PowerStar AGM mower battery

The PowerStar 12V 18Ah AGM battery is a direct replacement for the Black & Decker CMM1200 mower and the UB12180 model. It uses sealed absorbent-glass-mat construction so the unit is maintenance-free and ready for seasonal lawn care.

Drop-in fit with nut-and-bolt terminals

The battery measures 7.13 in long, 3.00 in wide and 6.6 in high and weighs 12.5 lbs, matching the original footprint. Supplied nut-and-bolt terminals let you secure the cables without adapters, freeing the mower’s existing wiring harness for immediate reinstallation.

Sealed deep-cycle design for steady output

Advanced AGM technology delivers deep-cycle performance across backup, scooter and mobility applications. The sealed case prevents electrolyte loss during normal discharge cycles, keeping self-discharge low and run-time consistent throughout the expected 4-7 year service life.

Questions about this item

How long will the 18 Ah capacity last before the mower cuts out under continuous cutting?

The 18 Ah rating delivers a 20-hour discharge rate; actual run-time depends on the mower's current draw and grass conditions.

Does the sealed AGM case stay cool during an all-day mowing session?

AGM construction minimises internal resistance, so the battery runs cooler than flooded types, but ambient temperature and load determine case heat.

My CMM1200 uses nut-and-bolt terminals — does this pack include the hardware?

Yes, nut and bolt terminals are supplied so the battery connects directly to the existing CMM1200 leads.
