Yuasa AGM Maintenance-Free Batteries

Yuasa AGM maintenance-free batteries have absorbed glass mat (AGM) technology. Once your battery is filled with acid, you'll never need to fill it with water or check the acid level. AGM batteries are ideal for motorcycles, scooters, ATVs, riding mowers, and personal watercraft. They feature a spill-proof design, which means there is virtually no possibility of leaks. These batteries feature advanced lead-calcium technology that pumps up starting power. AGM batteries also hold voltage longer and need less charging in standby or storage modes. This means that there will be much longer periods between charges when the batteries are used in a standby mode, like during winter storage. Yuasa batteries are available in nearly two dozen sizes and power options.
