Fact or fiction about life of batteries in hot areas
Just curious...I was told yesterday that batteries in cars/trucks only last about 5 or 6 years in AZ heat. "Sitting in hot weather cooks them and shorten their lives". Fact or fiction?

The first underseat batteries attempted Ca/Ca construction which failed miserably. The Bosch philosophy included flat compensated voltage regulators which were set at 13.8 That value in conjunction with Ca Ca construction resulted in premature battery failure due to significant undercharging, in temperatures <10c
So the change was made to hybrid construction. This is why German OEM batteries were cruelly expensive in the sixties and seventies. The Ca/Sb battery proved to be better but few customers selected OEM as their battery replacement brand. Those were the days of 5% antimony automobile batteries. Bosch refused to budge on their corporate mandate of 13.8 volt regulation. Group 42 and 53 Bosch batteries remained Ca/Sb for many years. VRB batteries remained out of production until Delco brought out the semi-sealed Ca/Ca battery in the seventies. Now that VRB are common, the issue of housing batteries outside of engine compartments is common. Of Note are the Cadillac Allende remote batteries of the 1980's housed in the vehicle trunk, which incorporated the 1116412 Delco Voltage regulator in the CS144 alternator. The sense line to the regulator was controlled by a thermistor attached to the battery. The sense lead therefore ran from the vehicle trunk to the alternator voltage regulator. This system has been long obsoleted.
