Hello and good morning everyone. looking to a replacement laptop battery for my son's Dell laptop. hate to go OEM as they want $135 for a battery. has anybody found a good replacement for their dell that worked perfectly for them? if it was mine I would buy an aftermarket one and save a bunch of cash . after looking online there are so many out there that range from $35 all the way to $135. I know enough to check the specs and I just want to replace the 6 volt one he has now. can anybody suggest a place for a quality replacement ? thanks
