Dead batteries
Apr 17, 2020 23:09:39 #
Thank you gentlemen. Your chat convinced me that I should check the battery on our Honda - which hasn't been used in over a month. It was dead and I have now charged it so it is ready for use tomorrow. I use a 97 Chevy S-10 Blazer as our daily driver so it wouldn't have been the end of the world, but the boss prefers riding in the Honda. I guess this shows how often my wife has gone out.

I have a ham radio (APRS) tracker in my van that also monitors temperature and voltage. The downside is that it also drains the battery! The upside is that I've used these to find intermittent problems (a loose bolt behind the fuse block turning the fan on) and bad batteries (sudden 2 volt drop overnight.) I've got a solar panel on the dashboard that helps during downtime.
Here's the data it sends out: http://www.findu.com/cgi-bin/tele1.cgi?call=n3eg-9&last=168¶m=1&b=0.1&label=Vehicle%20Voltage&units=Vdc&autorange=1

The older Corvettes could be a 4 hr. job to replace a battery. I have a 2002 GMC P/U. It sat for a month in the winter. I went out on a -12 degree morning, turned the key, 2nd roll it started. Went and jump started 3 neighbors cars. On the older GM alternators the engine had to turn over 1800 rpm to get the high charge rate. It only put out a low rate at rpm less then that.

Most alternators need higher R.P.M.s to put out full amperage, there was one we used on shuttle buses that had a max output of 200amps @ 1700r.p.m.s and 75amps at idle. the down side was it cost over $500.00, however it was an exact replacement for the O.E.M alternators.

I may be showing my age...but....I remember when replacing a battery was a simple task. Now however...
I recently had to replace the battery on my 2013 Ford Escape. Step #1: Remove the windshield wipers!
Yep, that's right...to get at the battery you have to remove the WWipers to get at a panel under them, then remove the panel to get access to the battery cover, then remove the battery cover.

Remember removing the rear seat of a VW Bug?
I recall a 12v foreign car that has two 6v batteries. Can't remember the make.
