Wow, that is a huge temperature change.

Hey, battery charger question. I have a two battery charger. Perko switch is in the All position. Slot 1 is for engine batter and Slot 2 is for the other three batteries. Which position does the Perko switch need to be in?
None/All/1/2?????

None, 1, or two... Not ALL.

Zat make sense? ALL is the one postion for the batt switch where all batteries are tied together electrically, and hence the outputs of the charger are paralleled. Any other batt switch postion and the outputs of teh charger are isolated, just like the batteries are.

Yup, makes sense.. Have been charging it on All since I have had the boat.... So, what is the damage that is being done??? Shorter battery life???

No, that would mean that the GF is prego....

I am not totally sure, and bet it will vary from charger to charger and install to install. My concern is that you have two different batteries or battery banks that are at different states of discharge. You also have two different charging banks in you charger. Multi-bank chargers are designed to charge two different batteries or banks simultaneously.

When you have the batt switch in ALL, the charger is running two outputs into a single combined load. Some chargers may not like this and may operate less effectively. It also probably provides a less than ideal charge situation; since the batteries are tied together electrically, they are charged by the same charge source. The deep cycle bank probably wants to be charged differently than the starting bank. When the batt switch is in the ALL position, you prevent that from happening.
