ANTIGRAVITY

Antigravity Lithium Motorcycle Batteries

Antigravity makes lithium-ion batteries and jump starters, and the catalog we carry is small and specific: about 16 products, all of them for motorcycles, snowmobiles and UTV/ATV use. They live in Batteries, with a UTV/ATV copy of that category in UTV | ATV Batteries.

According to Antigravity, the company is based in Los Angeles, was established in 2009 and builds lithium-ion batteries for motorcycles, powersports, automotive and race vehicles. It released its RE-START line in 2018, with a built-in jump-start feature that you trigger with the Restart button on top of the battery.

Batteries by size

Antigravity names its batteries after the size and the cranking amps (CA) in the product title, so the number you see is a real spec, not a model year.

Jump packs and accessories

We also list the XP-1 Micro-Start Gen 2, the XP-10 Micro-Start Gen 2, the XP-20 jump pack and a battery tracker for lead-acid batteries.

Check size, terminals and fit

A battery that fits one bike can be physically too long or have terminals on the wrong side for another, so read the dimensions and terminal layout on each product page, not only the list of models in the title. Compare the cranking amps with the number on your old battery and make sure the chemistry is right for your bike's charging system. Lithium batteries also need a charger designed for lithium, so check your charger before swapping from lead-acid.

Antigravity questions

What does RS mean? RS in the product name refers to the RE-START version, which Antigravity says has built-in jump-starting through the Restart button on top.

Do I need a special charger? Check the Antigravity listing and battery instructions. Standard lead-acid chargers may not suit lithium batteries.

Which one should I pick for a Harley? Look at the ATX12, ATX20 and ATX30 listings, which name Harley-Davidson models and years in the title, and compare the cranking amps to your stock battery.
