I use one of those thermometers that you "aim" at the target. Some have a
built-in laser for aiming. So I'm really reading the outside of the case
and not the electrolyte itself.
Absent a mfg recommendation, I'm recommending 110°F because Surrette, which
used to recommend 125°F is now recommending 115°F.

Yeah, those laser thermometers are pretty neat. I gotta get one of them
some day.

Sounds like a good thing to have. I don't think my battery manufacturer
even gave me temperature specs. I guess you get what you pay for.
I'm using OutBack inverters with RTS (remote temperature sensor) so I've
never felt any need to take my batteries' temperature. It automatically
adjusts the voltage up to about 1.4 volts either which-way according to the
temperature. I don't know what it will do if they ever actually get too
hot. Now I have to go find out....

My understanding is that if they get warm, but within spec, water
consumption goes up. If they get too hot, the plates warp.
I've only seen mine get over 110°F on rare occasions -- and it was during
equalizations without using the battery temperature sensor -- but I was
monitoring things pretty closely.

I use a thermocouple that plugs into my DVM. I usually just tape the
thermocouple to the side of battery, so the above limitation applies.
