E6420 Battery E6430 E6440 E6520 E6530 E6540 T54FJ M5Y0X 8858X 97WH 9 Cell for Dell Latitude E5420 E5430 E5520 E5530,Inspiron 14R 15R 17R, 2P2MJ T54F3 4YRJH 0T54FJ 312-1325 312-1165 312-1163 PRV1Y

I bought this for my Dell Latitude E6540 laptop and it works great as expected. I would not hesitate at all to buy from this seller again in the future.

I was getting around 4 hours on the computer, and this replacement was able to extend that to around 7 hours per charge. It does add a bit of weight since the pack is bigger. But all in all its a good buy.

Works as advertised. Lasted as long as reviews from magazine sites state for this laptop with a 9 cell battery.

Hi - it doesn't fit - you can't snap it into place, and you can't open the lid to your computer all the way. The extension side is not made correctly so the gap between the extension part and the edge of the computer is too small.

Just started using for about a month, great replacement battery.

like this battery fitted my computer

The battery would not take charge when received. Bad battery. Back using the old one until I can buy one from others.

Replaced my totally worn out Latitude battery and worked OKI
