Yea, I know....Gel batteries again, But........ A friend bought a brand new Canadian made Gel Battery for his tug van. Never used it, and as he is now departing from caravanning, it's now mine. 11o amp hour, vehicle sized...... Now I know there has always been a million tons of controversy about the good's and bad's of Gel Batteries, (mostly on the price of them), and I'm thinking of using this one on our narrowboat....But what I'm not sure of is, can it be used as a starter battery? Much counter stuff on the web about this, and also 'hints' about special charging facilities to be used on a Gel......But no one explains why.... Can a Gel be charged with a standard alternator? I know they give limited 'load demand', but our boat engine is a three cylinder Lister, with very low compression for a diesel, so that's not a problem. Of coarse I would never buy one, but this is a freebi, and never used. Ta, Dave.
