Cathy, Carrie's advice is good. Also, there are some files in the AA_Electrical folder in the Files section of this forum that may also be useful. Some basic advice is in the TrBatteryFundamentals.pdf document. I use a single Optima BlueTop AGM for most of our usage, which is adequate for most normal travel and overnight usage (several days if light duty), though I also have another wired in the back of our tow vehicle with a cut-off switch, for longer stays without shore power. Be sure to get in the habit of keeping your T@B battery plugged into a float voltage source when not in use, or at least remove the ground lead to keep the parasitic loads from draining it faster than normal. I recommend Sam's Club (and Costco?) for good prices for your replacement battery. A benefit of the AGM battery is that it is sealed, rugged and maintenance-free, except for the need to keep it charged, like any other lead-acid battery. If you usually stay at campgrounds with electrical hookups, there is no need for a huge heavy battery.

It looks like we will have to replace our TAB battery. It just doesn't hold a charge for very long. What is the best battery to get? We do sometimes forget to plug in the TAB at home and we drain the battery. Any suggestions & ballpark prices?
Tahnks,
Cathy
