Motorcycle cold knowledge: Why does the motorcycle battery fail, and how to maintain it
Release date:2023.11.09

Battery as an essential part of the motorcycle, if used improperly or do not start the car for a long time, then the performance of the battery will decline until it is exhausted. We talk about lead-acid batteries, this is because compared to lithium-ion batteries, or lithium iron phosphate batteries, lead-acid batteries in the market is higher. Whether your motorcycle battery type is maintenance-free or some other type of maintenance-free battery, as long as its electrolyte is acidic, it can be considered a lead-acid type.

PART 01 How does a Motorcycle Battery Work?

1, the electrolyte solution contains charged ions, which are composed of sulfate (negatively charged) and hydrogen (positively charged).

2, add electrical load (such as starting the motor, ECU, headlight), etc., will make sulfate ions transferred to the negative plate of the battery

3, the ions and the active material on the plate react to release electrons

4, these excess electrons are transferred through the negative electrode of the battery to any device connected

5. Electrons return to the battery through the positive electrode

6, the movement of electrons is the direct current of the battery, in amps (A)

7. The electrons then attach themselves to the positive plate.

PART 02 How does a battery discharge?

1, the battery does sulfuric acid decomposition at the same time, which means that the electrolyte becomes less acidic and more water

2. Lead sulfate covers the panels in each battery cell

3. The coated plate has a small surface area to generate electrical energy

4, this causes the generation of current to decrease with time, if the discharge continues, more lead sulfate is deposited on the plate

5. Eventually, the chemical process that produces the current stops; If the battery is severely sulfated, then no matter how long you charge it will not be able to restore its own self-discharge ability.

6, even if you do not connect any load circuit, all batteries will discharge themselves during their actual life.

7, as long as the battery charging state is less than 100%, sulfation will occur

8, the rate of this discharge depends on the type of battery and the ambient temperature, if the battery is undercharged, or continuous discharge for a few days will occur sulfation. Of course, smaller sulfuric acid batteries (such as motorcycle batteries) will also sulfate faster.

9. Storage of batteries higher than 24 degrees also accelerates self-discharge and increases sulfation

PART 03 How to maintain a motorcycle in winter?

Because in the winter, many car friends will leave the vehicle vacant for a long time, the best practice is to remove the battery, and then do phased charging and discharging work; Some riders asked whether the vehicle can be ridden out every once in a while in the winter, or a fire to charge. In fact, this time is not enough, because short trips (within 25-30km), can not generate enough electricity to the battery, and now there are more electronic devices on the motorcycle, so it is easy to produce high power consumption.



Generally speaking, the battery life of the car is generally not more than 4 years, and the decay is serious after 4 years. If you need to maintain your battery, it is best to install a voltmeter on your motorcycle to monitor the charging efficiency and battery condition at any time.

The above is why the battery will fail, and if the maintenance of some tips, you have learned?
