I received to review a 9-cell laptop battery for Dell Latitude E6410, E6400, E6500, E6510, Precision M2400, M4400, M4500, M6500, P/N's 4M529, Ky265, 312-0749. The battery type has a Li-ion capacity of 7800Ah , a voltage of 11.1V, and it has a battery life that recharges up to 500 recharging cycles.
The laptop battery came in a protective sealed cover (as shown in the picture above) it was easy to slide into my son's laptop very well. I noticed the battery does stay charged longer than my other laptop battery my son had, it stays charged for a long time without having to plug in the cable charger. So far he doesn't have no problems with the battery nor the battery life failing. Great quality, I highly recommend it! You can find it at Amazon
