I have been a devoted user of both Battery Minder and
Battery Tender products for the charging/maintenance
of wet, svla, and automotive lithium batteries for
decades.
Got a half dozen or more of these things in my
shop. While their charge rate is pedestrian (less
than 1.0A) they DO ultimately top-off a lead-acid
device and subsequently MAINTAIN it indefinitely.
Sadly, my go-to favorites have been creeping up in
price for some time which has prompted me to put
a dip-stick into the emerging market of battery
charger/maintainers.
I've had one of these things for awhile . . .
https://tinyurl.com/3e48emj4
. . . and used it to conduct some battery performance
tests as well as mitigate some battery issues on
my vehicles.
I can report that they do a credible (and much
stronger) job of battery charging compared
to my 'wall warts' (8 amps). They've got some
'features' that presumably favor seasonal
variation in battery performance as well as
a 'pulse repair' mode.
I've not yet confirmed that these 'extra' features are
valuable but I can tell you that the charge/maintenance
modes for wet and SVLA technologies are solid.
I'll have some data plots to share in future but
in the mean time, the current price for this
product is very competitive with the BatteryMinder/
BatteryTender alternatives.
I've also acquired a piece of test equipment
that is of exceptional utility/value . . .
watch this space.

Bob,
Have you taken a look at the Noco chargers? I've used their Genius 5 on my PC680 AGM for some time now, and it seems to do a good jo.

I have been testing similar chargers with good results. It is worth noting that some have a trickle/float mode after the main charge, and some do not. For maintaining a battery, the trickle mode is essential. For one-time charging, no biggy. I wish it was selectable with a switch.

Good find, on Amazon. At least there you can read reviews and after
reading the 1 star reviews, I decided to pass on it.
I have had good luck with the Ctec chargers, personally. But they're
nowhere near the price.

Yes. All batteries are plagued with a self-discharge
characteristic will ultimately bring stored energy
down to a level that promotes internal destruction
of the chemistry.
It would be interesting to know your experience
with the various products.
The ideal charger has a MAINTENANCE mode that supports
the battery's terminals to a voltage just above the
open circuit voltage. Well maintained batteries on
my bench present an O.C. voltage on the order of 12.9
volts. My maintainers support shelved batteries at 13.2
to 13.5 volts. Just enough to support self discharge
currents but not enough to ADD energy to the chemistry
thus leading to overcharge.
The original concept of a 'trickle' charge was to
constantly push some small charge current into the
battery . . . say 100 mA or so. But I've seen legacy
trickle chargers that put out 500 mA or more.
Yeah, they prevented self discharge but eventually
cooked the battery.
| Quote: | For maintaining a battery, the trickle mode is essential.

The charger I cited has a mode select switch that
claims to differentiate between wet and SLVA devices.
Not sure the physics really supports such an idea
but I'll continue to exercised this product and
gather more data.
Unlike the 'wall wart' devices, this one is a REAL
charger having an 8A rate at 12v and 4A rate at
24v. Further, it tapers down sharply at some
plateau and enters a 'top off' mode of approx
2 hours at something on the order of 1A with a
cutoff that appears to be about 0.8A.
I've got a plot of this behavior which I'll go
get later this morning (need to see up file
sharing over the WiFi to replace data-transfer-via-
thumbdrive!)
The important thing is that if you load a battery
under maintenance for a few seconds, the charger
reverts to a top-off mode and replaces expended
energy.
This behavior is consistent with a true MAINTAINER
as opposed to the legacy open-loop, trickle charge
philosophy of yesteryear.
I'm setting up a new test facility out in the
mess-making shop to explore the physics of things
like batteries, chargers and small alternators.
Will update the List as new information is secured.
I've got a couple of group 4, 100AH batteries on the
shelf that I've been storing for a client who seems to
have abandoned the goals for having purchased the
batteries.
They are new, old stock, sustained on maintainers for
about three years. I'm interested in seeing what
shape these batteries are in for having sat so
long! Need to finish my 50A discharge adapter
for the WestMountain CBA.

The NOCOs are way overpriced. Bob's example does a better job at 1/6th the price.
Bob, have you found a similar charger for lithium batteries?

Good find, on Amazon. At least there you can read reviews
and after reading the 1 star reviews, I decided to pass on it. |
The 1-star comments are often problematic.
OFTEN short on DATA that promotes meaningful
analysis. One such review blamed a near-miss
house fire on the charger. He included a photo
of an extension cord powering the charter where
heating effects caused catastrophic damage to
the cord's receptacle.
Joints at connectors always fail in the female
pin . . . that's were pressure good conductivity
is maintained on the mated members. This charger
puts out about 100W when puffing hard to charge
a battery. Even at 50% efficiency, input current
to the charger would be on the order of 1.6A.
For destruction to have occurred at that current
level suggests a severely compromised receptacle
on the end of the cord.
Read another 1-star beef complaining that the
charger would not pick up the task on a 24v
battery discharged to less than 10V. Of course
the smart charger deduced this to be a 12v battery
and 'topped it off' at 14.5 volts! It pays to
read the instructions.
To be sure, there are MANY battery maintenance
products out there with satisfactory performance.
I'm sure that BatteryTenders and BatteryMinders
have worthy competitors for performance.
But there is no analog to Consumer's Report on
battery maintenance products so we're kinda stuck
with LEARNED reviews of a few products by COGNIZANT
OBSERVERS.
So thank you Tim . . . and any others who care
to search around in the marketplace for good
value.
Here's the 'first look' plot I promised on the charger's
performance:

The unit linked below is for 220/240 volt input.
