TecMate OptiMate DC to DC TM500, 6-stage encapsulated battery-saving 12V/12.8V 2A DC/DC charger and maintenance device

Q: will this charger allow the battery being charged to back feed to the charging battery? I want to use it to charge a battery mounted on a trailer .

Hello, The TM500 will use the source battery to charge a secondary battery; it will not back feed current into the main (source battery). An example that people use is to use the trailer’s starter battery to charge a powersport battery while driving the trailer. Hope this helps.

Q: Will this charger attain a higher output voltage than it's power source?

It depends what the user means upon this question. Here I explain by two viewpoints. From energy converting point of view, of course that input power energy is bigger than output energy. The energy is calculated as voltage times current. From voltage point of view, input voltage can be less than output voltage, so input voltage of source battery or power source can be less than under-charged battery. For example, input battery voltage can be 13V while output battery voltage can be 13.6V. But input current must be bigger than output current. So, energy of input as voltage times current is larger than that of output voltage times current.

Q: See that it is stated for use with lower AH batteries. I’m looking to charge 110ah batteries with no more than 20% discharge. May this work?

It would be like a maintenance charge. It’s max about 2 amps so about 10 hours to get 20ah
