New Laptop Battery for Dell Studio 17 1745 1747 1749 Series; P/N: N856P U164P M905P U150P 312-0196 9cell 11.1V 7800Mah/85Wh1

Since DELL no longer offers this battery (and for years no one else did) this is a great product for a still very productive computer. For safety and security we all know that BIOS updating is crucial - but without a working battery this could not be done on my Dell Studio 1749, leaving me vulnerable. Thankfully, this product solved that problem and with the BIOS updated the performance of my machine has improved as well. Battery fits perfectly! I would highly recommend this product.

Battery worked great made my laptop feel new

Do your research carefully to match the relevant specs. This fit my Dell laptop and appears exactly the same size and specs as previous original battery. I don’t typically use it on battery, but after a decade the computer was sending lots of warnings and hesitant to even boot up. It was time, fortunately this was a cheap bit of maintenance.

Battery easily fit in computer but failed to hold a charge. Attempted to charge with an external charger without success. Returned the unit ,awaiting replacement.Update: Replacment provided quickly, works perfectly.

This battery is a perfect match for my Dell Studio laptop. It arrived quickly, looks & specs are exactly like the OEM battery (minus the Dell brand), fitment is perfect, and works great. It was priced right and arrived quickly. Doesn't get any better than this. 5 stars.

The battery was a direct replacement and works beautifully with my laptop. I would use the dealer again when needed.

Great product that work just well on my 19 year laptop!

The battery arrived as promised, in good condition (new), and fit perfectly. Have encountered no problems. So far, it seems to work like the original battery. If I find that performance (battery life) is not excellent, I will come back and file a revised or new review.
