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

Didn't help me. I admit the possibility that I hooked it up wrong, but I don't think so. Maybe I just misunderstood. Anyway, I had to buy a new car battery in a few days.

, I work full time and drive a 2018 Honda Goldwing. With this charger I can keep my bike always ready by using a 12V 600Ah home battery to keep the bike battery going. The consumption of the amplifier is very low, so I don't even notice it; Just make sure you have a decently sized home battery to support this.

I bought this (and cigarette plug leads) and installed it in my toy tractor to keep the RZR battery charged. My toy truck has solar panels and I was a bit concerned that the charger might draw too much current for the RV's batteries to last all night, but that's not the case. It keeps the RZR battery charged without destroying my RV's batteries.

Worked like clockwork for between 2 and 3 weeks to disconnect the 12 volt starter battery from my boat's 12 volt battery. However, sometime in the third week, this charger died. Went back to my boat and the status lights don't work. Disconnect, reconnect, nothing. The 15 ampere fuse is still intact. Fortunately, this happened during Revane's return.

Great product. Worked great on my Harley in offline storage with no power to the AC charger/server. I have a large marine deep cycle battery connected. It fully charged my Harley battery and then kept it fully functional for over a month before needing to recharge the marine battery. I'm sure the Marine's battery will last longer (hopefully not that long between rides before the end of the year) if the Harley's battery is fully charged from the start. Great solution for me. Exactly what I need.

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

An excellent solution to what seems to be a rather complicated problem. A remotely stored vehicle with no AC power and its PITA to move the battery in and out of the vehicle. Very few products on the market offer reliable metered battery charging. Aside from CTEK, this is the only one I could find. I love CTEK products but it was cheaper so I decided to roll the dice. This works great so far. I use an old Deep Cycle as a source and every few months when I'm in the area where the car is parked I
