Missing Link Audios Voltage Control Module - The Juice...Is Loose!

If you have ever owned a truck or know someone who has, dead batteries have been a part of your life. Without a battery, your truck is not moving and can leave you stuck in places you would rather not be. Batteries have a tendency to die on you when you least expect it and a majority of times without warning.
There are several causes of dead car batteries. The most common is the buildup of sulfate on the plates. This prevents the proper charging and discharging of the battery. A battery's condition deteriorates worse in the following conditions: temperatures over 70 degrees, storing without a battery tender, and discharging the battery below 10.5 volts. One of the most common issues is under charging the battery. This will significantly add to its untimely demise.
Since the mid '80s, automotive manufacturers developed internally regulated alternators designed around the normal intended use of the vehicle. Little or no allowance was made for aftermarket products like audio equipment, or air compressors. To add to this, several manufactures began using a parameter called RVC, or Reduced Voltage Control. This parameter reduces the charging voltage when the battery reaches 80 percent charge, resulting in a battery that may never become fully charged. Even upgrading the battery or going to a higher output alternator wouldn't have an effect on how the computer turns on and turns off the charging system. What if there was something that could be done to change this? Fortunately for us, Missing Link Audio has already come up with a solution.

The MLA voltage control module works in conjunction with your existing voltage regulator. By reshaping the charging curve, it can improve battery life and condition. A fully charged battery lasts much longer. The depth of discharge directly affects battery life. By keeping a battery fully charged, you can play the stereo system and run your compressors longer. Another key feature of the module is temperature compensation. Newer internally regulated alternators judge battery temperature based on alternator temperature. Batteries located outside of the engine compartment can be as much as 100 degrees cooler than the alternator and cold batteries require a higher charging voltage. The temperature sensor inside the MLA module is closer to the battery's internal temperature resulting in a more effective charge for the battery and improving the performance of high current accessories. High current items like, audio amplifiers, or compressors will overheat and fail if the battery voltage drops too low during operation. By maintaining a higher charge voltage, these expensive accessories are better protected. The operation of the module works in conjunction with and does not bypass any of the OEM fail-safe operations. The PCM or internal regulator can still shut down the alternator if it is overheating and all of the OEM warning lights continue to operate as originally intended.
