Last summer I started to notice that the battery voltages were consistantly lower than in the past, and unable to maintain a charged voltage for very long. It seemed time for a new battery. The original is a Deka Marine RV, which is not really a true deep cycle battery, even though it did a good job for the past 5 years. After some research, I settled on a Trojan 30XHS. It is a 130 AH deep cycle battery with 225 minute reserve capacity. It is a group 31, replacing a group 27. It should hold up to off grid camping a little better, and hopefully have a longer recharge life. Should be interesting to see how this performs.
