L130 battery issue

[chicken]

Hey,
I recently purchased a larger property that came with a John Deere L110 and L130 (one used as a lawn mower and the other used as a snow remover).

The lawn mower (L130) doesn't seem to charge the battery while running and just drains it. I have to jump start the lawn mower every time I want to get it going, I've even switched batteries with the L110 (which i'm quite sure has a decent battery) but I still need to jump start the lawn mower to get it going.

Any ideas on what the issue could be?

Take the battery in for a test, and likely will need to buy a new one. Maybe even for both.

Thanks for the welcome!

I guess I should give that a go when it stops raining and give it another go with a fresh battery from the store.

I was wondering, how long do the batteries last for usually? We purchased one of the batteries three years ago.

On my L130 I have to replace the battery every two or three years, these small batteries don't last long. I use NAPA batteries that are about $30 bucks so figure 10 to 12 bucks a year more or less. You may find a battery that lasts longer but I doubt it would be cost effective.

You should be able to test your battery at no cost, also if you have a test meter you could check the voltage to see if it is charging or not.

ive had my battery in my L110 since new 8yrs i refill cells and charge it every fall

what do you use to refill and charge the battery?

 

[rousch99]

distilled water and 1 asprin per cell. Dont ask about asprin a old old timer told me this years ago seems to work and asprins cheaper then battires

Make sure you have a good battery. while running check the voltage at the battery terminals. should be 13 to 14.5 volts. if not the charging system is not working and is most likely a bad voltage regulator which should look a small square box on the side of the engine with 3 wires coming out of it. two may be yellow in color.

HOW DO YOU KNOW ITS YOUR VOLTAGE REGULATOR....

I have the same problem - it does not charge the battery. My old G100 had the same battery for 6 years. It's a dry cell, so there's no water to add. Suggestions?

HOW DO YOU KNOW ITS YOUR VOLTAGE REGULATOR....

With the mower turned off, unplug the single wire coming off the voltage regulator, and check the voltage. Should be battery voltage. If not then there is a problem between the voltage regulator wire and the battery. Unplug the double connector off the voltage regulator, and start the mower.. with the engine running at full RPM, connect the leads to the two wires in the double connector coming out from underneath the blower housing, voltage will be AC, and should be in the range of 28-32 V. If those two test come out OK, then replace the voltage regulator.

If the voltage is low from the stator (wires coming out from underneath the blower housing) then you will need to replace the stator. It is under the flywheel.
