SOLICE New E6400 Battery for Dell Latitude E6510 Precision M2400 M4400, fits P/N: F8TTW PT434 PT437 KY266 FU274 FU571 MN632 MP303 MP307 W1193 KY477[11.1V 90Wh]

This battery has brought my old laptop back to life. Previously if the power cord was removed I couldn't use my device. Running Ubuntu with quite a few emulation programs with VMs made it difficult to dig into a large project. Now I have the flexibility to walk around and continue working. Id say I get roughly 3 - 4 hours out of a charge with all the workload I put on the device it seems quite acceptable. Truly the benefit is the freedom to not be tethered to a wall. In fact I can now use my laptop for tuning my car again.

Battery looks to be high quality and fits laptop perfectly.

Fit my old Dell with no problem. Holds a charge well. Very good price.

Battery stopped taking a charge after about 8 months. Now what? Not a happy customer here!!! I rarely take this laptop with me...it's heavy and it's old, therefore it stays home and charged. Today was different...I took it with me with the intentions of getting extra work done in the field. Surprise....the battery failed to hold a charge...no power as in DEAD!!! Thankfully I had a charger with me and was able to get my work done. Bottom line...should have realized the price reflected the value of this battery. Keep the money as it was the price of a valuable lesson...YOU SELL JUNK!!! Never again!!

It’s been a month since I received the 9-cell 90Whr battery. I have a Dell E6410 with Ubuntu 18.04 as OS. Since the CPU is a 35 watt, the battery runs for about 6 hours. That includes a full movie of at least 2 hours and light work such as browsing internet and doing Microsoft Word tasks. I can imagine that with a newer 15 watt CPU the battery would last some 1.5 to 2 hours extra.

Battery fits and works

It wouldn't charge right off the bat for some reason. I ended up having to run the old battery all the way down, then restart the laptop on the new battery - without the charger attached. And THEN plug in the charger. The BIOS said the battery was fine, but the battery light was flashing orange / blue constantly. It might be because I swapped from a 6 cell to a 9 cell battery but that doesn't make much sense. It's odd, but works now - I got about 4 hours on my first test.

This is an amazing battery for $30 ! I bought this for my Lattitude E6510 for doing my school work. Lasts a little over 3 1/2 hours from a full charge, a little more than the Dell brand battery came with with it!
