Batteries that sit unused for long periods of time (3-4 weeks+) can end up with sulfation built up on the battery plates. Once this happens, they'll begin to experience a downturn in performance and run time. They can also become difficult and even impossible to charge. However, this can all be prevented from happening.

Did you Know... 

Less than half of the motorcycle/ATV owners maintain their battery over the winter. Lead acid batteries lose 1% of their power a day!

If your machine sits from December - March, you now have a junk battery. When the machine sits, the battery sulfates; this condition is almost impossible to reverse.

People try to charge the bad battery and then hope the vehicle's charging system will fix the problem. WRONG. You just over tax the charging system, burning out the stator, rectifier-regulator, connections and wires. Good charging systems keep good batteries charged. They dont re-charge a dead battery.  Once the battery is dead, it is not going to recharge.

Dead Battery Solution's

1. Keep a trickle charge on your battery when the machine is not in use. If you suspect a bad battery, make sure you bring your motorcycle or ATV to your local service center. They can do a load test for you. If your battery fails the test, replace it. It costs a lot less for a new battery than to replace your whole charging system. 

2. Know your battery. There are different types of batteries, and therefore, different ways to maintain each one. For example, a conventional battery will need to have the proper amount of fluids and added and maintained. For a maintenance-free battery, you will need to keep the terminals cleaned and possibly even spray some sort of protecting spray on them and the connecting hardware. 

3. Do not let your battery freeze! This will be the quickest and easiest way to destroy your battery. 

What Causes a Battery to Die? 
 

1. Climate: Colder climates tend to be hard on batteries from a starting standpoint, and for the fact that many people put their bikes away for the season when not using. Sometimes without charging properly.

Hotter climates tend to discharge batteries quicker, and dry out batteries quicker. "Average" climates are the best for long battery life.

2. Usage: A battery that is used every day has the most chance of living a long life. Batteries that sit a lot, many times are neglected. This shortens overall life. Periodic charging is the best defense.

3. Sulfation: Sulfation is a buildup of crystals on the plates of a battery. This comes from not charging a battery properly. The more sulfation that builds up, the harder the battery is to charge, until finally it does not charge at all.

4. Complete Drain: Have you ever left your key on, and totally killed the battery? If recovered in a short time period, the battery should charge back to 100%. But every time this happens, it is similar to the battery having a "heart attack", and shortening its overall life. Always turn your vehicle off with the keyed ignition switch, not the "kill switch".
