Maximus,

Quick question about the company, Are you having to send back the bad batteries?

I have a sneaky suspicion that they have a bad batch of batteries.
You have 6 cells in the battery and each cell produces 2.3 volts. Each cell should have a divider in it, to prevent shorting from one cell to the next. Either the plates are shorting out on each other, or internal hook up from each cell is causing the internal short.

With the key off disconnect the ground post on the battery and lightly touch the cable terminal back to the battery as if you’re trying to strike a match. Look for small sparks to see if something is drawing off the battery.

That would tell if there is a draw on the battery but shouldn't kill/short the battery.

Any draw will kill a battery if given enough time.

Depending on the size of the battery even a memory wire to a radio or a relay to an amp that wasn’t wired up right will suck them dead, eventually.

Gave my brother a little v twin to play with since it just sat here. Right off the bat he said something was killing the new battery without even turning the key.

Just food for thought.

I agree that a draw will "Drain" the battery given time but his battery is shorted and will not recharge. 1 of them died while on a trip with a good charging system. Something is shorting the battery not just draining the battery. With the info given my guess is that they are just from a bad batch of batteries, although when I got my next new one I would disconnect the amp and other new equipment just installed to see if something there is shorting them out. If it is OK for a while hook the equipment back up to see if it shorts out again. If it does you found your problem.

+1 with Davej /\/\/\. My brother inlaw ran into the same problem with the stereo on his side by side. The memory and clock had a low draw that drained the battery.

My vote is against the odds of two "new" shorted batteries. I didn't hear him report any testing of individual charging components other than a voltage test at idle. He installed components and then began having problems.

A drained battery will still have residual voltage, just no amperage. A drained battery will take a charge.
A battery with "0" volts is a shorted battery. With tons of parts being made in China, well...
The OP stated both batteries, "0" volts and both would not take a charge, parts store tested and both bad.
Both batteries from the same store, I still say bad batch of batteries.
Battery technology is getting better, but..
Samsung, Apple, Boeing all have had issues with batteries. Different types of batteries but still...

Can a radio memory wire drain a battery, yes,but that would take a long time. Having an amp wired in wrong, you bet! So can other things. With all of the stuff we put on our machines.

no they said to just dispose of batteries properly. I have them sitting in garage right now

I will try disconnecting everything. and see how that does. Not my 1st amp and speakers to install on a bike but who knows maybe I did mess something up. well battery should be here Thursday so ill update sometime then to let yall know... thanks for all advice

You stated that the battery died on a road trip. The first thing that I check for with battery issue is the battery itself. I charge it and check it. (I use a snap on battery tester. You might have to take it to have it tested). With a good battery the next test is the cables. Pull the plug wires off and throw two old spark plugs or ground wires to them, (to prevent damage to the coils) after disabling the ignition. You sand a clean spot on the negative post on the battery and a clean spot on the engine so that you can get a good reading, (very important). Put your positive lead from your voltmeter on the battery cable you cleaned and on the spot on the engine that you cleaned. Have an assistant hit the starter button for 3 seconds. Because both leads are on ground you should get 0 volts. A one volt drop is a hundred amp loss in the cable. You have just performed a voltage drop test. Test from positive to starter and from battery positive to the hot wire on the regulator. Check from regulator to alternator. Voltage drop testing is the best way to check wiring on any components. With positive cable connected you can hook up a test light between the negative cable and the negative post. There should be no transfer of energy if the ignition switch is off as you have no clock or alarm. Also most meters between the negative post and the negative cable in amp draw mode. A two amp draw will kill a 700 amp car battery in 28 hours. I hope that this helps.
