Question about Canon SPEEDLITE 580EX TTL Flash
The capacitor (neck) is no longer hold a charge or charging circuit is going out on a extended breaks.
Save your money and buy ATG's Godox TT685c.
If you buys two, then you got ATG wireless radio ETTL II flashes.
It would cost over $1,000.00+ USD to buy two Canon 600EX II-RT just to do the same with two ATG's.

Turn on flash while pressing some of those buttons with good batteries
Try switching from Meter to Standard Mode and move head around.
Try move the flash head(flash tube) in Manual mode.
It's in electronic locked up because you're moving that flash tube zoom too much. 98% of photographers use that mode:-(

The rating in milliamps is a matter of battery capacity and charging rates. The higher the better as you will get more flashes per charge as long as you have the correct charger to match the batteries’ capacity and use the correct charging times. Aside from this issue of duty cycle between charges- this has no effect on the power of the flash unit as to output. This cant burn out or damage the circuitry.
The issue here is VOLTAGE. Most AA alkaline batteries provide 1.5 volts. Most rechargeable AAs provide 1.2 volts. We are looking at a voltage differential of 1.2 volts (a 20% deficit) if 4 batteries are required. This MAY cause slower recycling times in order to attain a full charge for each shot. In SOME units that can cause a bit if overheating due to strain on the step up circuitry.
It so best to check with the manufacture or distributor of you flash unit before purchasing you rechargeable batteries and charger. If you units have a built in charging circuit this can definitely be problems if there is a mismatch in charging rates and voltage. If this is the case be sire to check your manual or with the manufacturer or distributor- there must be a list of compatible batteries.

These instructions are for the 550ex and I imagine that the bodies of the flash units are the same.
As with any project, make sure to get a good workspace with plenty of light where you won't drop any screws and lose them...
1) There are 4 screws on the bottom of the flash unit that you'll want to unscrew first. Carefully tilt back the bottom section away from the red filter which covers the "eye".
2) There is a set of wires going to a white harness in the piece you just tilted off which you can carefully disconnect with a small flathead screwdriver working it on either side.
3) The same type of harness attaches another set of wires but this one is just inside the body of the flash in the cavity you just opened up. This one is a bit wider and you should undo that harness in the same, careful manner.
4) Next, you have to remove the master/slave switch which is attached with two small screws that you'll need to carefully undo. The actual switch is attached to the tiny board you are unscrewing. There is a plate covering that switch that is the piece you actually push when you want to switch it. That piece will come out when you take the actual switch out so remember which direction it went.
5) Now you should have exposed four small screws as you look straight down into the piece you're working with. These screws hold on the shoe you're replacing. With some decent force against the screws, carefully unscrew them. These don't come out very easily so you want to make sure you have the right sized screwdriver that fits and that you're applying some downward force. MAKE SURE you don't strip the head on these screws.
6) Turn the whole piece so that the shoe is facing upwards. Now you can carefully pull off the shoe. Make sure to not lose the loose spring that is under this thing. You'll see that there are 5 prongs sticking up, a horizontal metal piece, and a small rod looking piece with a spring that fits over it. Take note of how these all go so you can put the new one on with those pieces in the right places.
7) Put the new piece on and screw everything back in the reverse order. Voila! You just saved yourself a bunch of money and hassle. Thanks for the tip on where to get that piece, by the way, I had been looking around for it.

is your master flash set on a camera? The EX II has something that makes it have a 1 second delay when using sync mode, unless the master flash is set on the camera.

You can try to use a super bonding agent with filler such as 'Q-BOND superglue kit' which is normally sold in many auto shops and can also be found on Ebay: it is not an ordinary superglue and is commonly used to repair difficult plastic and metal parts.
Q-bond also has a very long shelf life even after opening the container as it is almost pure superglue!
Hope it helps.
