I have an older x2001 quadloop that I replaced the battery on this year. I am using this on a property where I only mow every three weeks. The new battery discharges completely over a 3 week period and is measuring 0 volts. Mower will start with a jump box and shows 15 volts while charging. The mower will start fine the rest of the day but the battery will be dead again 3 weeks later. I guess I could have gotten a dud battery or I have developed some sort of parasitic draw. Has anyone experienced this or have any troubleshooting tips to share? Thanks!

A couple options here.

1> Disconnect the fully charged battery and check in three weeks.
2> or better disconnect the battery install an amp meter and check current draw while the ignition switch is off.

Also the model and spec number of the engine will help to look up the charging system but they did come with Kohler 20 hp engine. Most likely a CV20 but the numbers will tell what charging system it used.

Most alternators or charging coils will never properly charge a battery. One crank of the engine and the reserve gets depleted. Sure you might see 15 volts but how many amps? That is where most are deficient.

Put it on a real charger like a Battery Tender brand. That way it's fully topped off when you need it.

Also take the suspect battery to any auto parts store. They will test for free.
