can I use it between my dual battery in my car for a second battery stay life?

Not sure about that. My guess is that it would depend on how the batteries are wired. I suggest that you ask a certified auto mechanic or a Flaming River rep. What I can tell you is that this is not a three-way switch but simply an "on/off" switch.

I guess you could .Mount it to the fire wall or inner fender well either make up your own cable with eyelets on both ends or you can buy one. I really like the unit its a great buy and easy to install. Good Luck I hope this will help you. NOT LOSE THE KEY I got a little chain and hooked it up to the key and frame and it will be right there when I need it.

Hi, I use this item in my motor home and it works perfectly. I could attach it on a side wall and that is why I bought it. Great product!

This product is mostly used to disconnect/connect power from the battery to the vehicle. If you know enough about circutry, it might work for your second battery. If you do not know about circutry, I would recommend you consult an Automotive Technician before experimenting.

I don't connect it to constant because it could drain your battery. I rely on the back up battery when the car is off.

You can use it taking off one and using the other but not two at the time. This battery comes like two OEM batteries connected to eachother, one is bigger than the other. You take off the OEM battery and put unstead the extended one, and put on the case that comes with it.

Technically you can, but I surely would not leave the device in the car when not in use. The swings in temperature may melt the device and/or damage the battery.

Just one fuse to the second battery (+) to your unit. My second battery is hooked to two hidden cameras. (Vandals in my block) so the battery runs 24/7. it'll charge as you drive your car. Hope this helped. DP in NY

Yes, if you use it with your car turned off. As long as the engine's running your battery won't be drained.

I have not timed it, but I have not had my battery run out on me yet. Unless you have a great price on a second battery, why not give it a try with just the one and see if you in fact do not need the second.

That is a really good question and I'm not sure I can give you an answer for it. I have used my device strictly to jump start my car death battery so I don't really test it real well.Sorry that I can't be of real help, hopefully you'll find someone who can give you a real answer!!!

Only if you're sure the battery is dead!! Lol... No, the amperage from a car battery is way too high. It might be a creative way to void your warranty, that's for sure.

yes it would but I would use a battery isolator so that your alternator charges both batteries but only car battery starts car and this battery is dedicated to audio system ... this way you don't run down car battery while playing system with engine off... also use a voltage controller with adjustable cutout and solenoid switch so you don't drain this battery.. hope this helps :)

Of course it is possible . the front side of the connector to positive and the side part to negative of the battery . BUT why do that ??? it will be ON all the time . you want it to turn ON when the car is ON and turn OFF when the car is OFF .

Yes you can, but in the long run it's not good for the battery. It also has the car charger.

Yes it can, as long as it is the same battery number you are replacing. This is a comparable battery. It should have a longer life between charges as well.

Yes! it is excellent for car batteries and will maintain the charge without overcharging. - Len - 661-245-2000 - Racecrafters-USA

Yes, Thats how I always used it. This battery will die after a couple of years. Might that be your problem?

This has an AGM battery that is 12V inside it, so yes it can be connected to another such battery (and it doesn't matter whether you're using it for "jumpstarting" a car or for adding time to how long a deep cycle battery will last, it does all of the above). Just beware that the battery inside this may not be as powerful as it's made to sound. It's actually rated "22 amp-hour" hinting it can supply 1 amp for 22 hours (at 12V), or 2 amps for 11 hours, or 3 amps for 7 hours, etc. Many deep cycle batteries (that are about the same size as a car battery) can supply 6 amps for 8 hours, so this is about 1/2 the power (and 1/2 the weight).

You can but it ruins the battery. The battery will become dependent on the constant charge and will weaken.
