Review: Good 12-volt battery for powering 115-volt AC inverter - I am using this battery effectively to power an inverter which runs a Black & Decker weed wacker used to clear weeds in front of my airplane T-hangar. There is no AC outlet near the hangar.
Review: Work great - Exact replacement batteries for my drive mobility scooter. Easily installation, fit right in place of the old o es. Seemed to last longer and be a little stronger. Big savings over original replacements. Charged them immediately after installing to make sure they were topped off.
