This is a two-pack of Mighty Max sealed lead-acid batteries rated 12V and 12Ah with F2 (0.25-inch) spade terminals. They are deep-cycle AGM cells, so they can be discharged and recharged repeatedly and are sealed and spill-proof enough to mount in most positions. The 12Ah capacity is the common upgrade size for mobility scooters, electric wheelchairs, UPS units, fish finders and trolling motors, and two batteries cover 24V setups or a spare pair. Against lithium rivals they are heavier and shorter-lived per cycle, but they are cheaper to replace and tolerate simple constant-voltage charging.

Buyers of this size class of Mighty Max SLA batteries generally report they arrive charged and work as drop-in replacements for scooters, UPS units and trolling motors. Common complaints are shorter run time than expected on deep discharges and units that fail within a year or two.
