How does the maintenance-free AGM design help everyday owners?

Absorbent Glass Mat (AGM) construction traps electrolyte inside the plates, so there’s no need to add water or manage acid levels. This sealed format reduces the chance of spills, tolerates varied mounting angles, and lowers routine service time compared with flooded batteries.

• No watering or acid checking required during normal use
• Sealed valve-regulated design resists leaks and vibration
• Better charge acceptance and lower self-discharge than older flooded equivalents

What performance and safety features should I expect?

UPLUS builds this battery using 99.99% pure virgin lead and controlled manufacturing to improve charging efficiency and reduce harmful emissions. The battery is rated at 40 CCA and 2.3Ah, balancing compact size with the cranking power commonly required by small motorcycles and scooters.

• Rated 12V, 2.3Ah with 40 CCA for reliable starting
• Premium raw materials to enhance longevity and consistency
