Using boost to start class A

Hi,

My starter battery is toast and need to replace it, I have had to use the boost mode to interconnect the house batteries to get it started.

Is this ok to do for another 6-8 starts or would I need to change it straight away?

Coach is a 8.1 gas vortec with 1 starter battery and 4 house batteries.

Thanks,

It kind of makes your alternator work harder then it need to support the chassis loads, charge a bad battery and charge the large house bank.

That makes it run hotter and strains the belt system.

If your trips are short, it may be OK.

You sure have nice house batteries. Lifeline AGM

.... and the Chassis battery is Deka Ultimate so that too is very very good battery.
Your boost did exactly what it is supposed to do. But unless your battery are very old, I would make certain there is nothing draining your battery and nothing would damage your new battery.

Hi,

Thanks for mentioning about the batteries, I thought long and hard about getting the Lifelines. I would of loved the 6ct but budget was a big concern. :-)

The starter battery is only 2 years old but I have run the slides one too many times without the engine running during the winter. They will charge up 12.65 over night but its just not enough to start it. I have to drive 40 mins to Cummins and then back and will see of she will start after. If not I pull it out and go get a new one.
