Answers before you buy
Is the Fulbat FTX9-BS GEL strong enough to start my engine?

Nominal voltage is 12V and capacity 8.4Ah. Wiring two in series doubles the voltage, while parallel wiring doubles the capacity.
About the technology: gel
Very little gas escapes from a gel battery during normal use. Powerchairs and mobility scooters often use gel because it takes daily deep discharges well. Avoid fast charging a gel battery.
