Hello, everybody. This is Jeff at etrailer.com. Today, we're gonna take a look at this OptiMate 7 Ampmatic nine-step, AC to DC, 12 volt smart battery charger and maintainer. Now, this is a nice, compact smart charger which will draw power from an AC wall outlet to automatically charge, test, and maintain batteries on your cars, trucks, RVs, motorcycles, and even boats. This is designed to work with 12 volt standard AGM, gel, EFP and deep cycle lead-acid batteries. Does offer multiple battery profiles that'll let you charge a variety of lead-acid battery types at different voltages.
And it uses a nine-step charging algorithm, which will automatically charge and maintain without overcharging. Basically, they'll analyze the battery condition to provide a customized charge for that battery. It does use a built-in battery desulfator, which will restore lost battery capacity, and it saves sulfated batteries as low as .5 volts. It does test automatically and indicate if there's a battery problem, and it'll adjust the voltage based on the temperature. It does have a pulsing absorption mode, which brings all battery cells to equal strength to optimize performance.
And the ampmatic charge will determine your battery size and adjust the charging current to suit that battery. Now, this does connect to your battery by including two different cables. First one is your standard battery clamps to provide a nice, quick, easy way to connect to your battery. Has your stand, standard positive negative clamp, clamps to your battery. And on this end, the SAE connector that'll plug to the SAE connector on the charger.
Total length on the cable for the battery clamp is about 20 inches. And the other way is a little more permanent, it's the eyelets. These eyelets will connect that'll let you make a secure connection to your battery terminals. Does include this 15 amp inline fuse that protects electronics from potential short circuits. And on the end is the same way, the SAE connector that will connect to the charger with using that.
But what's nice about this one, since it's a little more permanent, they do use a weatherproof seal around the connector, and provide a cap that when you're not using it, keeps out any dirt and water. Same way, the length on this eyelet cable is about 20 inches also. Now, it is a very simple operation. It uses LED lights that'll indicate the charging status. You can see this is all in a nice, durable weatherproof case. Includes the wall mounts, two at the bottom, two at the top to install it. Comes with a six foot long AC supply lead and a six foot long charge lead that has that SAE connector on it. Does also come with a nice instruction manual that'll describe how this all operates. But what's nice is also on the charger itself, they have a QR code that you can scan with your portable device and that'll bring up the instructions. So, if by chance, you don't have the booklet with you, you can just scan that QR code and still get all the instructions you need. Few specs on this, the application is for 12 volt batteries from three to 400 amp hours. Again, the battery types is the standard AGM, gel, EFP and deep cycle. And the maximum charging amperage on this is 10 amps. But that should do it for the review on the OptiMate 7 Ampmatic nine-step, AC to DC, 12 volt smart battery charger and maintainer..
I love that it charges 6V in addition to 12V batteries, both at three different voltage levels depending on the type of battery. It is definitely better-built than a modern Schumacher that you can buy in auto stores. It is made in China, but designed in Japan. It begins every charge cycle with a desulfating cycle. It supposedly also measures ambient temperature and factors that into the charge. It does not apply power to the two prongs when you plug it into the wall, which means you can accidentally let the two leads touch and nothing happens (this is a very good thing). The thing stays on 24/7/365 until it achieves success. I left it on a low, probably dead, 6V battery for 3 days and it was still pumping 10a into it in vain. OptiMate is the best; I use their chargers for wintering my motorcycles too. One negative: when you take it out of the box, the instructions seem very daunting. They clearly designed this to be sold worldwide. It's easy to operate once you use it a couple times.
