40Wh XCMRD Battery For Dell Laptops - Compatible With Inspiron 3521, 15 3000 Series & More

About This Product

If your Dell laptop isn't holding a charge like it used to, this XCMRD replacement battery might be exactly what you need! With 40Wh capacity and 14.8V voltage, it's designed to be a direct replacement for your original battery. Compatible with a ton of Dell Inspiron models including the 3521, 15 3000 series, 3531, 3537, 5521, and many more.

Before you order, definitely check your specific laptop model by pressing Windows + R, typing \msinfo32\, and finding your \System Model\ - or just take out your current battery and match the model number. This battery uses Grade A NMC cells that ensure longer life and durability, plus it has built-in protection against short circuits, overheating, and overloads. The smart control chip means quicker charging and lower power consumption. You get up to 500 recharge cycles, which is pretty standard for quality laptop batteries. Installation is super simple - just slide the tab, remove the old battery, and pop this one in. Less than 5 minutes and you're back in business! When you get your new battery, do a few full discharge/charge cycles to activate it completely. Don't let it run down to 0% regularly, and if storing long-term, keep it charged. Much more affordable than buying from Dell directly but still meets OEM specifications!
