The motorcycle battery voltage rating should be at least 12 volts. It can also be as high as 14 or 15 volts if you have heavy-duty use from time to time. The size of the battery depends on how much power your lights will draw and other uses that it has. If it’s used only for lights, then a small battery (12V) would do just fine. But if it’ll run an electric starter, alternator, etc., then a larger one might be needed.
If you’re not sure what kind of battery to buy, get some advice from someone who knows about motorcycles before buying. Also, make sure that batteries are fully charged when purchased so they’re ready to go. When possible, get batteries online instead of at a dealership because most dealerships charge extra fees for this service.
A motorcycle battery has two terminals. One terminal is positive (+) and the other is negative (-). The + terminal is connected to the ignition switch and the – terminal is connected to the starter motor.
The voltage of a motorcycle battery is 12 volts DC (V). This means that the battery provides 12 V of power to the starter motor. If the battery is fully charged, then the voltage should read 12 V.
The voltage can also drop when the battery is not in use or when it’s being recharged. When the engine is running, the alternator creates electricity from the kinetic energy of the moving parts. This electricity is stored in the battery and used when needed.
When the battery becomes empty and the voltage drops as the battery discharges. As the battery gets closer to zero volts, the battery may stop working completely. Once the battery reaches a certain level of discharge, it won’t recharge properly again. Therefore, it’s important to keep the battery charged.
You can test whether the battery is charging or discharging by using a voltmeter or multimeter. Turn the key on and check the voltage between the 2 terminals (positive & negative terminals). A typical modern motorcycle battery starts out with 12 volts. After the battery is fully discharged, it will start to drop until it hits 10 volts. As soon as the bike starts up, the voltage should rise back towards 12 volts. As long as there is sufficient charge left in the battery, the voltage will keep rising after the engine starts running.
A 12v motorcycle battery can last up to 2 years on average. It would depend on the amount of time spent charging it, as well as a few other things. Batteries do not keep their maximum charge indefinitely; it’s just simply how they work. There isn’t necessarily anything wrong when your battery gets low.

How long does it take to charge a 12V motorcycle battery?
Depending on the type and condition of your battery, it could range anywhere from 3-4 hours to 24 hours. Some people claim that a new battery takes longer to charge than an old one. However, I’ve never seen any proof of this claim. If you don’t want to wait that long, you could always swap out an old battery for a new one. Make sure the replacement battery has been fully charged first. You should also check the connector where the battery connects to the starter, especially if the original connection was loose. Loose connections can cause problems like yours. Keep in mind that even though your battery is fully charged, it still needs periodic maintenance to prevent corrosion. It only takes about 5 minutes to install a new battery. Just make sure you have a good quality battery installed before you go riding.
The biggest factor affecting how long it takes to charge depends on the age of the battery. A well-maintained battery will provide power quicker than a poorly maintained one. There are two main reasons why a battery can lose its charge so quickly: Overloading – Overloading causes excessive heat inside the battery which reduces the electrolyte solution and degrades the battery pack. Charging too quickly – Charging too fast causes excessive heating inside the battery which reduces its ability to hold current. Once the battery overheats, the internal resistance increases and the current drops dramatically. This causes the battery to discharge much more slowly.
It depends on many factors: Battery type, state of charge, number of cells/batteries in series, the voltage of battery terminals prior to connecting the battery charger, etc. You need to find out exactly what those variables are and figure them into the equation first. Then you can determine the approximate amount of time necessary to charge a given battery. Most electronic devices require at least 4 hrs of constant use to fully charge a Lithium-Ion Battery although some can be charged faster under “boost” conditions.

How long should a 12-volt battery hold a charge?
A 12V battery can hold a charge for up to one month or even two months. if it is fully charged before use. Old batteries will go flat much faster than new ones. If you leave your bike outside for long periods, we recommend that you remove the battery from it. If you connect a battery that has been fully charged while connected to your bike, it may occasionally cause issues with its electronic components.
Battery charging time depends on the type of battery and how much current you draw from it. The more current you draw, the faster the battery will be drained.
The battery also powers other electrical accessories like headlights, windshield wipers, heater blower motors, etc. These accessories do not require a lot of currents so they don’t drain the battery very quickly.
When the battery is completely discharged it takes several hours to recharge it. You may want to keep a spare battery available just in case your main battery needs recharging.
You can test the state of your battery by using a multimeter. It is best to test the voltage and discharge rate of the battery. The voltage reading tells you whether it is a good or bad battery. The discharge rate indicates how fast the battery is being depleted.
If there is no voltage drop when you connect the meter leads to the terminals, then the battery is fine. If there is a noticeable drop in voltage, then the battery is probably damaged and should be replaced immediately.
Batteries have a limited life span and once they get old, they start losing their capacity. They may become weak and unable to deliver enough current to run all the electronics and accessories on your vehicle.
Good maintenance helps increase the lifespan of the battery. However, if you overcharge the battery, then it might catch fire and burn. So, make sure that you know how to properly maintain your battery.
