Battery Question

[Pete Masterson]

In general, the larger the battery, the larger the amp-hour capacity is likely to be. Take a look at Trojan 105, 125, and 135 models. They share approximately the same 'footprint' (width x depth), but as capacity goes up, the height increases.

Of course, the ultimate limitation is what fits your space. Batteries are classed by "type" which is roughly based on amp-hours or CCA ratings -- but more importantly on the measurements of the batteries. For example, if my car takes a type 35 battery, I can generally safely select any brand that claims to be that type and it should fit the space available.

The downside is that some batteries may not comply with the standard measurements. When I purchased replacement house batteries (type 4-D), the replacements were about 1/2" wider than the existing batteries and they would not fit the battery trays nor would the hold-down clamps work without modification. Fortunately, I was able to line up a friend with a welder who was able to use some scraps of metal to enlarge the trays and hold-down clamps.

I was rather surprised by thatoccurrence, however.

I have been following the Battery thread for a while...
One question that I have, and probably should know the answer to, is what difference does the battery physical size make??
One would assume that the larger a battery is, the longer it will take to discharge....
