If you live anywhere with 4 seasons do not buy this
Be aware that the advertised cranking amps (CA) are not measured the same as industry cold cranking amps (CCA) CCA are measured at 0 degrees F, while CA are measured at 32 degrees F. So if your normal battery has 275CCA, you'll need to buy a Antigravity battery with 340CA to get equivalent power when it gets colder.

I loved this battery when I first installed it in the summer, so small and light!

The problems started when I kept riding through the fall into winter, I dreaded trying to start my bike in the morning. I had a whole ritual where I would "wake" the battery with the highbeams, turn signals, brake lights, and horn before I tried to unsuccessfully crank the bike over, it usually took me 3 times before the bike would turn over. The problems disappeared as the weather warmed back up but during my second winter with this battery, it finally left me stranded when it just couldn't turn the bike over anymore.
Recharging with a lithium tender no longer works and the manufacturer has been totally silent concerning a warranty.

I hate to give this product such a bad review because it's wonderful when it works in warm weather, I was able to drop nearly 10 lbs off my bike for $150, but the technology just isn't suited for someone who rides all year round in the northeast.

DoA, Nightmarish warranty process with Antigravity
Pros: Pretty paperweight

Cons: Dead on arrival, AG claimed deltrain lithium charger was not compatible so I bought their recommended optimate lithium charger, still didn't charge. ~5V when connected to either charger. Put in a warranty claim with AG, first they tried to make me pay shipping. Now they want me to pay 60% of the full price for my "warranty replacement" I have had the battery for less than a month.

Small and packs a punch
This little fella turns my 750 over on the first push of the button. That's saying something because my 82 virago carries a notorious starter problem that needs a punch early on before the gears start to grind. I'm pleased so far.

Amazing battery
Small and powerful batteries! The best part are all the informational videos to go along with the product so u know which one u need, even in unique situations where the upgrade needs to be smaller and doesn't necessarily need to be the same exact one.

Will this battery work for a 2009 Aprilia Mana 850cc?
A shopper on Jun 30, 2016
Does this battery need to be mounted upright?
Matthew R on Aug 30, 2017
BEST ANSWER: No. Hence the name "Antigravity". Great powerful battery. The 8 cell turns over my CB750 easily.
What do you recommend for a battery charger for this Antigravity 8 cell battery so the battery does no get damaged?
A shopper on Mar 24, 2015
BEST ANSWER: I use the Antigravity 4 Amp Lithium Ion battery charger, it also doubles as a trickle charger when I plan to let a bike sit longer than a few months.
I'm customizing my sportster trying to get the smallest battery possible how small can I go and still be ok?
