You have mentioned a need for a resistor. What would be the occasion for using the resistor?
Older components may not be compatible with the modern technology. Since the battery was introduced more than 10 years ago and has become a part of the racing scene, many of the component manufacturers have modified their components to be compatible with the 16-volt idea. If a component has a 12volt/16volt designation, there should be no issue with 16 volts.

This cannot be stressed enough. Contact the manufacturer of the product if there is any doubt. Their professional opinion will serve you well and insure that you get the best performance.

Can you use the three-post model instead of the resistor, and the two-post battery for the 12-volt components?
It is recommended that the two-post battery be used with the resistor in applications that do not use an alternator. Using the three-post battery without the "boost box" and a 12-volt alternator can result in a cell imbalance.

If you use the three-post battery and a boost box with a 12-volt alternator, what components will have to be run on 16 volts?
The ignition and starter should be run on 16 volts. These are the primary components that benefit from the system. All other components should be run on 12 volts. With the exception of the starter, not more than 15 amps should be placed on the 16-volt side in the three-post side of a three-post with boost box application.

Will 16 volts hurt my gauges?
While there haven't been any known instances, a concerned racer can use a resistor with the two-post battery, or you can hook the component to the 12-volt post on the three-post battery. Some lights may be brighter, but they will not be detrimentally affected. During testing phases, computers will work fine on the 16 volts. However, you shouldn't have the charger plugged in and charging while trying to download or print. Basically, 20 volts will be going into the system and could affect the printing operation.

Can I charge the battery while servicing the car in the pits?
There are only three circumstances that would prevent you from charging the battery in the pits:

1. If you attempt to charge the battery while printing out from a computer, you will get a haywire graph printout.

2. If you are bumping over the engine when adjusting the valves, this will cause the charger to surge and can blow out the circuit board in the charger. The charger is constantly sensing the voltage and adjusting it during charging. When you bump the engine over, this causes the voltage in the battery to immediately drop, signaling the charger to increase the amperage immediately. This results in damage to the circuit board.

3. If you are warming up the engine, this procedure will also lead to the same type of damage listed under number 2.

Can I leave the charger on overnight?
Yes. All of the chargers are fully automatic. When the battery has reached full charge, the charger will either shut off completely or provide a float charge of less than one amp. Using the 25-amp charger, a fully discharged battery will need a full overnight charge. Chargers should not be left on the battery for more than 24 hours.
