Returned that one and ordered another and it works great! First one was probably just one off. Easy to install. Small screw driver and plastic prying tool worked well for installation. Review: Great Seller, Bad Battery- Whether a Bad Unit or Uniformly Poor Batteries to be Determined - This is an update/supplement to the first review of a battery purchased from this seller, which follows below. I subsequently purchased another one in the hope that the first unit was an unlucky outlier. NOPE! The second battery has failed after only 5 days and about 5 charge discharge cycles! The terrible experience is reproducible (thankful for desertcart's 30 day warranty). In conclusion, AVOID, because what I want is a good battery, not a good seller (see following)---> This battery worked fine when it arrived,, and was actually slightly better than OEM internal Lenovo. It worked perfectly for a while, but .... After 31 charge/discharge cycles according to the Lenovo Vantage diagnostic log- it died....the capacity dropped from 24+ Wh to 7Wh after only a month of light use (31 cycles). Terrible product. Immediately after I sent a note about this situation, the seller refunded the purchase price. I asked whether it was likely this battery was an outlier, and whether there was a better, more reliable one he could send- since the further correspondence with the seller ,, about a week ago, there still has been no answer. Unless there is some mitigating explanation, I would not purchase another battery from this source. ## Features - Model Name: 01AV489 internal battery, Voltage: 11.4V, Capacity: 24Wh 2095mAh, Color: Black, Accessories: Two free screwdrivers for easy installation, Battery type: A+ 3-cell / Lithium-ion, 01AV421 01AV419 01AV489 battery for ThinkPad T470 T480 T570 T580. - Compatible with: 01AV421 01AV419 01AV489 SB10K97577 SB10K97576 SB10K97578 01AV420. - Fit for ThinkPad T470 T480 A475 A485 TP25(Anniversary Edition 25) Series. - 100% Brand New, Rechargeable more than 500 cycls over life of battery; High energy efficiency and extended battery life - Warranty: Rest assured with 60 days and 12 months Warranty, 24 x 7 Email Support. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07NZ5CR9S | | Batteries | 1 Lithium Polymer batteries required.
