The charger for my old battery drill has died and I'm trying to
resurrect it. There are three connections to the battery, two larger
connections labeled "+" and "-" and a third connect, smaller and
labeled "T". The plus and minus connections are easy enough but what
is the "T" connection.
As some of the components in the charger are unmarked I have been
thinking of just connecting a 12 volt charger to the battery
connections and am wondering about what to do about the "T"
