what batterys are you useing in your trailers i have been useing a sears deep cycle it is going bad and needs replaced ! whinch lights etc THANKS

Two 6 volt golf cart batteries from costco.....

I have the same Interstate, 1000 amp battery, in the trailer for the last 14 years!!!!..

I have a Superwinch 4500, 12 volt lighting when the 110v isnt plugged in...

secret is a Battery Tender.....

I use two group 34 yellow top Optima's, the same as the one in the car. So if the car battery has a problem I can swap them.

Costco brand of thier RV marine deep cycle battery, the biggest one 6 YRS+ in my trailer, CTD Ram and street strip cars with the battery in the trunks My enclosed car trailer has a 12V electric tonque jack Superwinch 4500 lb. winch, electric start generator and two 12V lights inside, no troubles as long as I remember to turn the lights off before locking the trailer up for the week

Optima Red top...I pull it out and put it on a charger for the winter though.

I have a NAPA deep cycle. keep a battery tender on it in the winter. going on 3-4 years old now/
