Very happy. Confession, I didn't really take care of my laptop, banged the battery around, had a messed up charger that wore the battery out. Two years later in June 2021, I needed a new battery. I bought a second one for my Dell Latitude and again fits perfectly, bought a new charger and hope this battery lasts longer than two years. I would definitely come back to this vendor to purchase laptop batteries. ### ⭐⭐⭐⭐⭐ This battery lasts an incredibly LONG time...GREAT! *by A***T on December 24, 2017* I am going to keep this review short! I have a Dell e-7240 and this battery lasts FOREVER! I'd say this battery lasts longer than the original Dell battery, even when it was new! Comparing it to the DELL battery..this one is just a BIT lighter in weight which had me a little concerned..BUT seems makes no difference at all. My only semi negative is, the fit is VERY tight. It fits, but it may be a micro millimeter off in size but not an issue. I just had to push it into a place with a tad more force than the original, but then fits just fine matches the Dell really well too as to color etc.. It seems to take a longer time to charge than the Dell battery, but it seems to literally last almost twice as long. I am super satisfied with this replacement battery...for the price I think you can't go wrong here! ### ⭐ Battery has lasted less than one year *by B***F on June 26, 2021* The first battery lasted about two years then swelled up and had to be disposed. This one has swelled up as well but in less than 10 months. It started throttling my CPU to 30% (checked by Resource Monitor). I thought my laptop was breaking down but it runs fine when I remove the battery. I do not recommend this at all. ## Frequently Bought Together - K KYUER 7.4V 45Wh WD52H VFV59 Laptop Battery for Dell Latitude E7240 Latitude E7250 Ultrabook Notebook F3G33 KWFFN J31N7 451-BBFW 451-BBFT 451-BBFX 451-BBFY GD076 GVD76 HH J8KP NL CVF0 F3G33 W57CV - 68WH GJKNX Battery Replacement for Dell Latitude 5480 5580 5280 5288 5488 5590 5591 5490 5491 5495 E5480 E5580 E5490 E5590 Precision 15 3520 3530 Series GD1JP DY9NT 5YHR4 451-BBZG 7.6V 4-Cell - Samsung 870 EVO SATA III SSD 1TB 2.5” Internal Solid State Drive, Upgrade PC or Laptop Memory and Storage for IT Pros, Creators, Everyday Users, MZ-77E1T0B/AM --- ## 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.jp/products/51889863-k-kyuer-7-4v-45wh-wd52h-vfv59-laptop-battery-dell](https://www.desertcart.jp/products/51889863-k-kyuer-7-4v-45wh-wd52h-vfv59-laptop-battery-dell) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-11-12*
