According to Battleborn Battery CEO Denis Phares, Battleborn Lithium Batteries can be charged at a slower rate than 1c at temperatures down to 24 degrees F. Their charging profile says to not use temperature compensation.

Some NOCO smart chargers include temperature compensation…but the temperature sensors are embedded in the charger, not a separate temperature probe.

Also, though I do not have AGM coach batteries, the Renogy solar charge controller has an added temperature sensor probe placed with the batteries, as well as the Victron smart shunt.

Note also that some (if not many) modern vehicle chassis electrical systems include temperature sensors in determining and setting the chassis alternator output voltage. As an aside, some chassis manufacturers also recommend and have procedures to adjust software controlling the chassis charging system for AGM batteries.

How does charging with solar impact AGM batteries? Our AGMs are now 6 years old, taken out each winter then back in usually May and either sit in storage or traveling with solar being used. Thank You.

When you replace them, go with Lithium. They are whole lot easier to maintain and cheaper in the long run. Mine stay connected to solar panels year round, under the bed.
