A while ago I purchased a Shumacher 1562A (not the original 1562)
battery minder. I forget the details, but it did not seem to be
supplying the correct voltages. I sent it to Bob K. for
investigation, but I doubt that he has had a chance to look into it.

???? when did you sent it and to what address. I
don't have it in hand.

Anybody using these "Speed Charger" products? What are people using
these days to top off their sealed lead-acid batteries.

I've purchased a number of 1562's over the years. A couple
for personal use and more for customer applications. I've
only plotted the performance of a couple . . . and they
both plotted out like this

Schumacher is an old-line charger house with pretty
good credentials and history. What's your application
and what's your budget?
I have a couple of the gee-whiz processor controlled
chargers . . . haven't plugged on in for years. I think
I reduce the inventory to one and put the others in
the next garage sale. I've got several maintainers
that cover 99% of my charging/maintaining needs. Meaning
I almost never plug in a battery where I need to put it
back in service in less than 24-48 hours . . . so the
itty-bitty wall-wart style devices get the job done.

Bob,
I noted your plotted graph for the 1562 style charger.
How important is it for the charger to top off at the 15v before dropping
down to the 13 volt float range...?
I ask because some of the "itty bitty" lower cost units (Harbor Freight,
etc.) appear to slowly bring the charge up to the 13 volt range and just
float there. Thus, skipping the 'top off' potential. This is referring to
standard or sealed aircraft batteries usage.....
Dave

Hi Bob K.,
I sent the unit to you quite sometime ago maybe spring 2010...I can't recall more exactly. You acknowledged receipt, but I think it was just prior to your workshop move/reorganization. You had warned it would be a while before you could get to it. But, don't worry, no harm done. I'm in need for another unit and am just wondering what I should be getting. Something like the $20, 1 A Shumacher "Speed Charger" unit should be fine for topping off my small Concorde and Odyssey batteries...if the Schumachers are working as they should.

Hmmmm . . . my bad. I've still got some totes to unpack.
These are what one generally refers to as 'chaos boxes",
the final dregs of cleaning off the shelves and benches
but still awaiting storage space to unload them into.
Where are you seeing this "speed charger" offered? Which
model? Just curious. If it's got Schumacher's name on it,
the risks for failure to perform as advertised is low.
By the way, if you're storing multiple batteries on a
charger capable of maintenance operations, you can parallel
a number of batteries on a single maintainer.

Ok, I'll try out another shumacher. I just picked up the "Speed Charge" name from the shumacher website (SC series). I'll see what I find at wall mart or autozone.

Aha! I guess I was out of the loop on Schumacher's
advertising. Seems the whole line of Schumacher
products bear the 'speed charge' label.
I've uploaded some Schumacher user's manuals to
the website at:
http://aeroelectric.com/Mfgr_Data/Battery_Chargers/
Walmart offers several chargers in this line
starting with the 1562 and moving up.
I'll keep an eye open for your 1562 . . . it's
got to be in that pile of stuff somewhere . . .
