My stereo overhaul consists of the following amps:
3 x Zapco Ref 1100.1
1 x Zapco C2K 9.0
Xantrex Truecharge2 40 amp charger
I am tossing around a couple of options for power. I have come across deal on some Sprinter (made by Exide I believe) AGM batteries for $70 each. Supposedly 110-120 amp hour capacity, built in 2008, and have been on a float charge ever since. No warranty, pro rated or otherwise.
Option 2 would be 2 x 8D batteries, w/ 435 minute reserve capacity each at 25 amps. They are around $180 locally, plus $10 core, plus taxes, so figure around $410, but they do have a warranty.
I am not sure how amp hours converts to reserve capacity and visa versa to ensure that I we are comparing apples to apples in terms of # of AGMs vs. 2 x 8Ds.
Each has their pros---flexibility with location in boat and w/ AGMs and ease of install, warranty (i.e. less cable and connectors) for 8Ds...
Each has their cons---no warranty, more cable routing, battery boxes, etc for AGMs and individual weigth and location restrictions due to size for the 8Ds
What other considerations are there here? What would you do?
