I have an old (~10 yrs?) SCS750 controller that is not holding settings in memory. Last summer Raven suggested changing the internal battery. I'm just now looking into that; today Raven is searching for their part number. This is the old 3 circuit board unit with a 24pDIP lithium A0957B battery; the battery is LT brand. It also has the number M48Z02-150PC1 printed on it. This number returns a number of hits on google; here is one link with specs. Do any of you have a good reliable source for such a battery, if Raven cannot furnish it? TIA Gary |
