Avoid this Gaisar line battery all together. Their 1-year warranty means nothing
on January 6, 2012
I bought one of these supper-capacity battery for my Dell D830 in September, 2011 from ATC LLC. It could only run my D830 for less than two hours when it was new, not any longer than the cheaper ones like the one I previously bought from another seller (TechOrbits, I don't work for this company). The gaisar battery failed in 4 months which did not surprise me too much as that is likely to happen with these li-ion batteries. Amazon's 90-day return time window has expired, but the battery has 1-year warranty. So I got "Gaisar" - the manufacturer's phone number from Amazon, and called them. But the guy of "Gaisar" in California told me the seller - ATC LLC is not their authorized dealer, and therefor they would not be responsible for the batteries from ATC LLC, and I should contact ATC. Amazon does not have ATC's phone number, but I managed to dig it out with google. I then called ATC. But the lady at ATC told me that I should talked to Amazon as the battery I bought was a "FBA", and would not give me a refund or exchange the failed battery. So I finally had to talk to Amazon again. Amazon initially suggested that I talk to the manufacturer - Gaisar for the warranty, but after I told them the whole story, Amazon agreed to issue me a refund - which is good.
My final advice - avoid Gaisar line batteries for the reason of difficult return/exchange. There are better sellers on Amazon, like TechOrbits (again, I don't work for TechOrbits), they have easy return policies.
