Energizer TX20HL 12V AGM Motorcycle & ATV Battery — 310 CCA, 18 Ah, Factory-Sealed Ready-to-Install

The Energizer TX20HL is a factory-sealed, ready-to-install 12V AGM battery that delivers 310 cold-cranking amps and 18 amp-hours of maintenance-free power for motorcycles, ATVs and snowmobiles.

Engineered for riders who want dependable starting power without the fuss, this Energizer AGM battery ships fully charged and sealed so you can mount it and go. Its absorbent glass mat (AGM) construction is designed to resist vibration, prevent spills and tolerate repeated charge/discharge cycles, making it a durable choice across street bikes, off-road machines and winter vehicles.

How does the TX20HL save time and hassle?

You don’t need to measure acid, pour electrolyte or run an initial charge—this battery arrives precision charged and sealed from the factory. That eliminates the multi-step setup required by dry-charge batteries and gets you back on the road or trail immediately.

• Comes fully charged and ready to install out of the box
• No acid pouring, sealing, or initial 8-hour charge required
• Factory-sealed construction reduces setup time to minutes

Will this battery stand up to vibration and rough use?

Yes. AGM technology locks electrolyte in glass mats, which minimizes internal movement and increases vibration resistance versus flooded designs. That stability helps maintain reliable starting performance in high-vibration applications like sport bikes and ATVs.

• Absorbent Glass Mat (AGM) design for improved vibration tolerance
• Non-spillable, sealed construction for safer installation and transport
• Designed for repeated charge/discharge cycles without performance loss
