Just wanted to drop you a line to let you know that these are the best batteries that I have ever owned. Just got the boat out last week and went fishing and trolled most of the day and the batteries are still holding up great. I can’t believe it, this will be the 6th year now and there is still no corrosion and I’ve only added water twice. I have to say that I fish every chance that I get which is about 150 days a year or so and would always have to buy new batteries every other year. For the little extra money that the Thermoil Batteries cost, it sure was worth every penny and was money well spent. I figure that I have already saved about $260.00 because every two years I would have to buy two batteries for my 24-volt trolling motor at around $65.00 each and believe me I think I’ve tried them all over the last 20 years or so.
Anyway I just wanted to let you know this and I will recommend your batteries to everyone that I know. I will drop you a line when the batteries finally give out but who knows when that we be. I wish you much success with your business, you have a great product.
