It's a Team's Life Why Get A Maxwell ESM ?

We were if for one heck of a surprise when we had our batteries tested.

A few weeks ago I started noticing that the generator was starting more often than usual for low voltage. I also knew it was about time for my annual major preventive maintenance service which includes battery testing and cleaning. So off to the battery shop we went.

Since we do have the Maxwell ESM ( Engine Start Module ) we only had three batteries to test. My plan was, once the original batteries failed, to install true deep cycle batteries. The truck was originally equipped with "dual purpose" batteries. These batteries work well but the flaw in this design, as I see it, takes properties from a starting battery, which is cold cranking amps (CCA), to start these big diesel engines. Then it takes properties from a deep cycle battery, amp hours (AH), which is the ability to power accessories for long periods of
time. These properties are then combined into one battery, however these properties are polar opposites for their duties.
