Batteries like this can be tricky. You don't know if you have a good one until after several months of use. So far , so good on this one. It charged up fine and seems to be keeping a charge. I bought the same model in January from another seller (THE BATTERY CENTER) and it is already useless and I could never get a response from the company. Fingers crossed on this one!

Love this battery. I was only able to get about an hour and a half out of the original battery. This battery kicks that up to about 3 or 4 hours on balanced power. It will prob be less if you are using a resource intensive program but more if you are just surfing the web or listening to music. the only disappointing is that it takes long time for recharging.

i like this item very much. it si stable when charging. what is more, it was chargded much less than dell shop. the only problem is that the shippign time is too slow.

it is really a good deal. when it is installed into my laptop, it is very compatible. i would recommendd thsi supplier to my lther friends.
