At most I get 2 hours battery charge which is better than nothing I have some protection in case the cable gets jostled now since the old battery is basically deteriorated into non-functionality ### ⭐⭐⭐⭐⭐ Worth to buy. *by M***R on October 25, 2025* Was purchased for IBM T420 PC. Works grate including charge and discharge cycles. Tested with original IBM battery utility. ### ⭐⭐⭐⭐⭐ Fits T-420 and W-520 for sure. *by T***R on August 25, 2025* Normally I use a company called Kahlon for computer RAM upgrades and battery pack replacements. They didn't have this particular battery in stock so I matched the part number and the specifications on AliExpress and Amazon Business. This one was an exact match for a Lenovo ThinkPad T-420 and W-520. It is the higher powered model with the extra row of batteries attached to the rear of the battery. It fits and works perfectly and the price was a bargain. I would buy it again. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/99458192-11-1v-94wh-55-sl410-laptop-battery-replace-for-lenovo](https://www.desertcart.sn/products/99458192-11-1v-94wh-55-sl410-laptop-battery-replace-for-lenovo) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-06-01*
