| Subject: | Re: batteries and electrical |
Bill,
If with the new battery you're still getting some cranking hesitation, two things:
while cranking, look for a more than a half-volt drop between the battery
and the starter (using clip leads and a voltmeter); and see if a Battery Minder
charger does a better job of keeping the battery in good condition.
The difference between a large battery and a small one is internal resistance,
so a thicker cable with less resistance can be the same as replacing a smaller
battery with a larger one. Increasing cable gauge sometimes is less weight than
a larger battery; #4 gauge is a good choice for a 582. Also, shortening the
cable by six inches can be effective. Also, the sum of little voltage drops across
poor crimps, loose connections, and long/thin cables can add up to be more
than the starter can tolerate during engine cranking.
Batteries used infrequently have a short life; a Battery Minder will improve longevity.
A larger battery won't necessarily take longer to charge, but if the
smaller battery were not being fully-charged during flight, then the larger battery
won't be, either. So charging between flights is a good idea for that reason,
and a Battery Minder will do that. Also, a Battery Minder (as opposed to
a simple trickle charger) prevents sulfation, which shortens battery life when
they are infrequently used.
Hope this helps.
