Now this is an AC to DC charger that will plug right into your standard 120 volt wall outlet. And that will automatically charge test and maintain your 12 volt battery. This will work with a variety of lead acid battery types including your flooded, AGM, gel, enhanced flooded and deep cycle batteries from three to 400 amp hours.

This does have an amp matic charge that's going to determine your battery size and adjust the charging current to suit your battery. It's got a maximum charging amperage of 10 amps. So it's going to be perfect for charging your car truck, a motorcycle, tractor, RV, boat basically any other 12 volt lead acid battery. This does have a nine step charging algorithm that analyzes your battery condition and then automatically charges and maintains without overcharging. It's got a low voltage detection rating of half a volt.

It does have a built-in battery desulfator to help restore your lost battery capacity. It will automatically test and indicate if there is a battery problem It's very simple to use with the led lights here that indicate your charging status and if there is a problem. It does adjust the voltage based on temperature. So it can work in temperatures as low as negative 40 degrees fahrenheit. And if it does turn off it has an auto memory feature that remembers the last selection so that it can power right back on and jump back into the same settings.

This power supply mode provides consistent power for your vehicle tuning diagnostics and troubleshooting. So really nice option there. Overall, lots of great features to make sure that your batteries are going to be well taken care of. This case is nice and durable. It does have these wall mounts already established.

So you can just put a couple of nails or screws through there. Get this mounted on your wall. The cable here that plugs into your 120 volt wall outlet this is six feet long so it gives you a little bit of adjustability there as to how far away from your outlet you're going to mount this. And then, this cable that reaches out to your battery is also six feet long. It's got the SAE connectors here. And then you've got two different ways of connecting to your battery. So you've got your clamps which are going to provide a nice quick easy way to connect to your positive and negative posts on your battery. This is more of a temporary option. And you just simply connect the SAE connectors there get it connected to your battery. Or you've got these islets here that are more of a permanent installation. So, if you're wanting to just use this for basically one application you can permanently install these on your battery posts and then this will attach to your vehicle. It's got this waterproof seal and cap help keep out any dirty water when you're not connected to power. And then, so you can be out enjoying your SUV, or your tractor or whatever it is that you're using this for. And then when you pull it back into the garage you can simply just flip that cap make that one connection and then it can start charging up again. Rather than having to make that connection and then attach it to your battery. So, just a little bit more convenient for you.

    If the Converter # PD4645V for your Parallax 7300 is converting power from 120 volt to 12 volt but your battery is not taking a charge you will either have a wire damaged/disconnected wire or the battery needs replaced. Depending on the age and condition of your battery it may not be able to take a charge. You will typically have to take your battery out to take it to a auto shop to have it tested.

But if they are the exact same battery, and both are charged equally, then it will be pretty close to the same rate. I have added a link below to our entire selection...
