What kind of battery charger do I need for a motorcycle?
A: When you’re considering the best size battery charger for a motorcycle battery, the answer has to do with the cell. The voltage always needs to match, so 12-volt batteries require a 12-volt charger.
How many amps does a 12 volt 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.
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.
What amp should I charge my motorcycle battery at?
When charging a motorcycle or other small battery, the battery charger should not exceed 3 amps. Most automotive types of battery chargers are not suitable due to higher current output. While maintaining a battery at its full state-of charge will ensure optimum life, overcharging may significantly reduce it.
Can you leave a trickle charger on all the time?
Trickle chargers are low-amp chargers that top up a drained battery to keep it at its maximum capacity. … It can be left on indefinitely, charging a car if you only use it once in a few months, and it will ensure that the battery never goes flat.
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.

How long does it take a battery tender to charge a motorcycle battery?
To be safe, assume that the batteries require a full 100% charge after the cells are filled. For example, a 16 Ah battery will take about 13 hours to get to the absorption voltage (constant 14.4 Volts). It may take another 6 to 8 hours to reach the float voltage (constant 13.2 Volts).
How many amps do I need to charge a 12 volt battery?
Most battery manufacturers recommend sizing the charger at about 25% of the battery capacity (ah = amp hour capacity). Thus, a 100 ah 12 volt battery would take about a 25 amp 12 volt charger (or less).
How many volts should motorcycle battery have?
A fully charged battery should read approximately 12.6VDC. If it reads at or below 12VDC, recharge the battery. Allow battery to rest and test again. A battery that has been fully charged, rested, and tests between 12 and 12.6VDC might start the motorcycle, but it’s not holding a full charge.
