Dead battery usually isn’t the battery’s fault. It’s the key left on, a fan cycling, or a bike that sat a little too long between rides. The Antigravity Lithium Battery with Re-Start is built around that exact situation. Same compact lithium setup riders expect, but with a built-in safety net meant to keep you from getting stranded over something simple. This version is offered in YTX20, YTX30, and YTZ10 formats, covering a wide range of common motorcycle applications where lithium upgrades make sense.

How the Re-Start feature fits real riding

Re-Start is there for those “should’ve noticed” moments — lights on, accessory draw, or slow drain
Keeps a reserve inside the battery so you’re not immediately stuck with a no-start situation
Especially useful on bikes with accessories, alarms, or riders who don’t hook up a tender every time
Gives a little breathing room without changing how you ride or maintain the bike day to day
Once installed, it behaves like a normal battery until you actually need the backup

It’s not something you think about often, but when you do need it, you’re glad it’s there.

Practical install and usage notes

Match the battery model (YTX20, YTX30, or YTZ10) to your bike’s original battery size and requirements
Physical fit should always be checked, especially on bikes with tight trays or added wiring
Works best with a healthy charging system — lithium batteries don’t hide electrical problems
If the bike sits for long periods, proper storage and charging habits still matter
Riders running accessories tend to appreciate the added margin Re-Start provides

Quality and build notes

Antigravity’s lithium batteries are assembled with compact internal layouts and solid case construction. The Re-Start system is integrated internally rather than added on, keeping things clean and contained. As with any lithium setup, performance and lifespan depend on correct application and proper charging where applicable.

Battery models available

YTX20 — commonly used on larger displacement street and touring bikes
YTX30 — higher-demand applications with more electrical load
YTZ10 — smaller format for compact battery trays and lighter setups

This is a lithium battery for riders who’ve dealt with a dead bike once and don’t want to repeat the experience. Same weight savings and packaging benefits, with a little extra forgiveness built in.
