Default Universal SLA/AGM $39.00 free shipping

Been using these on my RV-10 and prior to that on my RV-8.
Dual battery system on both airplanes, always starting on both batteries.
Replaced at 5 year intervals just because they are cheap.
Never used a trickle charger and the plane occasionally sits for 3 or 4 weeks
during the winter season, no trouble starting.
The Bay area has a mild climate so not sure what the batteries will do in freezing cold.
Like Guccidude1, I use the old batteries to power my tug and other stuff around the house. At over 10 years of age they still take a charge and none has ever failed.
