After buying a new battery (car) after a couple of days went to start and battery was dead flat, after having it charged it was flat after a couple days found the problem was shorted diodes in alternator (was draining 5 amps Replacing new alt. I decided to put a 60-100 amp relay between alternator and battery switching on when car ignition is turned on, the circuit is broken when ignition is off, thus if the diodes short won't drain battery.

Would that be the same fuse for a 2016 Ford Fiesta? Had the alternator and battery checked yesterday and both still we're good. My car is dead in the morning after being parked overnight. Any recommendations will be helpful. Thank you in advance

When I had the battery and alternator tested yesterday I was told that battery was still at 95% and alternator was steady at 14.5

If the battery is dieing from just SITTING, you likely have a short somewhere. If the battery dies after some driving and can sit relatively ok, your alternator/charging system is malfunctioning. Do this, get a battery charger for your car, charge the battery, and when it's done measure/record the voltage when the battery is disconnected from the car and connected to the car. Then turn the car on (that is engine running) and measure/record the voltage again. Tell us what numbers you read and we can have a pretty good idea of what's going on. If voltage drops when the battery is connected to the car you have a short. If voltage drops only between battery connected and engine on, your charging system is shot. Good luck and let us know!

I just went through this with my van. Battery died with the van off and the radio on for more than 5 minutes. Literally jumped it all the time. I replaced the battery, battery didn't work. Found out it wasn't charged when I bought it (as a lot of places don't pre-charge them now) so I charged it and it worked fine. Check with the place you bought it from and ask if all batteries are pre-charged. If not, bring it to them to charge it for you if you don't have a charger handy. Double check all the fuses are good while you are at it.

Secondly, if the alarm/starter is aftermarket or was installed by anyone other than a professional alarm installer, you very well might have something draining the battery constantly. I hear more problems from people with alarms than anything else when it comes to dead batteries.

Thirdly, once the battery is charged, the voltmeter (read the instructions how to check voltage with DC volts) should read between 12 and 13 volts across the battery posts while it is running. This indicates the alternator is functioning. If you shut it off it should be just about 12 volts. If you test it again in about 30 minutes and it already falls below 12 or 11.5 volts, there is definitely something draining it. Lastly, check to see if the glovebox light is on, or some odd light in the back of the car or in the trunk or what not. Sometimes all it takes is one little light to drain a battery. Or a faulty install of an alarm system...

Just for sake of safety, make sure the connectors on the posts of the battery aren't corroded. Use just plain ball bearing grease or vaseline after cleaning them with a wire brush (or replacing them altogether).

Good luck.

I had similar problem with car battery dying when not used for three days. Found out that the car radio is draining the battery even when not "on". The radio was connected "before the key" i.e direct to the battery. In another case I also had a battery drain dead with a radio ON within one day.

think this is my problem but how to fix it - does it mean car radio wiring error?

Did he also then tell you to purchase and use a battery maintainer to keep your battery from dying in the future? I have two of them, on on my pickup which is rarely driven, and the other on my Harley. A maintainer is a lot cheaper than a battery. And don't just buy a cheap piece of junk maintainer (trickle charger) from Harbor Freight. Buy a decent Schumacher battery maintainer that will actually do a proper job. Also, start with a fully charged battery before hooking up the maintainer as it's not meant to charge a weak battery, only to maintain a healthy one.

What if my charged up and disconnected (NEW) battery is at 13.1 volts in the evening, then is down to 12.4 the next day (~ 12 hours disconnected from everything but thin air).

Is that normal?
