OK here is something I wondered about... battery sizes.
In Response To: Battery and boat size question ()
I had no idea what a 4D or 8D battery was... or even Group 24 or Group 27. I just went to this site http://www.windsun.com/Batteries/Battery_FAQ.htm
They had listed various sizes... see the chart below.
U1 34 to 40 Amp hours 12 volts
Group 24 70-85 Amp hours 12 volts
Group 27 85-105 Amp hours 12 volts
Group 31 95-125 Amp hours 12 volts
4-D 180-215 Amp hours 12 volts
8-D 225-255 Amp hours 12 volts
Golf Cart & T-105 180 to 225 Amp hours 6 volts
L-16, L16HC etc. 340 to 415 Amp hours 6 volts
While this doesn't show the physical size, at least it gives an idea of the power available for each designation.

- There is no system -- just responsiblity and forethought that you need to check before you buy.
- There is also the shoehorn effect...
- The builder knows nothing about my battery system
- When I first found my boat I was shocked to find that it had only 2 group 27
- $d and 8D batteries are fine if you are not the one who has to move them..
