Batteries with single-stage charger
Our newly acquired TC has a single-stage charger that I plan to upgrade. It operates at 13.5 or 13.6 volts. How long can this charger operate without risking damage to the batteries?

It'll do fine until it doesn't. This is how a Wifco works yes/no? So why all the nods all of a sudden?
It all depends how you use the system. Full hookups, it'll keep the batteries charged until air temps rise above 85F
Heavily cycled batteries will sulfate and die a very early death.
Guaranteed....
Only nods are from that haven't learned. Wifco caters to the OEM and the first time RV buyer that doesn't know or care at that point.- It'll do fine until it doesn't. This is how a Wifco works yes/no? So why all the nods all of a sudden?

Guaranteed.... - I learned my lesson 20 years ago. Not long. Many will tell you you can do a lot of charging with a single stage and it will eventually charge but never complete without a 14+ boost occasionally. You need a little out gassing from boost charge and you want a float for storage if you have power there. With a multi stage, you check the level now and then but very rarely if reach for the distilled water. Of course AGM takes that out of the equation too if you can afford them.
- Check the water and top off at least monthly, and it is good forever. Most folks get tired of having to nurse the batteries regularly, so they get a 4 stage converter/charger.
- Question is...will you watch it close enough?
- Certainly no issues in the cold of Winter.
- Pretty much forever if you watch the water level closely.
