mWh but when fully charged it slightly overdelivers to 24,160 mWh. That is significantly better than any other third-party battery brand that I’ve ever tested and used. Most batteries top out at around 80% to 90% of their rated capacity (rather than delivering over it).Overall, this is an excellent battery and it gets top marks from me.

Originally, I had low expectations for this internal battery for my T480, but I had been having problems with my original internal battery disappear every once in a while. I took a chance and got this Laqueena internal battery.Once you get the bottom cover off the T480, replacement is fairly straight forward. There are only 2 screws and a tab holding the battery in place. The connector cable (photo with red, yellow, black wires) is a bit longer than the original (photos with all black cable) and will require some creative routing to keep it from overlapping other components. Not sure how long pressing up against that component will last.As far as performance, it definitely exceeds expectation. The design capacity is 23.95Wh and after the first charge came it at 23.93Wh. Most 3rd party batteries always come in around 20% lower than advertised or rated capacity.NOT THIS ONE! After I did a battery reset with Lenovo Vantage, the full charge capacity showed 24.49Wh, almost a 0.5Wh higher than design capacity. I couldn't be happier with this battery and will likely buy from Laqueena again for my laptop battery needs.
