List member Steve Stearns has donated an
excellent candidate for evaluating performance
of a new BatteryMinder Plus that claims to
include 'de-sulfation' technology. The nameplate
rating is 20 a.h. and claims to be a 'deep
cycle' device.
I benchmarked Steve's battery and collected
the following data plot:
[img]cid:.0[/img]
I'll put it on the BatteryMinder's maintenance mode and see what the critter looks
like in about 60 days. Watch this space.

Hi, Bob
Could you explain your graph a bit for me .. I am confused by the caption "9Volt, 15Sec, 120A" - and the top line "5.0A Discharge" - are you discharging at 120A for 15 seconds, or to 9Volts ? and why does the graph/test end at 10,5v ? OR - is the test at a calibrated 5.0A 'till 10,5v ?

That's the data-gathering shorthand . . .
First discharge was 5A constant current
which produced the green plot and
shows energy content in the battery
as it arrived here.
The other two plots were taken after
a legacy constant current/constant voltage
recharge with top-off interval.
A after a third recharge, I did a load
test where the battery was loaded to
9 volts for 15 seconds after which the
current being delivered was 120 amps.
It only took a few minutes back on the
charger to top it off again.
At that point, I put it on the BatteryMinder+
in the 'maintenance' mode. I'm getting
some data gathered on this particular
product's electrical 'pixie dust' purported
to 'de-sulfate' the battery.
I'll publish pictures of first observations
in a day or so . . . as soon as I get about 4
computers polished up and out of here . . .
Speaking of things to do . . . see attached
photo. I probably won't be working on the
pickup just visible past the left edge of
the building. Had some frog-strangler rains
up north a few days ago. Medicine River just
west of town came out of the banks and flooded
a mechanic's shop where a friend of mine had
taken his pickup truck for some routine maintenance.
Hard to see in photo but water is up to window
sills on Kenton's truck. There are numerous
pieces of heavy equipment parked around this shop
in similar predicaments. I only attached photo
instead of embedding. Any digest subscribers
have problems seeing this image?

I can see the picture just fine on the Matronics website.

Usually a flooded vehicle is considered to be totaled because the wires and connections become corroded.

I get individual emails; I got the image on my phone as an attachment. (Sometimes I see different behavior depending on whether I'm viewing on phone or computer.)
