AGMs in freezing temps

[arktos55343]

I am in Minneapolis. My AS is in storage...with a 50w solar panel (admittedly not getting a whole lot of sun right now) keeping a charge on the batteries (2 6v AGMs). I stopped in today to check on things...my multi-meter showed a charge of 14.57v at the battery terminals. I understand that AGMs are resistant to freezing....but 14.57v seems high on a cloudy day. I didn't remove the batteries because I am hoping for a break in the weather right after Christmas...so I can take off for Arizona. We're going to have several days of snow and extreme cold...and then back up in the 20s during the day.

Do you think my 4 year old batteries will survive this assault?

Thanks.

Sounds like the solar charge is working if that's the reading. As long as the batts are getting a trickle charge they will survive the cold.

Here is the Lifeline Technical Manual. Even if you have another brand, I would imagine the parameters would be similar. There is a section that discusses the temperature ranges.

Thanks very much for the useful information. I may need to put skiis on the AS to get out of town....the way the weather is shaping up.

Peaceful Holidays to all!
