Batteries wait for their new owners in a state of hibernation called dry-charged, which means the manufacturer has dried the preformed positive and negative plates, assembled the battery and sealed it in a bag that doesn't contain oxygen. It can sleep like this for two or three years without a problem.

The biggest single harm that can be done to the life expectancy of a new battery usually occurs when it's sold. In the rush to get a new machine set up for sale or to get the customer out the door with his new replacement battery, many batteries are simply filled with electrolyte, installed and pressed into service within minutes of being unwrapped. Sound familiar? It's all wrong. What this procedure buys you is a battery that will never have more than 80% of its powerever! For this reason, many riders prefer to prep their new batteries themselves to make sure it's done correctly.

Here's the actual factory-recommended service procedure, and don't be too surprised if you've never heard it before.

First, unwrap the battery, unkink the vent tube and snip about a half-inch off the end, unless it's a maintenance-free type and doesn't have a vent tube. Next, fill it with electrolyte midway between the high and low level markings on the case. Next, let the battery sit for one or two hoursafter which the battery will still be at only 65% of full charge. Check the electrolyte level and add electrolyte if required. That's rightadd electrolyte. This is the only time in the life of your battery that you can ever add anything but water.

Nowsurpriseyou must still charge the battery. If it is a refillable lead-antimony type, it should be charged at one-third of its rated capacity in amp/hours for four to five hours to get it to full charge. Honda and Yuasa recommend that the maintenance-free type should be charged with a constant-current charger that can drive the charge with as much as 16.9 volts and closely monitored not to exceed full charge Afterwards, recheck the level and add water if required. Finally, let the battery cool so the case contracts enough to fit into its typically tight little holder, run the new breather tube (if it has one) carefully through the original factory routing, being sure that it's well away from your chain and you're ready to go.
