630 EOS draining battery with unit off

Mostly a battery discharges because something is switched on rather than a short circuit, although it is possible damaged wiring could bridge two circuits.

If the radio has been replaced recently - some radios aren't suitable for some vehicles and a discharged battery over a period of a few days will be the result.

It would have been helpful if you had told us the size of the battery (amp/hour) and how long a fully charged battery takes to discharge?
This would allow us to determine the approximate size of the discharge, though this can and should be determined by connecting an ammeter in series with a battery lead - if a thorough visual inspection reveals nothing, the discharge will clearly be seen on the meter so the fuses can be drawn in turn until the discharge disappears and so the guilty circuit will have been discovered. The next stage will be to investigate everything on that circuit...

It is unwise to delve very far when troubleshooting electrics on a modern computerised vehicle without reference to a wiring diagram.

I don't know about cars

After checking that there is nothing left on which could do this (you would notice) the likely causes are

- battery self discharging due to end-of-life
- fault in the alternator unit permitting discharge to earth

An auto electrician can see which very quickly

Try disabling everything you can through the software, if not possible, unplug them. Then plug one in at a time and leave it overnight. If its OK in the morning, plug in the next item, and so on. Make sure battery is fully charged between each test. When the unit discharges overnight again, the last item you reconnected befroe it discharged is the one causing the voltage drain.

1. the car drain's the battery even when it is not started or the key isn't in ignicion, the car has a electrical problem, you left a light, the starter could drain it, the alternator as well, or a bad radio is draining the battery even with no key in the ignicion,
2 it's a bad battery (discharges it self by beeing counicated inside).

solucion 1. to see if the car is drainin the battery would be by disconecting a battery termina and see if discharges again, if not, then the car drain's the battery.

solucion 2. if the battery discharges even when if it's disconected from the car, then change the battery.

warning, the first cause coul'd induce to a self discharging battery. even if you changed the battery, do a litle monitoring to be sure it's not the car that is turning the battery bad. how? if you install a new battery, leave the car for a few days (i mean do not start the car) and see if the battery discharges, if so, then you have to search what is draining the battery (that could be a very costly work, time and money and complicated). or put a ''battery disconector'' so the car cannot discharge the battery.

Either the battery, the battery cables/connections, the alternator or alternator cables/connections (in the extreme a drain could cause battery discharge). Have battery tested. Look for signs of corrosion around cables. If vehicle won't start after sitting but will restart when turned off, suspect battery. If won't restart after driving, suspect alternator.

This is a quick repair for under $60 at most independent repair shops.

Well.. the EOS 630 is a really old camera.. they don't last forever.

First thing I would recommend... test the new battery with a volt meter or battery tester, just to make sure it didn't die on the shelf. Or try another one, just to be sure.

Next, check the battery contacts, preferably under a magnifier. You could have corrosion, or a bent contact, that might be preventing contact with the battery.

Assuming none of those work, you have a more complex problem. It certainly might be fixable, but you'd want a good repair tech to take a look at it. However, that's probably a bad idea.. they charge by the hour for actual repairs. You can find a working EOS 630 on eBay these days for under $30, sometimes with accessories. I wouldn't spend much money trying to fix this, but a few checks around the battery area are a good idea.

Get it serviced to find out if it is repairable or only insert battery to use then remove when not in use
