    did you get the correct spec battery? They can differ hugely in ouput.

    The bigger ones are generally more heavy duty and have a higher cold crank output. I'm not a leccy but I think that means they can deliver more if asked. The voltage should still be the same.

    Either way, I'd get a proper spec one and take it from there.

    ECU would be blown by now if it was going to be an issue imo.

    Maybe worth checking the alternator voltage output....should'nt be
    putting out more than 14 volts-ish...:)

    Battery size isn't your problem, get your alt checked as advised above. An overcharging alternator will give you bright lights, bulb failures and will destroy a battery.

    i'd agree with that because the night it went dead .I was using the radio for 20 mins. Trie to start the car and it died. The battery is double the amps of the original .

    Big difference between a sub-spec battery and an over-spec one! One causes problems, the other does not.

    Yep, sounds like an alternator issue.

    Provided you have the correct voltage (12v in the vast majority of cases) and at least the minimum required CCA (Cold Cranking Amps), the total CCA capacity of the batteries doesn't matter. The more CCA you have, the bigger your 'reservoir' of available current and the longer you can keep electrical items running before a failed or faulty charging system brings things to a halt.
    From an electrical point of view, the size and shape of the battery is irrelevant.
