Try the Delco's from Billy. He will get you a good deal on a very good battery. I have tried the Everstarts from Walmart as well as the Interstate batteries and have had bad luck with both. I had heard about the Delco T.M. batteries so that is what I now use on my boat in a 24 volt setup for my TM. I still use the Everstart for my starting battery because when it goes bad every 2 years they give me a new one. I bought my boat new in 2003 and have had 3 starting batteries up till now. I make sure my jumper cables are always with me. I think next time my starting battery goes bad it will be replaced with a Delco.
