Replace your worn out battery with a new Dell 451-BBFX battery.
This battery is compatible with the Dell Latitude E7240 and E7250 laptops.
This 451-BBFX battery is a 4 cell thin battery but it also comes in a 3 cell version. This is the higher capacity battery which is the same physical size as the 3 cell battery, but has a 25% higher capacity than the 3 cell battery.
We use the highest quality lithium-ion battery cells that charge faster, last longer and weigh less. Our batteries last nearly 6 times longer than cheaper, lower quality batteries. We're so confident in our quality that we back each Dell battery with a 2 year warranty and 30 day money back return.
