Battery Dead

[cooper12000]

hi I drove the car yesterday on two short trips. today I have gone out to the car and the Battery is flat. it just about caught the first time of cranking but died.... second time it would barely turn over. If it is the altenator what is the procedure to change it. can it be done fairly simply at home or does half the engine have to be dismantled.

many thanks

get it done to Halfords or a similar place they do free Battery & alternator checks. it will measure the CCA of your current Battery, if you do need another Battery try eurocarparts or online.

charge your Battery & then get it checked. if it was the alternator then a warning light should have come on.

You didn't have a light on or possibly a short?

no lights on.... got neighbour to jump start it and took it for an hours drive.... put a multimeter across the Battery and got 14.2volts so alternator ok.... if the Battery goes flat again I will have to get it tested.

many thanks

I would look at Battery first if its original its probably had its days.

Battery is knackered... I went for a drive sat for over an hour. didn't use it at all yesterday went to start it today Battery is flat. that lead me to a few questions

1) is there a shut down procedure for the ecu for b4 I disconnect the Battery

2) if I cant find the radio code b4 I disconnect the battery is there a way of finding it

3) where is the best place for a battery as the cheapest I can find is 70 pounds

many thanks

2, no codes on t25 avensis radio's as far as I know, had mine and others out never been asked for a code.

3, I use a company called andrew pages got a 4 year Bosch (blue) for around £60.

euro is a good start as advised by konrad also use tweet5 (promo code) to get 5% off

afaik the radio/satnav is coded to the ECU so there is no need to input a code manually.

remember the safe Battery removal rule of thumb

on Battery removal

remove neg terminal first

on Battery fitting

fit neg terminal last

sorry if I sound patronising
