360 Cranking Amps- (Cranking Amps are the power the battery has)

12Ah (PB Eq) - Amp Hours are the Capacity of the Battery

The Antigravity battery is the lightest, smallest and most powerful battery made.  It utilizes a NO lead, Nano-phosphate Lithium Technology and is Made in The USA!

It has a 3 Year Warranty.  Most Lead/Acid batteries (including Harley brand) have only a 1 year warranty.

It is up to 40% more powerful than the Shorai brand of lithium batteries, and is up to 80% lighter and half the size of Lead/Acid batteries.

This battery requires no maintenance, no trickle charger, is not damaged by heat or vibration and is non-toxic.

Because of the high power this battery puts out you will notice a faster turn-over of the engine.  Additionally you will have a larger ignition spark due to the fact that the voltages stays much higher than lead/acid on the starting pulse, this aids dramatically in starting the engine.

Non-Toxic green technology, longer life than Lead/Acid, and the only waterproof lithium battery!


You Won't Find a Better Battery For Your Motorcycle


Technical Notes:

If you are using the smallest battery possible for your bike to save weight (for example a 12 cell in a Sportster 1200) you may find it may be sluggish initially. But with each attempt to start the battery actually warms itself from the amp discharge and gets back its full strength and will crank over faster. Not recommended for any Sportster that has a parasitic drain (alarm, LED accent lights, etc.)

Sometimes it seems like a battery (lead acid or Lithium) is not turning the starter over quickly enough, leading one to believe the battery is going dead, Or that it is does not have enough cranking amps.  Many times the battery is fine, it is either the connectors, or the actual cables.  With high Cranking Amp batteries, since they have a Higher CCA than the OEM battery, they can especially benefit from a slightly larger cable that is capable of delivering the higher amps to the starter.

Does this battery require trickle charging?

In most cases no.  The battery is Maintenance Free and can hold a charge for up to a year PROVIDED  the bike/vehicle does not have a PARASITIC DRAIN or accessory taking the energy.  IF your vehicles charging system is in good working order and you do not have any “parasitic drains” on the bike you should not have to charge this battery.  If you do have longer layoffs, or you bike has accessories creating a drain  you can purchase one of our battery chargers specifically designed for the Lifepo4 technology. See our Batteries Chargers.

A trickle charger is required by Lead/Acid batteries because they have a Natural Discharge… Our batteries do not have this effect.

*Things like an alarm system, anti-theft system, LoJack, etc. are a parasitic drain on the battery.  Depending on how much they drain, if you go several weeks, or more, without riding, we suggest using the Charger/Tender to keep the battery up.


How do I charge the battery?

The Antigravity Battery comes ready to install, and start the bike/vehicle. You should never need to charge it.  However, if you do accidentally drain it, we do offer a specific “smart”Lithium battery charger that is specifically for charging Lifepo4 Lithium batteries.  It will charge the battery to it’s intended peak voltage and will shut off when the battery is charged.

You should NOT use  a automobile or motorcycle charger that is specific to Lead/Acid batteries!  They can cause damage to the batteries because they charge in a different way than a specific Lifepo4 Lithium Charger. They often have a Desulfinate feature or over voltage “Quick Charging” feature… both of which will damage the Antigravity Battery. Lead Acid charges in many case will overcharge a lithium battery ending up in damage which is not covered under warranty.

Warranty Info from Antigravity: All warranty claims are handled by Antigravity Batteries directly.  Do not contact your reseller (DK Custom) for warranty claims. Each battery is accompanied by a manual which includes full warranty information.

It is amazing how fast my starter turns over and how quickly it starts.  Got plenty of room for my Power Commander now too!  -Jeff
