Android radio problem or not

[DXP55]

I have a 2010 Ford Focus 2.0ltr TDCI Powershift with keyless start.

I am on my second Android radio now - first one playing up and seemingly draining battery over a few days - Put old radio back in and seemed fine - OEM radio was also faulty -no USB or disc playing so got a new Pumpkin Andriod on 7.1 - A vast step up on old Android - So once again I am getting battery drain - Because we don't use car daily but I have to start it to move it out of garage then put it back the battery gets a hammering.

The connections on radio are if I remember yellow for the permanent positive and red for switch 12v feed - because it's keyless there is no ACC or ignition switch - With ignition off the radio will not turn on - turn on ignition and radio becomes live - That says to me it's got a switched live red wire feed. Proved with a multimeter - no ignition no 12v -ignition on +12v

The other week I took car in to have battery tested - the young lad said it's showing fine but needs charging - Now this car has a build year of 2008 so that makes battery 9 years old so what are the chances a cell has gone or whole thing is on way out - I am really tempted just to buy a new battery as winter is almost up on us - last thing I need is neighbour over the road having to come jump start me like he had to yesterday.

I now put battery on charge every two days - I think I am baulking at £140 ish cost of new battery.

That is my thoughts exactly at the moment - My old one was Xtrons - At the moment the car is in garage - I have operated the bonnet catch so it's closed - then closed and locked doors and set the alarm - I am now measuring the voltage across battery for next 4 hours - Will charge battery over night then disconnect radio and test for battery drop again - Hopefully it's battery as I am totally fed up of having radio in and out like a YoYo - My problem is I don't use car every day.

Charged my battery up yesterday and reading said 12.5v - - left meter on all night with car locked and this morning it read 12.35v - Mate over the road checked his spare battery and that showed 12.35v and said if I connect this to a car it won't even turn the engine - mind didn't either this morning - So bit the bullet and ordered a new battery as mine is at least 8 yrs old.

If you put a switch in the yellow wire that is the permanent feed to radio - in my case the only thing I might lose is radio stations -not got anymore settings programed in. - I thought about connecting yellow to the red switched wire.

I know yours isn't a Pumpkin but this might help http://www.autopumpkin.com/forum/viewtopic.php?t=161

Will update when the new battery is in.

Had a new battery fitted on Monday - used car Tuesday so last night I locked it up in garage - took a battery reading of 12.71v - checked this morning and now on 12.56v - this is much better than readings from the old battery and also the Android radio is still connected. - Going out soon so will see how well it starts.

Battery was booked in for last Friday but battery was too tall in battery box and clamp didn't fit -(never knew it was a MOT failure) - So they got a smaller battery and that was too tall hence Monday fit as they then had to order it. -- Bosch battery 80a -680a - Fitted and a electric test which nothing untoward showed up for £145 - The last battery I purchased was £43 for my Mazda 626 V6 GT.

Cars are fine these days providing nothing goes wrong and then dig deep in your pockets.
