Monitoring a battery’s acceptance of a charge can be done in two ways: . With a D.C. voltage meter: This involves a expensive meter and a great deal of time. Charge the battery for a set amount of time: anywhere from to hours, let the battery rest for one hour check the electrical state of charge. repeat the cycle until there is no increase in D.C. voltage. This is the Maximum amount of energy the batter will accept. . Get a battery hygrometer. Get a cheap plastic one with the movable pointer. This should be about $ and will involve exposure to harmful battery acid. Get a sheet of paper and in a location that will not matter if surfaces are damaged hook your battery up for a charge. Write the specific gravity number down on three different cells every hour. When there is no increasing specific gravity numbers for one hour that is the maximum energy that your battery will accept….stop charging it. If you have a battery charger that should shut off monitoring this and it didn’t shut off …it is defective and needs a new monitoring board or has a loose connection. The charger monitoring board checks the charging voltage something like times a second and will notice a full charge if functioning before you will. To charge in addition above this will expose your battery to damage and reduced cycle life. A new battery in perfect shape will charge to .-. V/ cell or .-. specific gravity. These values will decrease in temperatures above F as the battery will accept less energy above that temperature. While you have exposed yourself to battery acid check all the cells they should be reasonably close to the same specific weight.
Motorcycle batteries are dry charged to about %.
If you don’t give the battery a top up charge (- hours)
the battery will only ever be % efficient…
which will greatly shorten the life span of the battery.
The website listed below has a lot of very informational tips etc. in referance to motorcycle batteries.

Get a battery tender then you will not have to worry about it. The one that I bought was less than $.
How many amps is the charger?
new or dead battery over nite
