Good info guys... I'm using them for maintaining not so much for charging.
During the summer I fish one or two days a week so won't need them then.
Come winter that's when I hope to see value.
Don't have to drag the charger out to top up the batteries.
Thanks SS for the tip ...I checked them out on the voltmeter so they seem to be working.
