Motorcycle Battery Reading & Maintenance
In this guide, I will share information about motorcycle battery reading and maintenance.

Battery Maintenance
Storing Your Battery
If you’re not using your bike regularly, I would suggest that you remove the battery cables to eliminate drain from electrical components and you should also consider charge the battery every two weeks or so.
For longer battery life, remove the battery from your bike and charge it to 100% or full. It is adviseable to charge your battery every month if you’re storing your bike at temperatures below 60° . If stored in a warm area (above 60° F), charge every two weeks.
Important: Before performing any inspection on your battery, make sure that there are no open flames or possibility of sparks around the battery and absolutely no smoking. Always wear eye protection, protective gloves and clothing.
Cleaning of the battery terminal
Clean the battery terminal when it is dusty or rusted.
1. Set the ignition switch“ OFF” position.
2. Disassemble the front seat, disassemble the ( +) positive battery wire after the ( -) negative battery wire. Remove the battery.
3. Clean the terminal. If there is white dust, clean it with warm water.
4. Assemble the battery wires and grease the terminal lightly.
When your battery is clean, it’s time to check the state of charge. When using a voltmeter, the battery terminal voltage should read at least 12.0 volts. If your voltage is below this or you’ve adjusted the electrolyte levels, a boost charge is required.
Battery Reading Guidelines
The reading guideline below may not be entirely accurate but it will give you some rough idea on how the battery measurement should read.
Ignition ON With Engine Off
12.0 – 12.9V: Normal (Healthy)
11.7 – 11.9V: Weak Battery. You should charge/replace it.
11.6V & Below: Bad battery. Change it especially if you’re using electric starter
Engine ON & Rev above 2000 RPM
14.6 & Above: Bad rectifier/regulator.
13.0 – 14.5V: Normal (Healthy)
13.0V & Below: Minor electrical circuit issues such as, incorrect wattage of light bulbs, alternator (Magnetic coil, fuel coil) or charging circuit fault etc
Conclusion
Proper maintenance and regular checking on your battery will ensure that your bike is in good condition. I am sure you don’t want to stuck somewhere due to the problems with the battery.
Do you have Voltmeter installed on your bike to monitor your battery’s health?
Hi Hazim, both Naza blade Naked 250 and GT250R are the same bike including the Coil. The only difference is one is fairings and one is without. However, only year 2010 and above models are with EFI. 2009 and below are carburetor type.
What the minimum battery leakage on this bike?1-2mA is normal?
Hi Khor, I am not sure the minimum leakeage for Hyosung but in General, 1-2mA is normal. You can also check your battery voltage as the instructions here https://goo.gl/tGr2DT and use my site information as guidelines.
my hyosung is indicate 02.110mA current leakage when in key off position,after i check the leakage problem is come from the digital meter wth taco meter!! when i disconnect the socket of DM,the current leakage is drop to 0.0003mA,for my acknowledge most bike current leakage is not more then 0.1mA,so is that my bike will drain of the battery when overnight?
hello Rider Chris i want to ask is there any difference between coil magnetic for naza blade 250 efi and gt 250 or can work on both ?
Hi Hazim, both Naza blade Naked 250 and GT250R are the same bike including the Coil. The only difference is one is fairings and one is without. However, only year 2010 and above models are with EFI. 2009 and below are carburetor type.
I just charged my battery coz it was unable to start( I’ve parked it for a while without using it). But after the battery is fixed and I started riding, the bike makes battery on sound ( the sound which comes when you turned on the ignition ). Is this normal?
Hi Rohan,
Can you please try to unplug-plug it back in your battery with your bike ignition switched off and see if that helps? Also, ensure your bike battery is a proper one, i.e. recommended by Hyosung or your local distributor. Cheers
Thanks for your swift reply. I’ll get to it n be back!
There are a error.
5000 rpm to 10500rpm the max voltage is 15.0v, 15.4v is dangerous and can damage electrical components
Hi Andre, Thanks for highlighting it. I’ve just corrected it. Cheers
