Looking for a couple of good smart chargers

Elecraft referred me to W3FPR's web page which then referred me to A&A Engineering
whose web site is now plastered with "all products have been discontinued".
Can anyone recommend something equivalent to the old A&A products that might be an
improvement in both engineering & quality ? If they were still available I would buy
one of the 1 A and one of the 5 A.

Thanks for any leads,
Doug W5JV/NNN0BXX

Doug,

The owner of A&A Engineering is trying to retire. I suggest you look at
the offerings that go by the name of 'Battery Tender' for good 3 state
chargers.

I forgot to mention that the 'Battery Tender' also needs a direct
connection to the battery, so the mod to the K2 is still valid. See my
Smartcharger article on my website www.w3fpr.com for details on the
direct battery connection. Fusing the direct battery connection is
mandatory for safety, install the fuse inside the K2.

I don't know about, "an improvement in both engineering and quality", as I never
faulted A&A for either.

That said, I know that my suggestion isn't what you're after for the moment but
if you or others ever need higher current "smart chargers", look at Iota
Engineering's products. I've replaced some RV RFI-generating battery chargers
with Iota and found them to be not only better for the batteries, but
essentially free from RFI.

I have used two different units of the Battery Tender 6A charger model.
One failed (after many years) leading to overvoltage. The other
generates huge amounts of RFI especially on 20m. They certainly seem
smostly ok, with those caveats.

I recently got an Optimate 3+, which is only 600 mA but claims to do
desulphating. Notably, when going into float mode, it float charges for
30m and then lets the battery sit for 30m, which seems nicer to the
battery, and also lets it detect more cases of batteries that are not
ok. RFI-wise it seems not as bad but hardly ok.

I also have a gensun gv-5 MPPT solar controller. It and a panel makes
an RFI-quiet charger, at least on some days. It floats at 13.5V, nd
does equalization at 14.2ish once every 7 days.

These are good units. I have a GV-10 controller for lead acid that is
dead quiet. They have models for different battery types and voltages.

Whichever one you decide on, I'd strongly suggest you get something,
otherwise the battery will need a a LOT of attention. I have the A&A
smart charger and it works like a charm with zero attention to it.
