The Power-Sonic 12.8V 9Ah is a lithium iron phosphate (LiFePO4) deep-cycle battery built to replace small sealed lead-acid blocks in the same 12V slot. It holds a steady 12.8V nominal output, weighs far less than an equivalent lead-acid battery, and is rated for many more charge cycles. It suits alarm panels, backup power, fish finders, mobility scooters and small solar setups. Against lead-acid rivals it lasts longer and discharges deeper, but it needs a lithium-compatible charger and costs more up front.
