Digest Number 2005

Fred: You are correct, but the point I was making was wet-cell to AGM when I talked about amp-hours per dollar. The reason people choose the T-105 over the 8D is you can get more amp-hours into your battery compartment. And cramming more amp-hours in there gets very expensive with 6-volt AGMs.

Hi Folks,

Some added comment as this issue gets attention at least every 6 mos: As an example, the Interstate MHD-8D is advertized at 1400 CCA which is about 225 AH (divide by 6 as a rule of thumb, some use 5.8, others
6.2 to get from CCA to AH) and sell for about $175. The T105 sells for
about $90 each so the cost is close. And so are the weights indicating the lead content and therefore stored energy is about the same.
Conclusion - use is preferential. Look at the AGM weight for comparison.
