Battery Question
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.... Jack Smith 1973FC31 SoCal. |

Battery Question
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.

Battery Question
So, my batteries (according to the previous owner) are only about two years old
and they've been working fine. The other day I turned it off to register at an RV park and it wouldn't turn over at all. So, I had to start the generator to get enough power to turn it over. And, as long as we remain hooked to AC we have no trouble turning over. So, is this a battery issue or a charger issue? Jerry 85 PT40 |

Battery Question
Jerry,
Could be as simple as loose battery cables. In your routine (at least monthly) battery maintenance of checking the water levels in the batteries, check the battery cables for looseness and corrosion. Also check the other ends of the battery cables, in particular, the ground cable, as a poor ground connection could be the cause. If suspicious, remove the connection, clean any dirt/grime. Wirebrush both the cable end and the frame surface it attaches to, and re-install, using a inward facing star washer between the cable and the frame.

Battery Question
Jerry,
You may just have a connection problem at the batteries. I had a similar problem and after cleaning the battery terminals it has not reoccurred. Terminal cleaning is now part of my regular maintenance.

Battery Question
Could be both. The chargers are probably the OEM units -- notorious for overcharging and boiling away the water. The batteries can be easily damaged if mistreated. See the "new batteries" thread.

Battery Question
I didn't see anybody else suggest it, but it sounds like you may have an
alternator problem. If it will start after being plugged in it sounds like the chargers and batteries must be OK - there is no way that you can get enough power from the plugin/chargers by themselves to start a Detroit, and the batteries wouldn't do anything if they weren't charging. After a run down the road the chargers aren't in play, but the alternator is/are. On 6/29/2009 at 10:47 AM Pete Masterson wrote: >Could be both.
