# What voltage should a motorcycle charge at?

Contents

Ideally, a charging system that is efficiently charging should read anywhere from 13.2volts to 13.8volts DC (or above) at idle.

## What voltage should I charge my motorcycle battery at?

Charging voltage

State of charging of battery Per lead-acid battery cell (2.1v nominal) 12v nominal batteries (6x cell)
Minimum for charging 2.15v 12.90v
Trickle charging 2.25 – 2.27v 13.50 – 13.62v
Normal charging 2.30 – 2.35v 13.80 – 14.10v
Fast charging (risk of gassing) 2.40 – 2.45v 14.40 – 14.70v

## Are motorcycles 12v or 6v?

Most modern motorcycle batteries are 12 volts. some older motorcycles have 6 volt batteries if there was small dirt bikes.

## What should a 12v motorcycle battery read when fully charged?

A fully-charged 12-volt battery, allowed to “rest” for a few hours (or days) with no load being drawn from it (or charge going to it), will balance out its charge and measure about 12.6 volts between terminals. When a battery reads only 12 volts under the above conditions, it’s almost fully depleted.

## Will riding my motorcycle charge the battery?

Do motorcycles charge their batteries while riding like, say, a car do? Yes, motorcycles charge the battery while the engine is running in the same manner in which a car charges its battery.

## 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.

## What are the signs of a bad stator?

The most obvious symptoms of a bad motorcycle stator include no spark, weak spark, or intermittent spark (also known as misfiring). Hard starts and a poorly running engine can also be clues that your stator needs to be rebuilt or replaced.

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.

## What are the symptoms of a bad voltage regulator on a motorcycle?

After all, the voltage regulator is supposed to keep the power flowing to the lights, so it’s no surprise that those lights don’t work right anymore once this part goes bad. This issue can extend to your headlights, dashboard lights and even your sound system.

## Can I use a 12v battery on a 6v motorcycle?

At idle it probably makes close to six volts. … If you change the regulator to a 12 volt DC unit with the 12 volt battery it should work. You will not get any charging at idle, but once the bike is at 2000 or 2500 rpm it should be charging.

## What voltage and amp should I charge my motorcycle battery?

ALWAYS use a Motorcycle/Trickle Charger when charging Motorcycle Batteries. A Motorcycle charger supplies NO MORE than 7.5 Amps during the charging process. Make sure your charger is the same voltage (6 Volt or 12 Volt) as the battery you are charging. Charge for a full 8-12 hours.

## Can you use any 12v battery on a motorcycle?

As long as your using a 12v battery on a 12v system it will work. That is all. ’75 Suzuki RE5, ’78 Honda GL1000, ’79 Kaw KZ1300, ’82 Honda CBX, … The bike is only going to draw as much current from the battery as it requires.

## How do I test a 12 volt battery with a multimeter?

To test the charging system, hold the voltmeter leads on the battery terminals while you rev the engine to about 3,000 rpm. The voltage should rise to a value between 13.8 and 14.5 volts, which is the minimum voltage needed to charge a typical 12V battery.

## How many amps does a 12 volt motorcycle battery have?
