Since I have been having some trouble with my 94CDE starting after sitting for several days, I have been doing some research on types of batteries and I ran across an interesting article on voltage regulation. Basically the article stated that there are three types of batteris in usage now and they all require different voltages to properly keeep them charged. Apparantly older batteries used antimony to harden the lead and lead/antimony batteries do not require as much voltage to charge them as the newer types. The first of the newer type used calcium to harden the lead and this allowed for a "maintenence free" battery. The second of the newer types was a hybrid of antimony/lead on one pole of the battery and calcium/lead on the other. According to this article, the newer types need to be charged some where between 14.2 volts and 14.5 volts while the earlier antimony/lead batteries can be charged in the high 13s or so. The article went on to say that most battery failure is due to improper voltage when charging.

This brings me to my question. My voltage regulator is not reading even in the high 13s when driven on the highway at high speeds. Is it time to change it? I'm thinking about getting a solid state voltage regulator rather than a mechanical(Bosch) one for two reasons: cheaper and reportedly the electronic units do a better job of regulating the voltage. Any input would be appreciated.
