TREE.NB New 9 Cell 7800mAh Laptop Battery for Dell Studio 1735 1736 1737 KM973 RM791 US

Fit perfectly, but a great addition would be to add the star screwdriver to fit the back of the HP.

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

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.

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

This battery is not a perfect fit for the Acer 5349; I managed to install it and it functions; but it did not fit fully flush as the OEM battery did.

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.

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.

Worked flawless out of the box. I was given an old laptop and decided to fix it up and use it. The oem battery was toast and this was a direct replacement. Plugged right into the motherboard and started charging. I've been using this new battery for a few weeks and I get around 5hrs of battery life. If anything happens to the battery I update my review.
