    I just use a candy thermometer. It's measuring at the low end, but it fits in the battery fill hole.

    Just watch using any sort of metal stem thermometer--They can short the battery plates (all sorts of no-fun can occur).

    I looked up photography (dark room) thermometers, but they are not as popular these days--for some reason. :p

    You might try to get an IR thermometer (not too expensive these days)... Probably close enough for government work. Safe. And very quick to scan batteries and connections looking for hot spots.

    Thanks for mentioning not to use metal to check the temp. I was going to use the clamp meter tester.

    I like the point n shoot handheld IR meters too. Mine even came with an little laser/led to make it easy to pinpoint the aim.

    It came in handy when I was trying to revive an old agm in 95F weather, and caught one cell in my 6-cell 12v battery going waay hotter than the rest - so avoid thermal runaway I caught it early I suppose and just recycled the battery rather than spend any more time on it. Also handy for spot-checking interconnect wiring, and a loose terminal lug. Pretty handy to have.

    I made the " Bat Temp " to take the guess work out of knowing the battery Temperatures after I found the the RTS and BTS were as much as 10 deg off from the actual temperatures. Knowing the electrolyte is what I go by.
