Spending winters in the south snd summers in the north I have acquired a few battery’s that need tending (seven to be exact). I tried three of Harbor Freight’s version and tossed them out after getting back to dead battery’s. I ended up buying Battery Tender Juniors and have been using them successfully for two years. They have a 4.7 out of 5 star rating and comes with a five year warrantee.
I've been leaning towards this one. Haven't pulled the trigger on anything yet. I need to take a look at Walmart, Autozone, etc. and see what they have in stock.
