I need help! My battery went dead last week as my td5 has been parked up for a while, I removed the battery and charged it up then refitted it now I have issues with arm and starting process?.. When press lock on key fob horn beeps once but doors won't lock (all doors are fully shut) also when key is put into the ignition barrel it starts straight up on first click without getting to second sprung loaded click? Can anyone help me out here? Thanks

well the battery is now dead (or only discharged !)
cause #1 ALT/Gen replaces WRONG, see here 10,000 times. more www.

driving a car the ALTERNATOR produces all Electrical power.
100amps x 13v is 1300watts, and runs ALL>
when it dies the battery is sucked dry/dead/ discharged.

1; remove neg lug from battery or BOOM (100amp fuse BLOWN)
2; remove ALT
3: new one back connected same.
4: battery NEG lug back
bingo no BOOM.!
every SM manual of every car tells that;.

you said didn't want to start
but I guess you meant starter is dead, or clicks only or will not spin fast as it must.

the 15mins is dead accurate, for 50 years driving seen this happen
as ALT goes dead at night,
in the day engine runs 30min to 1hour dead ALT , HEADS off

the blow fuse is just bay fuse
or worse, a fuseable link, oddity not fun to fix. ever.
thus step 1,

no engine told but let me look on uSA car thjis.
2010 not AVEO5

there it is but what it looks like, hummmmmm

Do you mean that it goes dead after sitting a week or goes dead after a week while driving it?

You could have a parasitic drain. Something that is left on in the car and drains the battery. It could also be a corroded terminal on the battery where the alternator is not getting power to charge the battery . Clean the post and the connector of all deposits and install those felt washers under the terminals to impede further corrosion.

sounds like a bad battery or a bad connection

Jumping a dead battery is a dangerous practice
You have to fully charge a dead battery before
putting it back in service
Have the battery tested
Get a fuse cover from a salvage yard

Your altenator is out. The car was running on your battery until it went dead.

Running so few miles has accelerated the aging of the battery - the battery never had a chance to fully recharge in such small trips -  so now you have to replace it a year sooner than usual.
Just replace it.

If checking battery cables and wiring to the starter and ground points doesn't help. Have the battery checked for a bad cell. Preferably before you charge it.

any battery that sits has the potential to drain. when storing your vehicle, remove the negative terminal from the battery. this should aid in keeping the battery alive. excellent vehicle. enjoy driving it. by the way, make sure you get the proper battery for either the L6 or the V12 motor. it makes a world of difference in the long run.

Probably the battery. Take it the chain auto parts place and they will test it for you.
