battery issues

If the battery is performing well and if you get it tested and it is good, I don't see why you would need to replace it just because of time. It may last a few more years since you are not really stressing it.

Thank you all!

Question for you Mark.  For the past 5 plus years I have run my batteries until it shows on the wall gauge 1/3  full charge.  At that point I change over to my other battery.  Yet many posts claim that you shouldn't take them below 50%.  How do you check your battery while camping (wished I asked you that at the ERU in Traverse City this summer)?  I ask that because both my batteries will be 6 years old next March and still seem to be working well even though I have made it a habit to bring them down to 33%, at least according to that gauge on the wall.  I know how inaccurate that is when it comes to showing the black and grey water levels, maybe the same for battery charge?

Originally posted by Mojave1 How does the battery affect carbon monoxide levels? This is dangerous and you need to get to the bottom of it. The battery, when it gets low, causes the PROPANE detector to alarm, because it is hardwired. If the battery is tired you need to replace it. A Group 24 battery has about 70-80 Amp Hours of electricity. If your battery is healthy, I wonder what's pulling the juice? One possibility is the fridge. Never run your fridge on battery, as it uses a lot of current. Dry camping the fridge should be on propane. Heaters in general pull about 5 amp-hour, but don't run constantly. Even in cool weather, I think one charge on the battery is enough for a weekend. Pods have phantom drains, that can't fully be addressed. Furpod has a couple extra constant loads, I pull the fuses for those if I can when boondocking. But just sitting, we pull .165aH constant. Also, you don't want to discharge your battery more than 50%. The less you discharge it, the more charges the battery has in it (it will live longer). If you need more power. Consider a Group 29 battery (about 114 amp-hour, $99 at Walmart). Or two group 24 batteries (75 Amp-hour x 2). RV battery sizes by group are 24, 27, 29, & 31. Or two 6v golf cart batteries (about 200 amp-hours). When dry camping, I find my generator very helpful. For anyone who does a lot of boondocking, paired 6v's are the answer. In 6v's you get true deep cycle batteries, so if you do pull them down past 50% SOC, they will take the abuse better. And dual GC2s are the most aH's you can get on the rack without modifications to the rack. I'm speaking in generalities above. I don't know your situation. The purpose is to help you find an answer.
