A healthy 12 volt battery should ideally register around 12.7-12.8 volts at rest, but anywhere between 12.5-13.5 volts indicates a serviceable battery. Once a battery drops below 12.4 volts, your bike will struggle to start, and at under 11.8 volts, 12 volt batteries are considered to be dead.
Are motorcycles 12v or 6v?
Most of the motorcycle batteries are the conventional ‘lead-acid’ batteries. These batteries can be either of 6 volts or 12 volts. If the batteries are in good condition, then the actual value of voltages isn’t these values. When the battery is charged fully, and it’s at peak, the terminal voltage of each cell is 2.1V.
How do you start a motorcycle with a dead battery?
How to Push Start a Motorcycle with a Dead Battery
- Insert your key and turn the ignition on (make sure the engine kill switch is also on).
- Put the bike into second gear, this will help prevent the bike from jerking when it starts.
- You will need to get the bike moving to at least 5MPH or 8KMH so pull in the clutch while seated on the bike and have your friends push.

How many volts does it take to start an engine?
Therefore, you should always keep your batteries properly charged. With a working generator and engine, they should normally operate at 13,7-14,2 volts. The higher level can overload the equipment, while significantly lower voltage is not enough for a full charge.
How many volts is a motorcycle?
12-volt batteries supply useful energy only through a limited range — from over 14 volts (when fully charged and unrested) down to 10.5 volts in use/under load (when lights dim, your motorcycle is hard to start). No 12-volt battery will remain at over 14 volts for more than seconds unless it’s being charged.
How many amps does a 12v motorcycle battery have?
Depending on the bike the performance capacity should range between 2 to 36 Amp/hour and it can be either 6 or 12 Volt. CCA(Cold Cranking Amperes) can range from 30 to 540A.
What should a 12v motorcycle battery read?
A healthy 12 volt motorcycle battery should maintain a range from 9.5 – 10.5 volts under the load for a good 30 seconds straight. If the battery begins to hold and then steadily drops in voltage, there is a problem. If the voltage instantly drops to 0 volts, that is also a problem. We call this the open cell.
Can a dead motorcycle battery be recharged?
If you do have a dead battery, you can recharge it with a battery charger (this is preferred), or by jumpstarting your bike with another bike or a car.
Is it bad to push start a motorcycle?
No, it won’t hurt the bike. It puts stress on the tires, wheels, chain and sprockets, clutch, and engine, but less stress than riding the bike does, so it won’t hurt anything at all.
Why do motorcycle batteries die so fast?
All too often, motorcycle batteries die young, murdered by neglect. Dehydration, improper charging, and a slow discharge during storage all shorten a battery’s life. … To prevent these draws from killing your battery, you could disconnect the battery, but even if there is no load on them, batteries self-discharge.
At what voltage is a 12v battery dead?
For a 12 volt, leadacid battery, the voltage measured between these two points should be between 11 and 13 volts. The closer the voltage is to 13 volts, the closer the battery is to being fully charged. The closer the voltage is to 11 volts, the closer the battery is to being “dead”.
Is 11.9 volts enough to start a car?
Measure and Analyze
When the probes touch the terminals while the car is off and the battery is resting, the multimeter display should show a reading of 12.2 to 12.6 volts (full charge). This voltage range means the battery is in good condition for starting the vehicle.
Is 14 volts good for a car battery?
It should read close to 12.6 volts when the car is off. … If the voltmeter reads between 14-15 volts then the battery is normal. But if the battery reads over 15 volts or less than 13 volts, then there might be a problem with the voltage regulator, the wiring or the alternator.
What voltage should a motorcycle battery read when running?
Battery voltage with the engine running at around 4000 RPM should be around 13.8 volts. Could be as low as 13.2 or as high as 14.2 or so.
Is a motorcycle battery 12v?
Most motorcycles use a 11v electrical system with a 12v lead acid battery. These batteries are physically smaller than those found in cars and so are of lower electrical capacity. … Most modern motorcycle batteries are 12 volts. some older motorcycles have 6 volt batteries if there was small dirt bikes.
How long does it take to charge a 12v motorcycle battery?
So, how long does it take to charge a motorcycle battery? At least 6 hours and up to 24 hours. A brand new lead acid, 12 volt battery under a constant-current charge, will take 5 – 8 hours to charge up to 70%. The remaining 30% will require another 7 – 10 hours before it is ready to install on the motorcycle.
