Batteries here in the North are an issue race car or otherwise. I go thru Trailer batteries on a two year cycle no matter what brand from cheapies to expensive. I am in and out of my trailers year round so they stay in place with tenders... still they fail. Not to pile on the Red top batteries I had two last 4yrs each. I researched the proper care and charge them but yet still they failed. I have moved on to Snyder Motorsports/Dyna\Batt batteries and happy with the performance plus a cost savings and 1/2 the weight.
But on to the point of the post. Thought I was set (and for the most part I am) but went out to the trailer and saw I had a soft tire (hadn't noticed it prior) down from 110 to 25 psi Took it off and looked for the leak.. none to be found (even after 3 days) Took it to a tire shop and told them to find it and fix it... they found nothing. So Im buying a new tire...that will fix it!
