Moped Battery

A completely flat motor scooter battery can take as long as 20 hours to fully recharge. However, a battery that has lost only a fraction of its charge will take significantly less time, more like 3 to 7 hours to make a full recharge. You can tell exactly how much charge your battery has by using a voltmeter. Monster Scooter Parts has a wide range of electric scooter battery packs; from 12 volt electric scooter batteries to 24 volt, 36 volt, and 48 volt electric scooter battery packs. Our 12 volt electric scooter batteries are compatible with all models of electric scooters, go karts, dirt bikes, and even mobility scooters.

All gas powered Motor Scooters and mopeds are fitted with a battery which is crucial starting the engine due the electric starter motor. However, scooter batteries are small and sadly they won’t last forever despite being charged up as the scooter is driven. But how long does a motor scooter battery actually last for before it needs replacing?


The answer is between 2 and 3 years if well cared for and stored properly during resting periods like over the winter. While scooter batteries can be recharged, as a battery reaches the end of its practical lifespan, normally after 24 months or so, it will lose charge quickly and become unable to hold a charge, a replacement battery will be required.

In this article, I will outline a few ways you can maximise the lifespan of your motor scooter battery and explain how to replace the battery when the time comes.

How To Maximise The Lifespan Of Your Motor Scooter Battery

There are certain measures you can take to prolong the life of your battery to make sure it reaches its 2-3 year lifespan.

The best way to do this is to ensure your battery is fully charged as often as possible.

Constantly allowing your battery to sit and drain, requiring a full recharge, is a sure-fire way to kill your battery.

Therefore, if you are planning on leaving your motor scooter or moped to sit for a prolonged time period, it is essential that you detach the battery and recharge it fully.

You should not leave your battery connected to your motor scooter while it is sitting, over the winter for example, as this will drain the battery fully.

I would suggest leaving your battery fully charged and disconnected when you’re not planning on riding in order to extend the life of your battery for as long as possible.

Your battery will have come with a maintenance guide which will provide you with specific maintenance techniques to prolong the life of your battery.

Be sure to follow the maintenance guide for tips specific to your battery.

How To Recharge Your Motor Scooter Battery

The process of recharging your battery is simple, providing you have the correct equipment and tools and so in the correct manner.

If you require guidance to complete a motor scooter or battery recharge then take a look at this step by step guide I recently put together.

How To Determine When Your Motor Scooter Battery Needs Replacing

When the time comes to purchase a new battery and replace your dying battery there are indicators which will signal a change is needed.

When a battery reaches the end of its useful life, it will be unable to hold a charge meaning that even if you recharge the battery it will be unable to start your motor scooter or moped.

However, you don’t have to wait until the day your battery is unable to start your motor scooter or moped, there are some traits that will indicate the battery is on its way out.

The main trait to look out for is when your battery is reaching its critical level.

The critical level of charge storage is the minimum amount of charge required for a motor scooter battery to start up the vehicle.

One sign which could indicate that your battery is approaching its critical level is if your motor scooter starts up slower than usual even after charging up your battery.

If it seems like your motor scooter is struggling to start up with a fully charged battery correctly fitted, this could be a sign that your battery is weak and will soon need replacing.

Checking your battery for signs of corrosion on the battery terminals is another sign that your battery may need replacing as this is a symptom of worn out batteries.

The best way of knowing when your battery is on the verge of needing replacing is to measure the capacity in Cold Crank Amps (CCA).

All repair shops will have the tools to measure this reading if you do not possess a battery tester, the process is known as an AVR test.

The recorded CCA reading is compared to the batteries CCA rating and if the result falls below or close to your CCA rating, a new battery is required.

How To Replace A Motor Scooter Battery

If your battery needs replacing completely and a recharge alone will not allow your motor scooter or moped to start, you’ll need to remove the existing battery and refit a brand new one.

Changing your motor scooter battery is a simple process:

Locate your battery:

First you’ll need to find your battery. In most cases a motor scooter or moped battery is located under the floor panels, simply remove them and the plastic covering to gain access to your dead battery.

Removing the dead battery:

Once you’ve accessed the battery, locate the black (negative) battery terminal first, unclip the adjoining cable from this terminal first.

Then, you will need to do the same with your red (positive) battery terminal. Unclip the remaining cable to disconnect the battery from the vehicle.

Remove your dead battery carefully, being sure it is not screwed into the frame of your motor scooter.

Leave the old battery down in a safe place, away from excessive heat sources or damp places. You will be able to take it to be recycled at a later time.

Fitting your new battery:

Once you have got your hands on a new and fully charged battery which matches the specifications of your motor scooter or moped, you can connect it in the following manner.

Place and secure the new battery in the designated space under your floor panels.

Start by connecting first the red (positive) cable to the positive power terminal. It should clip into place nicely though you may need a screwdriver to tighten up the terminals.

Then, do the same with your black (negative) cable, secure it in place so it won’t fall off.

Your new battery should now be connected, you can test this by attempting to start your motor scooter or moped. If the motor scooter starts up then your new battery is connected.

If your vehicle fails to start check the connections and the charge of your battery (if you have a voltmeter).

Remember to dispose of your old battery at proper battery disposal site. Most repair shops will handle this process for you and some auto stores handle the process for free.
