Hello everyone.
I’m Nakazawa in charge of service. It’s getting colder and colder. When it gets cold, there are many inquiries that the battery is dead.
Here’s what’s causing your battery to drain and what you can do about it.

1. Cause of a dead battery

Battery drain means “The battery’s power consumption exceeds the amount of charge, causing the battery to run out of power.”.

In the case of farm equipment, most of the electric power is consumed by the cell motor when starting the engine. When you start the engine, it consumes a lot of battery power, so if you don’t charge enough, the battery will go dead. In addition, the battery is always self-discharging, so even if you don’t start the engine for an extended period of time, the battery will run out.

Also, in winter, the battery tends to run out. The battery discharges and recharges by chemical reaction, but when it gets cold, this reaction cannot be performed well. As a result, the battery tends to drain.

2. How to prevent battery drain

The quickest way is to start the engine of the farm equipment regularly and charge it. It is good to start the engine for about 30 minutes and leave it.
But it’s hard to start the engine every day. In that case, I recommend you to use a battery charger.

You can recharge your farm equipment by connecting it to an outlet from a home power source and attaching it to your farm equipment. If you connect it the day before you want to use it, you won’t be unable to start the engine when you use it.

3. When charging does not work

However, if the battery is low, or if the battery is completely discharged due to aging deterioration, this method will prevent the engine from running, so check the battery level regularly and replace the battery if it has been years since the replacement. The battery life is said to be about 4 to 5 years.

4. If the battery does not work even after replacement

If it doesn’t work even after replacing the battery, it may be caused by something other than the battery.

• Check if the battery terminal is loose or disconnected.
• Is the terminal part corroded?

There are other things you can think of, so it would be better to see a nearby farm equipment store. Noukinavi also introduces you to a farm equipment shop that can repair. Please let me know if you need any help.
