Just wondering how many seasons or months you guys are getting out of your rider mower batteries. My Cub is just at two years old and the battery is starting to go south. Mower wouldn't start last weekend without help from a charger, that was after not being used for about three weeks. I checked the voltage the day after I mowed and it was at 12.7 but today, 5 days later, it was down to 12.3 and would barely start the mower.

Charge fully overnight then start. Measure battery voltage while running.

4 years on the original MTD battery on my TroyBilt. Stopped holding a charge last week.

If you don't keep a maintainer on it over the winter, 1-2 years is typical. With a maintainer, 3-5 years is attainable.

A good maintainer over the winter helps you get several years.

12.3v and barely starting the motor? Sounds like your losing a cell. What brand?

I just bought a Wall Mart battery for my lawn tractor replacing an identical battery after only 2 years. I noticed they are being made in Columbia.The Johnson Control walmart battery of the same age on another machine is still going strong.

A coworker recently had the battery go dead on his rider between cuts. He noticed that he had stacked something on the seat during that time, and the only thing we can figure is that the ignition circuit was energized by the weight on the seat activating the seat safety switch. I wouldn't think it would matter if the key were off, but that's the only thing that remotely makes sense.

Just something else to think about.

No long at all. I use one to power a drywasher. I have had 2 or 3 go bad even with a maintainer on it.

They only have a 6 month warranty on them because few people use maintenance chargers to keep them charged properly.

Mowers with electric blade clutches have a somewhat real electrical / charging system with a voltage regulator. Those without usually only have an unregulated charging coil which can over or under charge.

I think another cause of short life is the vibration a mower battery receives.

My first one lasted 4 years, then I got an Odyssey PC 625 and it's never had a problem since for the last 14 years. I don't even need to boost it in the spring.

Thanks guys. I think I try to finish out this season then replace it next year. I might even do what I do with the old Pontiac's battery. Every winter, it stays disconnected and hooked to a charger that is on a wall timer set to come on for 1 hour a day.

I fully charged it last weekend when it wouldn't start and tested when running at 14.1v

I don't use a maintainer but do charge the battery once a month during the winter. The mower was stored in my workshop which never drops below 40 degrees

It says MTD products, made in USA, no other name.

My yard is one acre and pretty rough. My wife also took care of the next door neighbor's acre so it could have been beaten to death.
