RE Battery charger/alternator facts

[Guest]

Lubo,
I have used so far DMS Red Flash 3500 and DMS Red Top 30 and Optima
Yellow. I can't fail to notice that the DMS batteries may have a
quality problem, or it's just my hard luck. One died and was replaced
under warranty, in another the case was cracked by a clamp being a wee
too tight.
Next time round I'll probably go for Excide Maxxima. Try this:

Hi Guys
Sometimes I regret bringing up a topic, especially when it gets me in way
out of my depth, but I seem to be keeping up with this one.
I know thats because its a simple topic to follow but I enjoy being able to
keep track. Anyway enough of that crap.
I was wondering with all the different types of battery on the market with
all the different sales pitchs, ours are better etc etc.
Now this may seem a silly question but.
If you get a battery better than the 334 I think the cruisers have, will the
alternator be able to charge them or do they remain partially charged all
the time.
Im asking because I dont know the inns and outs of the charging system.
Does the alternator give out a certain charge, just enough to charge what
batteries we have or will it keep charging a battery untill it is full
regardless of what 12v battery that is.
How does the alternator know when the batteries are full.
I cleaned the terminals on the batteries days ago and every thing seems to
be ok, so maybe it was just the batteries were not charging because of a
build up on the terninals and when I went on that journey with the lights on
I was slowy draining the batteries.
Is that possible.

John,
It doesn't, but the battery does.
If there was resistance (i.e. crap) on the battery terminals, the
light would be dim and you would have problems starting the engine.
It's more likely that either the battery is not accepting full charge
(internal damage) or the alternator is not charging properly (diode
pack, cabling ...

Gel batteries are yesterdays answer guys. They have a problem in
that if they are charged at a high rate the gel gets bubbles from heat
in, these bubbles blow into holes between the plates that never
repair. With air gaps between the plates the capacity of the batteries
is reduced.
If you want todays answer then you use AGM batteries (absorbed
glass mat). These have a glass fibre mat between the cells that
contains the electrolyte but is not flooded. They will take more
punishment than most and are still spillproof. I have been using and
playing with them for about Five years now and they do perform well. A
good set of these will outlast flooded or gell by a couple of years at
the least.
The surge on a jump start is from the sick vehicle to the good
one when the owner of the former, overjoyed at hearing his engine
again, revs it to pieces to 'help' as soon as it starts. If you are
ever going to help anyone like this ask them not to do it.
Batteries will work with tap water but the impurities in it
seriously shortens their life, if you ever have a real problem and you
dont reckon on having your battery for much longer you could get away
with it. Roman's advice is good though, stay away from the fool that
said it.
As far as I know air bags are deployed by a shock sensor, not a
voltage surge. There is no voltage surge in an accident. Stop away
from this guy as well.
