Can it replace a 12V lead-acid battery?

Yes for light loads like fishfinders, radios and scooters. It gives the full 10Ah where lead-acid gives about half, but check that your device draws under 10A continuous.

Can I connect several together?

Yes. Series connections raise voltage and parallel connections add capacity. Use batteries of the same age and charge state and balance them before wiring.

What charger does it need?

A lithium LiFePO4 charger that charges to about 14.4V. A lead-acid charger can work if it reaches that voltage, but a lithium profile is safer.

Can I charge it in freezing weather?

No. Charging is limited to 32°F to 140°F, though discharging works down to -4°F. Warm the battery before charging in winter.

Will it run a trolling motor or inverter?

Not a large one. The 10A continuous and 15A surge limits suit electronics and small accessories, not high-draw motors.

What terminals does it have?

F2 spade terminals. Many applications need spade-to-ring or spade-to-post adapters.
