My last RV spoiled me. It had maintenance free batteries...
While prepping for departing for Colorado on the 17th, I turned on the battery switch so I could check the propane gas level. Humm... the battery light was showing "E". I quickly attempted to start the genny, the starter was dragging. 2nd attempt, it started!
I let it run for about an hour and shut it off. About an hour later, I checked the battery again. It was back on "E".
Then it dawned on me. Check the damn batteries. Yep, there is no visible liquid in there.
I go to the store and pick up distilled water and, believe it or not, a snot sucker like you use to clean small children's noses. (all the while kicking myself in the ass for not checking the batteries on a regular basis)
The snot sucker is perfect for putting the water in the battery cells.
I was able to restart the genny and let the batteries charge for a few hours last night. This morning I checked the batteries and they are at 2/3. I will be charging them today, and checking them again tomorrow morning. With my fingers crossed.....
If you don't have maintenance free batteries, CHECK THEM SUCKERS!
