Is killing batteries three times too much?
I use a set of 6V golf cart batteries from Costco. The pair that is in my rig now is two years old and they only last a couple of nights before the low voltage alarm on my CPAP starts sounding. When t...

How not to have this happen again:
1. Don't take batteries taken down to 10V and then not charge up to 100% properly.
2. Only leaving batteries to charge for 2 days.
I didn't realize two days wasn't long enough to charge them back up. This is probably why this happened the last two weeks I was there. I was probably getting enough charge to get me through M-Th night for the first four weeks, but not reaching full charge. Eventually, I didn't get enough to last me the few days. In other words, I may have been heading into the field with (95%, then 90%, then 85%, and so on.)

The fix! :B
1. Don't take your batteries down to 10V. Ever.
2. You need a Black and Decker VEC1093DBD 40 amp portable charger. Only use the built in crappy converter for float charging and when you're on full hookups (leave your rig plugged in 24/7 when not camping and check water levels once a month).
Can the charger help recover the batteries I have or is this for future reference?

4. If you run your batts to 10V again, break out the hydrometer, you're going to need to know FOR SURE that the VEC got them back to 100%.
What do I do with the hydrometer? The "12V" site only mentions using it to test. Do I need to add something if they are low or is this just for information purposes?

Your problem is caused by not having a generator.
