I don't think you can go wrong with BT, BM or Schumaker. Heck, the
Harbor Freight model might be OK; I wouldn't be shocked if they all
came from the same Chinese factory. Some will charge multiple
batteries at a time.<br>
<br>
Good summary of batteries and chargers here:

I got a good--read: expensive--SLA/AGM battery for my BJ8 after the
second time I had to remove my gas tank and acid-neutralize my boot.
My AGM charger looks just like your larger one, except it says 'AGM
Only' on it. The other one is the newer, lighter one I have; guess
I'll have to give it a second chance (could be my fault, I think I
tried to charge an AGM with it). <br>
<br>
I have an old-school trickle charger in good nick; anyone who wants
it can stop by my mom's house (it's not worth shipping).<br>

I use Battery Minder maintainers. The one I use on the Healeys
tells you the state of charge when you hook it up and goes into
charge mode. It automatically will convert to float charge when
the battery is near full. Of course it also has a desulfation<br>
mode built in also. Works great and you can leave it connected
for long periods with no adverse effects other than a fully
charged battery. I use lead acid batteries because I can get
reconditioned ones from the Interstate store for around $45. They
seem to last as long as a new one and the store is only 5 min
away. The other charger I use is also from the same manufacturer,
but it is the newer solid state "light" model. It is also smaller
with less features, but it also sulfates and changes modes
automatically as required to charge batteries. I use the small
one primarily on my Harley. See below.<br>

truck and Healey and are very happy with them. Battery
Tenders monitor and float the charge so prevent overcharging.
They come with either a plug or large alligator clip
connection. I've run a pigtail into the boot of the Healey
(I've a BN7 so the battery is not in the boot), and I've a
pigtail out the grill and under the rear bumper of my truck to
make plugging them in convenient. Very happy with them.<br

You don't want a trickle charger (unless you're willing to
constantly monitor the battery's state of charge; otherwise
they can overcharge and 'cook' your battery--ask me how I know
;). You want a 'smart charger.'<br clear="none">

There was a time I would have recommended BatteryMinder, but
the last one I bought was lighter than the 3 I'd bought
previously; I think they went solid state over good ol'
transformers, and it hasn't performed well compared to the
older ones. I bought a BM (heh) for AGM (only) 12V
batteries--I have AGMs in my BJ8 and some in yard/farm
equipment--and it's well-made and performs well (in
particular, the cheaper ones have flimsy connectors that often
get chewed-up due to arcing). BatteryTender is the main
competition; I haven't used any but haven't seen any negative
comments on them. Harbor Freight sells one but, again, I have
no experience with it:<br clear="none">

A trickle charger won't turn itself off; the good tenders
monitor the voltage closely and maintain a 'float' charge;
some also have desulfation capability which can sometimes
resurrect a 'dead' battery:<br clear="none">

There are no 'cons' to using a good smart charger--except that
you have to remember to hook them up--used regularly they can
extend the life and usefulness of lead-acid batteries.<br
