I got tired of replacing batteries when they wouldn’t start my 04 GTO in winter after a couple of weeks waiting for snow to melt. I got a HF float charger for about $7 and never had a problem after that. You can double or triple battery life with a float charger.
I have 3 of them now and keep one on the HC in storage and move the others around on everything else. I really need a 4th. They are $10 now and I’m waiting for my next 30% off coupon! I know the HF rep, but some of their crap is really good!
Cost almost nothing, and sure fixes all the problems. So far, so good!
