Although a motorcycle battery and other types of vehicle batteries are built for longevity, over time batteries will slow down and eventually wear out. This occurs when the sulfate that flows over the plates begins to build up a residue on the plates, slowly diminishing the conductivity.
Choosing the correct battery :
In order to choose the right size motorcycle battery, you’ll need to know the cold cranking amps (CCA) of your bike. Technically speaking, CCA is the number of amps a lead-acid battery at 0ºF can deliver for 30 seconds and maintain at least 1.2 volts per cell. And you’ll need to measure the length, width, and height of the cavity to ensure a correct fit.
Installing the new battery :
When installing the new battery, reverse the order and connect the positive cable first before connecting the negative. Take extra caution to identify the positive and negative terminals before attaching the cables. Accidentally reversing the polarity can cause the battery to explode or inflict a great deal of damage to your bike’s electrical system.
Recharging :
Always check the voltage of your motorcycle battery before recharging and never charge your battery at an amperage more than 1/6 the rated capacity of your battery. If you have an 18 amp-hour battery, you can charge it at a maximum of 3 amps. Therefore, most battery tenders offer charging amperage of from 1/2 amp up to 2 amps. NOTE: NEVER USE AN AUTOMOBILE BATTERY CHARGER ON YOUR POWERSPORT SEALED BATTERY. Never recharge a motorcycle battery or any type of vehicle battery with the vent caps open. When you’ve finished charging, turn off the charger before removing the charger cables from the motorcycle battery.
To ensure that your new battery has a long life, it’s imperative to find the right size for your bike and not to overcharge. Using a battery that is too large for your bike or overcharging the battery are the two most common causes reducing a battery’s lifespan.
