FAQ:

Q: Can a 12V battery be converted to 14V?

A: Most relays or electronic devices built for “12V use” are actually designed to handle 14V since, as you found out, all “12V” auto/MC systems actually regulate to 14V since that is what the basic 12.6V lead-acid battery is charged to in a car or motorcycle.

Q: What is the voltage of a 12 volt relay?

A: Automotive relays are called “12 volt” relays, but they routinely are subjected to voltages as high as ≈14.5V when the engine is running and the battery is being charged. I suspect that the OP’s relays are “12 volt” relays in the same sense.

Q: How many diodes do I need to reduce the output voltage?

A: If you wanted to be EXTREMELY el-cheapo, you can add 3 silicon diodes to the output to drop it by approximately 2.1V This however will vary with the current being drawn and isn’t recommended. If you don’t care about proper regulation, then this is okay, otherwise do it properly…. What is a joule per second?
