Battery questions for 2002 Alphard 2.4 FWD

[bellum]

Morning All

I have just bought a low mileage 2002 Alphard 2.4 converted day camper as my first foray into camping to see if I like it!

Went to go out into it today and the key is clicking multiple times but not turning motor - the air conditioning, radio etc are all working fine.

Leisure battery is flat but looks like it is disconnected from the car battery.

Upon looking at the fitted car battery type it is a well used Yuasa 3053 45Ah 400A.

On the Yuasa battery site it recommends a battery of 60 to 65Ah and 500+A.

A quick look on a couple of other battery sites say similar things.....

Not being an expert.... would putting a recommended battery in make any difference to the running of the vehicle positive or negative?

Anyone aware of what the correct battery would be or works for them?

I will have a go at jump starting in the morning. If that does not work then I guess its handing over to a mechanic who could test the starter motor and I guess alternator.

But it would be interesting to understand thoughts on the battery and why it may potentially have the wrong battery in it....

Thanks for any opinions.....

Welcome Steve sounds more like a battery issue have you tried charging the battery

Thanks Lee, not yet, will try jump start today and then may consider charging the battery.

Am still interested if the correct battery is in this at the moment.

I agree with Lee; suspect battery.

 

Tayna Batteries is a good mail order supplier.

They will ensure the the terminals are in the correct position, the correct size, etc.

 

Be REALLY careful when changing the starter battery, reverse polarity, even for a moment, will blow fuses.

 

The bigger the better, ensuring it will physically fit and can be held in place.

The CCA is important for our upcoming winter.

 

The fact that the leisure battery is disconnected could be just isolation, but will prevent the alternator and split charging system from operating !
