My XP-1 Does not work in colder weather

Dear Antigravity Folks, I've had my XP-1 for over 4-years now, It always started my vehicle in warm weather, but never worked below 30 deg. I've only used it about a dozen times, but in cold weather it shuts down, all the indicator lights go out. I bought this mainly for emergency's and keep in my trunk. I check the charge every 2-months. I've been looking at the XP-10 HD, but the online reviews don't sound promising. And I don't need another XP-1 problem. What are your thoughts. Kindest Regards. 129 Skinner Hill Rd. Stroudsburg, Pa 18360

Stay away from Antigravity batteries I bought the xp-1 used it once and now it will not hold a charge.So much for keeping it as an emergency tool I'm going to try the Costco one for half the price

Reason of review:
Bad quality

I had a XP-1 Micro-Start that swelled and caused the hard plastic case surrounding the battery to burst. I contacted customer service by E-mail and they requested a photograph of the battery and of the hologram.

I sent these things to them by e-mail and in turn, I received a new XP-1. They didn't even care that my warranty had expired several months prior to the incident. I couldn't be happier with the result.

I'd like to suggest you contact them. In my experience, they seem eager to make customers happy.


Well they don't take care of there customers either they are crooks and thief's I only wish this would get to the ceo but they don't care they use deceptive practices to get your information then the sell it I dont know which politician getting his *** suck bit they let them do what they want I'm looking for people that can get as many of their card's max them out then don't pay it back tell they didn't read the fine print when you excepted the card about paying it back then send them 5.00 a month for each card and let's see how deep their pockets are

Yours sincerely
