Excellent battery, worked well in my latitude 7480. Holds the charge and fits perfectly. Would purchase it again

I bought this battery as a replacement for a Dell Inspiron laptop, and it performed exactly as expected. Installation was simple, the system recognized it immediately, and the charge lasts a reasonable amount for everyday tasks. Considering the low price, it’s a great choice if you want to extend the life of your laptop without spending too much. ✅ Highlights: Fully compatible and works right away Great value for the price Perfect as a budget-friendly replacement

My computer was having issues booting up. The battery was slowly degrading over the years and I guess it finally discharged. My computer wouldn't start up correctly and never made it past the login screen. Never would have thought that replacing the battery would be the total fix.

The battery fit. Perfectly.

Actually I ordered a battery for this particular laptop twice, the 1st time 'guessing' it was the correct battery.....wrong! So then I did the logical more correct way of doing it, by extracting the old battery and using the 'model number' on it to search for the correct battery for my old laptop. That worked great, and so is the performance of the new battery. Great. It's working just like new now, almost. And I'll just return the 1st one. Amazon is great, too, but it helps to do things the logical way, and not guess. That's a little dumb, I must say.

Just what I needed. It fits perfectly.

I purchased this battery as a replacement for my Acer Nitro 5. After installation, it initially appeared to work correctly and charged to 100% without any issues. However, I later discovered a serious defect. When the laptop is left plugged into the AC charger, the battery slowly discharges on its own and reaches 0% within 3–4 weeks. Once fully discharged, it will charge back to 100% again — but the cycle repeats. This behavior is not normal. A properly functioning laptop battery should remain at or near full charge when the system is running on AC power. This issue strongly indicates a faulty Battery Management System (BMS). To confirm the problem was not my laptop, I reinstalled the original (old) battery. With the same charger and usage, the original battery held its charge normally, confirming that the laptop and charging circuit are not at fault. This replacement battery is fundamentally defective. Its inability to maintain charge while plugged in leads to repeated deep discharges, which will rapidly degrade the battery and shorten its lifespan. I strongly recommend avoiding this seller/product and choosing a higher-quality replacement with recent, verified reviews instead.

My battery was delivered by UPS in 40° temperature with the doors open on the truck. So I let it warm up to room temperature for 2 hours before I installed & charged it. My old Dell is operating like new again after also replacing the long dead CMOS Battery ( CR- 2032 button battery) on the Motherboard.
