Original battery finally expired. This one was a satisfactory replacement at a good price.

The original battery died and I bought this one. Preliminary testing looks good

I bought this battery for my e6510 laptop awhile ago and it’s been a solid performer. Wife has same laptop and her battery finally started showing it’s age. So since mine worked out so well and since I use mine quite heavily and it held up, it was a no brained to order the same battery again.These are excellent replacements for our Dell E6510’s and I’m sure they fit others as well.Good performance, great price and an excellent value shipped quick!

worked fine

I am frankly impressed "so far" got 2 hours out of it, still had juice though so I plugged it in, it's a great dealio.

Battery only lasted 2.5 months. Shuts off now at 45%. When laptop shuts down, pushing button on the battery fails 4 out of 5 times, but when it works shows 3 LEDs. Wont boot PC in this state until you plug in the power. When PC boots back up, battery shows 45%. I guess the 60 day warranty is issued because they know the battery wont last much longer than 60 days.

I have an old Latitude E6500 that this battery was purchased for.So far, the charge cycle on this battery is pretty close or slightly better than the factory original. The best value for the buck. I am keeping this old machine alive in order to install Linux on it soon, haven't gotten around to it yet but still running on Win 10. I would expect the battery life to be slightly better yet with Linux.The only thing that is yet to determine is the life span, but for such a small cost for this batter it currently has beat my expectations for it.

ce n'est pas l'originale de DEll mais elle fonctionne bien, je ne sais pas combien elle va durer

Parfait

My original battery lasted several years but this one barely made it to a year. Could only use it if it was plugged in and the low battery light kept flashing.

Works well

Came on time as promised. Right fit for my laptop. Very pleased.
