Bike Battery – The Ultimate FAQ Guide

This is your go-to FAQ guide about Bike Batteries. Here, you will find answers to many questions that might come to your mind regarding a Bike Battery.

Have a look!

1. What is a bike battery?

A battery is the main source of electrical energy in the bike just like in all other vehicles. It stores chemical energy.

They are made to power the motor, engine, and other components of the bike.

The headlights, indicators, etc. all are powered by the battery.

The battery is fully charged, and it gives out energy to run the bike.

6. Are bike batteries easily available?

As bikes are more convenient to use for travel in rush hours, not to get stuck in traffic jams, bike batteries are quite in demand as of their use.

The bikes with rechargeable batteries are considered instead of fuel bikes in most of the parts of the world as it creates less pollution, is eco-friendly, and less expensive than fuel-burning ones.

7. What is the life span of a bike battery?

Typically, a bike battery can last for 2 to 3 years which totally depends on the maintenance and care.

Bike batteries of any type will lose their capacity over time even if they are not in use.

Various factors affect the life span of the battery such as:

  • Temperature
  • Charging
  • Maintenance
  • Keeping the battery cool
  • Not to let the battery die completely before charging.

A slight problem in any of these factors can ruin the battery’s longevity.

8. What are the capacities available in bike batteries?

The most used capacities for bike batteries are 24V,36V and 48V If the batteries are in good condition, they are higher in voltages.

You can make the capacities from 10Ah -30Ah as your request.

9. Can you recharge a bike battery at home?

Yes, a bike’s battery can very easily be charged at home just by making sure the voltage to be delivered just as required according to the battery’s capacity.

  • Remove the battery from the bike and connect one side of the charger with the battery terminal and the other one in the wall socket.
  • Keep checking for the battery charging status and remove it as soon as it is fully charged.
  • Install the battery correctly back in the bike.

10. How can you know if your bike battery is dead?

There can be several symptoms that may detect that your battery is dead or cannot be used.

Some of the major symptoms might include:

  • Discoloration of the battery due to the stains from the bike. If a change of colors is seen in a battery depicts it is in the last stages and should be replaced.
  • Swollen batteries or cracks indicate that chemical gas is built up in the battery due to corrosion on the inside. It may also happen due to overcharging or heating up.
  • If a battery does not hold a charge even after immediate charging, this battery is not only dead but also a bad battery.
  • If your bike does not start at all, that means it is surviving on a dead battery. However, there can be various other problems that lead to this and should be properly examined to find the right reason.
  • A symptom of a battery that is about to die is the fading in the headlights of the bike or horn. These indicate that the battery is draining and not providing power as it should.
  • Leaking of the battery acid is also an indication that extreme oxidation is happening inside the battery that may cause an explosion.

11. What type of charger is used to charge a bike battery?

Find out the battery type before selecting a charger for it. Whatever charger you may use for your battery the major consideration should be the matching of voltage.

You can also charge your bike battery with a regular phone charger, but the voltage required by the battery should be checked.

If the battery is of 36 volts, the charger should be of a 54.6 volts battery too otherwise it will ruin the battery’s health and life span.

12. What type of battery is the best to be used in a bike?

The most preferred battery capacity for a bike battery is 24V ,36V or 48V li ion battery. It solely depends on the engine of the battery.

However, lithium-ion batteries carry out the best working in bikes.

They are lighter in weight and ideal for harsh ridings on and off, have a lower discharge rate which makes them last longer, and perform better in cold and hot weather.

Lithium batteries offer the best battery life and less to no maintenance.

Make sure the cakes are connected correctly to avoid any errors.

Guarantee everything is in its place and secured placing the belt provided in the battery sections and put the bike’s seat back in its place.

Following is a link to a tutorial explaining connecting batteries to the bike.

21. What will happen if the terminals are not connected correctly?

Meddling with the terminals can ruin the power source and even lead to an explosion.

The wires will heat up, the battery will be damaged, and it will ruin the electrical components of the battery.

However, in some cases, the battery may work but the polarity will be backward, and no explosion will be created.

It is recommended to go through the user manual before doing such tasks as they can guide very well about the terminals and correct installations.

22. How can you know if a battery is fully charged?

24. Why are lithium batteries better than lead acid for bikes?

Lithium batteries are proved to be better in functioning, are lighter, have a slow discharge rate, long battery life, and good performance in cold temperatures.

The weight is the major plus point of considering lithium batteries as they make it easier to handle a bike.

They also have a low discharge rate that makes it to work longer than usual batteries however, it may reduce with time.

So, lithium batteries are better in working and functionality than lead acid batteries and are worth the high price spent on a good one.

25. Does the battery life affect the working of the bike?

Direct effects will not occur on the bike due to battery malfunctions however, it may cause other systems and components of the bike to run inefficiently and as a result, decrease the performance of the bike as a whole.

26. What is the best temperature for a bike battery?

Driving a battery at superior temperatures improves their performing ability however longer exposures to such temperatures will shorten the battery’s life.

Freezing temperatures increase the resistance of the battery but lower its capacity.

Temperatures below -15° and higher than 45° should be avoided for the battery to carry out effective, long term work.

27. What are the pros of bike batteries?

As every product has its pros and cons, bike batteries have too.

  • Most of the bike batteries require less maintenance.
  • Lithium batteries are lighter in weight.
  • Easy mobility.
  • Can be charged anywhere.
  • Are eco friendly.
