My battery failed me after 2 years into a 4 year guarantee. The garage replaced it then 7 months later it died again. RAC said that garage had given me too small a battery for a 1600cc diesel car, and the battery at 450 amps should be 600. The RAC fitted a new battery after saying they could charge the battery up to get to a garage but it would not hold its charge should I switch the engine off. It was completely dead.

I took the old battery back to the garage but they said it is the correct battery -although it was moving about in the casing which RAC said was dangerous - and charged it up again. I explained to the manager that I was told by the RAC that it would not hold its charge. They wont give me any money back but how can I determine if I have been given an incorrect battery in the first place?

I now have two batteries!

Simply put, look at the specification required for the battery in your car. It will have a code number which will determine both the size and shape of the battery as well as the capacity (Amp Hours or Ah). If the battery they have sold you is of the right number then it will be compatible and the garage will be correct. If not then the RAC guy is correct.

If as you said the battery isn't mounted firmly then it's unlikely to be the right one but the code number is key.

What make/model/age of car? - if it isn't in the handbook, a check on various motor factor sites will tell you which type it is.

Just because it moves in the battery compartment doesn't automatically mean that it's too small. It depends on the model but, whatever it is, it should be held secure where it's fitted by the original fittings.

Eta, just seen above posts - too slow typing.

Thanks for that. I'll look for the code. I have just been told the actual dimensions should be of importance too. As the battery didn't fit the casing I'm hoping I can get back to the garage fuelled with some knowledge!

Hyundai’s do tend to have smaller batteries when compared to other manufacturers so yo may find what the original garage fitted was correct.

Was the battery the garage supplied a decent brand - Varna, Bosch, Yuassa or was it a poor quality Lion ? The warranty would have started when you purchased the original battery and you may find that they would only replace and not refund. Suppliers of batteries do everything they can to avoid the warranty

For any Kia or Hyundai we will only order a battery when we have seen the car to ensure we get like for like.

Has anyone mentioned that a loose battery will shake itself to bits and warranty will be void?

Whoever left the battery loose is responsible for 2 reasons

1 - Should have known a loose battery will shake itself to bits

2 - If it didn't fit correctly.....

Does the supplier know that the battery was loose, that is the question

Enter your reg into Tayna's website & see what comes up.

I've had a couple of batteries from them for our own cars & would use them again.

I've used them a few times. Excellent service and next day delivery at no additional cost.

Sounds like a parasitic drain is the root cause. Get an AVO on it.

My 1200 cc ( 600 a side ) motorbike has a battery the size of a Tesco sandwich and that chucks it over no problem.
