    Currently running a 2nd battery and amp into a truckbox this project is becoming a pain in the ass as I am doing it by myself so there is some trial and error. I want to see what you "pros" are running as battery(s). I am thinking of AGM battery and putting that in a Marine grade battery box and mounting the whole thing in the truckbox. I am using a Battery Doctor 150 isolator. what all do you run?

    At one time a yellow top Optima battery was darn near the best. It looked like a giant 6 pack, dry cell technology, and it would maintain a steady voltage when lots of electronics were being used. Not sure how big of an amp your talking about or what your trying to do. For the average pickup truck with a 150 amp alternator, two yellow tops will let you run a healthy amp.

    Thanks 9C1Driver. Yes I was thinking Optima, but I am hearing bad reviews of the newer ones, some not even lasting 36months. Any other ideas?

    Group 31 lead acid 1000cca batteries. No isolator and 00 welding cable. An isolator is a nice thought but voltage drop is what you're trying to avoid.

    I don't recommend a deep cycle because a starting battery will provide more peak current. If you were going to sit somewhere with the engine off and talk on the radio deep cycles and an isolator might be the way to go.

    It really depends on what your goals are. You will be better off in the long run if you install an adequate alternator and heavy duty cables. That way you won't need extra batteries.

    you could always run a big assed capacitor between the battery and your amp like the car audio guys do .. I am using a 2.0 farad cap rated @ 12-16 volts in front of my texas star and it seems to work well ... also will filter some noise out ..good luck .. xxx

    The Optima batteries at one time were long lasting batteries. When they moved production to Mexico the quality tanked.

    Look at East Penn Manufacturing, or Northstar batteries. They make some HD ones that have plenty of amperage. But why go that route?? Get an upgraded alternator and one good battery for the back and be done. Something like this.

    You were absolutely right . I upgraded the alternator and the charging cables to 1/0 from the alternator to the battery and to the amp. Make sure you run the same size ground cable from the back of the alternator to the negative of the battery. Now all I have is one group size 29 upfront

    Good deal. It's much cheaper to do it that way in the long run.

    Actually bat caps don't do much for us in the cb/export radio and amplifier application. They work great with car stereo amps because the pauses between drum beats let the bat cap re-charge. In our application as soon as you key the mic on say AM the amp drains the bat cap right away. It won't recover until you stop talking and un-key. There are several old threads about this here somewhere.

    I don't do a.m. just ssb so for me the caps work really well.. my voltage stays very stable during s conversation .. i am also feeding the amp via the cap with a dual battery setup in my diesel pickup using a heavy full 8 gauge wire not exceeding 10 feet also plagerized from the car stereo boys .. I do agree with your thoughts about a.m. being a constant drain in the power circuit..xxx

    A cap very close to the amp can help in installations where you have a big enough alternator but no extra batteries, it smooths out that initial drop while the alternator reacts to the increased load. Caps can be useful, they just aren't a replacement for batteries.

    Lead acid batterys just hold up better. Been through that spiral cell phase once, it ain't for high current. But 600-1000 amps is kinda nuts.
    I used to run 8 volt scubber battery in series / parallel from Lee's battery.
    I plan on doing the exact same thing for my driver on my new 'burb.
