Last year I bought a Vector battery charger, the blue "marine" model that
has 2/10/20/35 amp charge rates, and I've used it a couple of times to
charge my tractor battery, car battery and boat batteries. It works well
as a charger at the 2/10/20 rates. Never tried the 35 amp rate.

But the charger also "reconditions" batteries, or so the advertising and
manual say, using a 24-hour cycle to desulfate battery plates. I've never
used this feature, but I loaned the charger to a buddy and he reports that
it actually revived two batteries he was about to toss. I don't have any
other details.

My one gripe about the charger is that its LED readouts are virtually
impossible to read outdoors, even in indirect light.

I got one of the small ones and liked it so much I got the bigger one with
up to 40 amps charge rate and a 100 amp "start engine" setting. Like you, I
revived a couple of motorcycle batteries that sat all winter and would not
take a charge with a regular charger.

Unfortunately, after using it maybe 6 times the bigger one died. Plugged it
in one day and it went "pop" and a small trail of smoke rose out of it.
The little one still works but you have to slap it around to get the fan
running. They are great chargers but I am not so sure about the quality.

Why not just buy a new battery? I personally don't want to take any
chances. If a battery goes dead, why risk your peace of mind and safety for
maybe another 10% to 20% of its normal life?

I agree with you if the battery is a few years old however sometimes a
battery in perfectly good condition can sulfate over during a period of none
use, as is my example of the motorcycle batteries. When the plates sulfate
and you try to charge the battery, it will quickly come up to the charger's
output voltage and the current drops off as if it is fully charged. The
problem is that the battery is far from fully charged, it is just displaying
a surface charge, acting like it's a very small battery. When you put a
real load on the battery, the charge quickly dissipates and there's no
juice.

The "reconditioning" feature on these chargers output a much higher
voltage - typically in excess of 15 volts that overcomes the insulating
properties of the sulfated plates and "burns" it off. A battery that was
not allowing any current from the charger before reconditioning will now
take a normal charge. I've done this several times in the past with the
motorcycle batteries and once regaining a charge, the battery is fine for
another season of riding.

I remember years ago there was a battery additive marketed that chemically
did the same thing and was supposed to bring dead batteries "back to life".

Interesting. Thanks for the explanation.

BTW ... the "reconditioning" mode on these chargers do not supply a steady
voltage. It pulses on and off at a programmed frequency to help burn off
the insulating layer on the plates. There's another term for doing this
that is commonly used other than "reconditioning" but I'll be dipped if I
can remember what it is at the moment.

Hi Eisboch,

Another term is "pulse charging". Equalization charging can be used
to also clean up some sulfation on wet and some AGM VRLA batteries.
For more information on sulfation, please see Section 16 in the Car
and Deep Cycle Battery FAQ on www.batteryfaq.org and for charging and
chargers, Section 9.

BTW, Vector was purchased by Black and Decker a couple of months ago.

Kindest regards,

BiLL.......
