Comments about Lenmar® 4400mAh Li-ion Laptop Battery for HP® & Compaq®:

Battery will not charge. Remains @ 48%. Computer (HP) does not recognise the battery. Display shows no battery detected. Removing battery and plugging back in shows battery charging then begins a charge and immediently shows no battery detected again and again. Tried changing charging cord but still does not work.
