How much starting power and runtime can I expect?

Designed primarily as a starting battery, the YTX20-BS supplies 270 cold-cranking amps (CCA) for strong starts in cold or temperate conditions and an 18 Ah capacity for accessory loads and short-term use when the engine isn’t running. It’s optimized for high current bursts required by large-displacement cruisers and ATVs rather than long deep-cycle discharge.

• 270 CCA for reliable engine starts in most climates.
• 18 Ah rated capacity for brief accessory use and cranking reserve.
• Sealed AGM design reduces self-discharge and handles vibration from heavy-duty applications.
