The alternator creates alternating currents to run the bike and charge the battery. The regulator/rectifier changes, or rectifies, the alternating current produced by the alternator into direct current so it can be stored in the battery and regulates the amount of current produced to prevent overcharging.
Does motorcycle battery charge while riding?
Does a bike battery charge while riding? Yes. That’s what is designed to happen, so if your alternator and battery are in fine fettle, a 30 minute ride should easily be enough to top up the battery.
Do motorcycles have alternators?
Do Motorcycles Have Alternators? The simple answer to this question is yes—however very few automotive style external all-in-one alternators exist on motorcycles. Rather, a stator and rectifier/regulator handles the power generation task.
How do I know if my motorcycle battery is charging?
Test 1: Battery voltage a with motorcycle off and then on
Test the voltage of the battery using your multimeter. If your voltage is at or above 12.4V — you’re good. If your voltage is below 12.4V after a charge — you need a new battery.
Can a completely 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. … Once you get the bike running, make sure to ride it for a good while in order to get it fully charged again.
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.
Do I need a trickle charger for my motorcycle?
So yeah it’s best to keep tabs on your battery and keep it charged. The most common battery chargers you’ll come across are trickle chargers and smart chargers. … While both are typically 12 volt batteries, a motorcycle battery has less Amperage and requires less amp charge rate.
Can a motorcycle run without a rectifier?
Without the rectifier and voltage regulator converting the variable voltage AC output of the alternator to a usable 12–14 Volts DC, the battery will not be re-charged or be able to keep up with the demand of the ignition system and any lights or accessories that are switched on.
Can a motorcycle run without battery?
On an electric start only bike, the battery is needed to start the engine. After that, it is the alternator that takes over and provides the power. … Some motorcycles will also be able to run, but have no lights at all as a battery (whether dead or not) is needed to complete the circuit for the electrical system.
Will a motorcycle start with a bad Rectifier?
The rectifier is part of the charging system. If you put a freshly charged battery in your motorcycle, and you have a bad rectifier, it won’t stop your motorcycle from starting, but your battery wouldn’t stay charged. The regulator/rectifier on your motorcycle performs two functions.
How long does it take to charge a 12 volt 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.
How do I check for a battery drain on my motorcycle?
The way to check is to remove the negative battery cable and place your volt-ohm meter in the current (amps) mode. With the key off, place the meters leads between the negative cable and the battery’s negative terminal. The current draw should be zero, but a small drain on the order of a few milliamps is acceptable.
How long do motorcycle batteries last?
Battery manufacturers agree that on average, a motorcycle battery should last 48 months, yet most of us are lucky to get half of that, and in most cases the battery’s premature death can be chalked up to a lack of maintenance.
How do I bring my motorcycle battery back to life?
Turn the charger on low the battery to charge overnight or until the charger indicator says charging is complete. Then turn the charger off, remove the Leeds, and replace the cell caps. Reinstall the battery in the motorcycle, making sure the connectors are secure. The battery should now operate normally.
How often should a motorcycle battery be replaced?
Effective motorcycle maintenance includes performing regular upkeep and replacing certain part when needed. That includes your bike’s power plant: the battery. Conventional batteries typically last two to five years, according to Yuasa Batteries.
How do you rejuvenate a motorcycle battery?
For a small motorcycle battery I made excess – 16oz of distilled water with 7oz of Epsom salts (15oz for a quart if you’re doing a large battery). Fill the cells to the low level line with the nice hot liquid and seal them up. Give the battery a good shaking to mix the liquids.
