I am continually amazed that boaters will spend almost a thousand dollars more for AGM batteries to avoid a 10 minute check and water top off every 6 months and a one time switch change on their battery chargers.

East Penn made golf cart batteries are $95 each at my local Batteries Plus and probably cheaper elsewhere. They are used in duh, golf carts which is as demanding a deep cycle service as you will find. They have design features: more head room for electrolyte and bottom room for sulfate build up, that make them superior to any other flooded cell type.

They only downside other than the periodic water checking is that you have to install them in pairs. A pair of GC batteries is typically rated at 220 amp hours.

Three pairs will cost about $600 and will provide 660 AHs vs your 5 Lifelines at $1,445 which will provide 500 AHs. Is the extra $845 worth the convenience?
