Not only was the battery in tip top condition, well packaged and pristine, there was also literature on how to contact NinjaBatt (in case of problems) including discounts for future purchases, safety advice ect etc.I rate NinjaBatt based on previous experience. I operate a vintage Dell N5110 Inspiron - it is 10 years old. When the original battery failed a couple of years ago, I contacted Dell who, due to the age of the machine, directed me to a 3rd party to buy a replacement battery. At vast expense, as it was a "Dell" OEM, it arrived and was US. I had to use Nirsoft software to prove it was duff, send it back and, eventually, a new battery arrived - this took about 3 weeks and a lot of hassle!The NinjaBatt was considerably cheaper than the Dell OEM and has all the necessary safety devices fitted. It is a tad more expensive than similar products on Amazon but was right first time and safe to use.I would use this company again with no hesitation and strongly recommend their products. ### ⭐⭐⭐⭐⭐ This battery works well - much cheaper than the Dell original *by on Reviewed in the United Kingdom 24 September 2023* Good battery which works well in my Dell Inspiron laptop. Take care not to let it run down too low 'though - when there is too little charge left in it, Windows won't recognise it's there, and it's a complete faff to get it to show as working once it's re-charged (although it still does - just doesn't show on the screen) This is not a problem with the battery, just the software. ### ⭐⭐⭐⭐ Works for N7110 *by on Reviewed in the United Kingdom 18 October 2024* After some perusal I chose this battery for my Dell N7110. Having used it for about a month now, the battery life is fairly good.The only downside is that periodically, the computer's battery indicator light will flash orange repeatedly, and I think this is because the computer somehow detects that it is not an original battery being used. When this happens the computer also refuses to charge the battery.All is not lost however as removing the charging cable, shutting it down, and then reinserting the charging cable a few seconds after turning it on again will most times resolve the problem. This only occurs about once a week.Overall, I am pleased despite the niggle above. ## Frequently Bought Together - NinjaBatt XCMRD MR90Y Battery for Dell Inspiron 15 3000 Series 3521 3537 3541 3542 3543 3531 17 3721 3737 17R-5737 15R 5537 5521 14 3421 5421 Latitude 3540 3440 FW1MN - High Performance [6 Cells/49Wh] - 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 - Crucial RAM 16GB Kit (2x8GB) DDR3 1600 MHz CL11 Laptop Memory CT2KIT102464BF160B --- ## 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/132619845-ninjabatt-battery-for-dell-mr90y-xcmrd-inspiron-3521-15-3521](https://www.desertcart.sn/products/132619845-ninjabatt-battery-for-dell-mr90y-xcmrd-inspiron-3521-15-3521) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-08-04*
