Not at all these batterys are used to give u that power u need for ya amp battery is to small 2 start ya car if thats the case just use your battery you have now but if you are powering amos and subs depending on what you have it may drain your battery i use it because i have 4 12s mids and highs amp and sub amp 2 6x9 and before i bought this battery my voltage was droppin low so to answer your question i wouldt just use this battery i dont think it will even crank your car

The short answer is there's no way this battery would serve in an application for a car jump starter. It's designed to provide a very low current draw over many hours as a power failure backup. Any application for a car jump starter requires a massive current draw over a short time frame (seconds). I make no claim as an expert, but your application doesn't fit this battery.

No it will not run better. You could use a cord that is smaller in size with less resistance. Double theh voltage and you cut the amps in half.

Yes this could work as a secondary battery to power an audio system.. better yet - why don't you pair this with an 1500 Watt 12v-120VAC inverter then you can use a regular 115 VAC amp to really boom it away.

I'm not sure. Mine is running a car stereo. It can run for sereval hours. I just don't know how many amps I'm pulling from the battery.

As long as your radio runs on 12VDC. This battery is rated 12amp hours which means it can supply 12 amps at 12VDC for 1 hour before being drained and needing a charge.

First...yes. You can use this to replace your normal starting batt. Its designed to start the car and allow you to run your accesseries without the engine running. And second, No...You dont have to do that. The battery is just a energy " piggy bank". Its job is to store the energy made buy your alt and send it out when needed to what every your running inside the vehicle. The reason you get a batt like this is because it can discharge many times and not eventually degrade the batterys effectiveness over time. And it helps stabilize vehicle voltage. Its a very good batt.

You can, but the battery would not last long. It is designed to be used while the vehicle is running. I am very pleased with mine, it works great!! A lot of power at a great price!!!

To get all the power from the amp I would run two battery plus the battery you already have soThat would be 3 total battery.. I have 2 of those amp an I am running 5 battery and boy it's banging

Easily! This battery is great for your system and I use it with 2 2400w amps at 1 ohm and it works great. If that's all your running you could use a smaller battery like the 800 and you'll be fine

Yes you can . I use it with a generator to keep the agm battery charged in my race car. Thank you

No, you can't use it because it can handle only small load like 10mA. Car batteries' load is in the range of 5-10A. You will burn this tester in no time.

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.

I would be careful because the power supply that comes with the amp is a regulated system. If you could get some sort of regulation circuit after your batteries it should be okay.

Why would you want this for your car ,it's not very good not a lot of power and cuts out at high volume save your money get a regular car amp

This can provide some power for "jump-starting" any car, but realize that the battery in this is the size of what you'd see on a riding lawn mower or generator. Since it's really not that big, I find the "Gives you 500 amps" labels a pretty big lie. I hooked up another brands unit like this to my car and disconnected the regular battery to try it out. It started the car (ford festiva 4cyl), but the starter was slow barely going. I believe this has a 18 amp hour battery just like mine. If I had a fully drained car battery (like from a light left on all night) and I left it connected while hooking this up, I'm afraid the drained battery would "steal" most of the charge from this battery and probably make both too weak to start the car in as little as 30 seconds. So I'm not keeping my hopes too high on these, especially if talking about a fully drained car battery (whereas if you left lights on while in a movie for 2 hours it has a good chance of starting it). Feel free to look at reviews (both some low and high ones) and see if others suggest about the same thing. Also FYI if you want a way to compare these to your car/truck battery, here's one OEMs definitions of rating batteries: CCA (Cold cranking amps) = The discharge load measured in amps that a new fully charged battery can deliver at 0 degrees F for 30 seconds and maintain a terminal voltage greater than 7.2 VDC. CAA (Crank assist amps) = The discharge load measured in amps that a new fully charged battery can deliver at 70 degrees F for 5 seconds and maintain a terminal voltage greater than 7.2 VDC. These battery packs are labeled using the CAA system, so to convert to CCA dividing the "500 amps" by 6 will give you a closer number (and I get that 6 factor from the 30 sec test of one versus 5 sec, not to mention temp factors).

Yes you can. I have it on a 1500 watt I do recommend anybody with over 800 watt amp have one it saves lots of wear and tear on your car battery. I hope this helps I myself love mine.
