Battery in my yard tractor is acting screwy. I cleaned all the posts.
Checked for low water in the cells (they were not low). Then I
charged it to full charge, leaving the 10A charger on for a full day.
It showed fully charged when I removed the charger. The tractor
started. I ran it for about 10 minutes and shut it off. An hour later
it would not start, only clicked the solenoid. I had not left the
ignition on nor the lights. I put he charger back on and it showed
about 5 amps on the charge meter. I left it charge for about 2 hours
and the tractor started again. I only moved it so it only ran about 2
minutes. A half hour later I tried to start it again and it would not
turn over. I began to think there is something draining the battery,
so I took off the NEG cable, and charged again. This time it charged
all night. The next day it started. I only ran it for a minute to
check it and shut off. This time I removed that NEG cable again, so
nothing could possibly drain it. A few hours later I tried to start
it, and again the battery is nearly dead.

This eliminates anything draining it, and it was fully charged. Does
this mean there is an internal short in the battery? Otherwise, where
is the power going? Either way, it's looks like its time for a new
battery, but normally they dont take a charge when they die. This one
charges, starts the engine if I use it right away (with charger
disconnected), yet in a hour or so, it's dead. I cant say I ever seen
a situation like this before.

By the way, the battery is only about 2 years old, but it's from
Walmart, and their car batteries have proven to be the worst batteries
I have ever used, so I dont doubt these tractor ones are from the same
manufacturer.

Hi,
First of all, how old is the battery? To check if something is drawing
durrent when engine is shut off, you put a little 12V bulb in series
with battery cable. If it lights up, that's trouble.
I think your battery is shot(internal short most likely) if you keep
trying to use it, you may damage the charging circuit component(s).
What is the voltage when it is fully charged? What is charging voltage?

Walmart, and their car batteries have proven to be the worst batteries

I can't speak to the quality of Wally World batteries.

I suggest you do have a "battery drain" which is discharging it. Your
battery may have been damaged by being left in a seriously discharged
condition for a good time.

IOW: you have two problems.

You didn't say (or I missed) whether this is just a garden tractor or a farm
tractor or whether this is a "car/truck" battery or a motorcylcle battery.
But you can do simple "stand alone" battery tests where you charge it on a
bench and monitor the voltage while putting it to a moderate load (like some
lights, etc.) and then check it for self discharge. My guess, however, is
that it's toast.

If you don't have one already get a cheap VOM (Volt Ohm Multimeter) and with
the battery disconnected you can use the resistance function to see if there
is a discharge path with everything off. With the battery partyly
connected you can see if there is any leakage. Be careful here as you
can easily ZAP your meter. Try a high current scale first and then work
down. Don't do anything silly like turn on the lights while you have the
meter on a high sensitivity current scale.

At the other extreme it's possible that you have damaged your battery by
overcharging. A lawn tractor doesn't have a particularly sophiscated
charging circuit. When the battery is being charged the maximum voltage
should be 13.2 volts or less. When a charged battery is under no load but
not being charged the voltage should be 12.6.

But if I were better money I would say that a new battery would solve most
of your problems. If you suspect a current drain, still a quick disconnect
for your battery and use when you put the machine away at the end of the
day. If you suspect over charging, leave the light on even during the day
when you run the tractor.

You likely need a new battery. I bet you leave that tractor stored
each winter for months with no charger. Two years sound about right
for a cheap battery under those conditions.

Pretty simple. If you charge a battery up, leave it disconnected, and
it's dead a couple days later, the battery is kaput.

I agree with the above too. If you don't put a battery tender on a
battey and instead just leave it over the winter, a couple years life
is not unusual.

The symptoms you described are not unusual for a bad battery. Holding
a charge for only a short length of time, sometimes only a few
minutes, is a very common failure.

This frequently happens in the Spring and Fall when the temperature is
changing. It's due to the resistance of a microscopic layer of oxide on
the terminals. You must remove the wires and brush with a battery
terminal brush, both inside and outside. Put the terminals back
together with a grease-coated felt washer under each and cover the
terminals with some grease to seal out the air.

As others have said the battery is probably dead from having set too
long without being charged.

My lawn tractor sits all winter in the shed (around here, about 5
months). It fires right up in the spring. I don't charge it over the
winter. It's going on 7 years and still has the original battery.

I agree with most of the other posters that your Walmart battery is most
likly toast.
You should be aware that most these batteries should not be exposed to a
charge of 10 amps. Even when new, the shop will give it a zap to help along
the "dry charge" It is claimed that this and other instances of 10 amp
charge will shorten the life of the battery.
2 amp charging is recommended by the makers of most of these small
batteries. The battery tender is the best way to maintain top charge.

The test is to charge the battery with one or both battery cables
unhooked. Leave the battery still unhooked, overnight. If the tractor
won't start in the morning (remember to reconnect the cable) then
replace the battery.

His lead-acid battery is probably sulfated and not capable of being charged
properly.

Vector makes chargers that allegedly desulfate and recondition L-A
batteries,but I've not tried them myself.
The charger would cost more than a new battery,that is certain.

Of course,you could buy a Vector charger,try it,and sell it on Ebay as
bearely used if you aren't satisfied with its desulfating results.

Yes, your old battery is probably bad, especially after being on charge
all night at 10A. BTW, a 10A automatic charger won't fully charge a U1
(lawn tractor) sized battery. It builds a float charge too quickly, and
starts pulsing on and off. Those pulses can be worse for the battery
than the 10A cooking.

An electric PTO clutch can kill a battery in less than 30 minutes if the
charging circuit in the engine has failed, or wasn't sized properly by a
cheap manufacturer who ordered a low power alternator to save money.
Also, if the charging circuit has failed on a cheaper machine, the
alternator could be killing your battery. Most do not disconnect the
alternator through the switch, but wire it directly to the battery lead
at the solenoid.

Desulphation chargers give a high voltage for a time to break down the
sulphation they should not be too expensive try www.batteryworld.co.uk

While my name appears below, I sure can't say as I've written any of

Desulphation chargers give a high voltage for a time to break down the
sulphation they should not be too expensive try www.batteryworld.co.uk

This does not always work. The sulfation can break down in only a
localized area of one or more cells, and within a cell where the sulfation
reversal gets concentrated into a "hot spot" that cell effectively becomes
a tiny repaired one connected in parallel with the sulfated remainder
that will not de-sulfate when the localized repaired region holds down the
voltage across that cell.

I have tried high voltage on sulfated lead acid batteries. This is a
well-known trick that is well-known to only sometimes work. In my
experience, this does sometimes work.
Also, batteries have limited life no matter what you do to them. If a
battery has several years of having been in existence of being a battery
or a possibly ex-battery, I would think that a repair has little value
even if it is successful - the battery is likely to croak more surely
sooner rather than later after a "repair" done when it is several years
old. I would chalk up such a battery as an ex-battery and, if it is
lead-acid, dump it onto the outgoing dead battery heap at an auto parts
store (with permission from someone who woirks there).

Another thing to keep in mind: Age of car batteries that have
warranties. Plenty gets spouted that car batteries have a high rate of
only minimally outlasting their warranties, and that some of those
warranties are pro-rated - to give small fractional remediation if the
battery expires a few months or a year before its warranty does!
So if your 6-year battery is successfully repaired from a sulfation that
occurred at 6.5 years, plan on its remaining good months to be numbered!
