Review on ⚡️ Tecmate Optimate DC-DC TM-500: 12V/12.8V 2A Sealed Battery Saving Charger & Maintainer by Michael Cooper

I am using four 100 watt solar panels to charge a 12 volt deep cycle marine battery. This battery is used to charge other batteries (AAA-AA-CD and 9 volt cells as well as cell phone batteries and other USB batteries) with 12 volt input chargers. But I also power various motion sensors around the house from a 12V sealed lead-acid battery and I needed a way to charge them. This little charger does the job perfectly. I can charge 12v small sealed batteries (one used and others as spares) overnight without using the inverter to run a separate 12v small sealed lead acid battery charger. Thanks to the makers of this little charger!
