Can I use the new "photo" batteries in my Momentum Option Adapter and get a longer service life?

No, Modicon does not recommend using "photo-type" batteries in place of the regular alkaline batteries. Photo type batteries are designed to have a level discharge cycle life that drops off steeply at the end of the battery life. This will impact the low battery warning LED and you will not have the 30 day window to change the battery. The JNN and PNN adapters have circuitry designed on the discharge cycle of the alkaline battery.
