Try J.C. Whittney,
They have a product that you can put in you battery that extends the life
and power of you battery, battries, because it eats up the corrosive
sulfites that dammage the battery plates. Years ago I had another brand
trailer that came with batteries with a 36 month warranty and they lasted
for well over 10 years. It's only around $6 a tube and in my oppinion well
worth it!
