12V Battery replacement!

Hi all, I have a 2004 2.0 Rav4 XT4 Diesel D4D, Exactly what type of battery should this have? My present battery is taking about 3 turns of the key to start the engine, I think it has been on from new about 7 years so must be due a change! Also how do you remove the battery from its compartment (under the cover) I know the sequence of lead removal!
Do you lose any radio codes...etc? Do you have to inject 12v from another source whikle the battery is removed?
I have the user manual plus a Haynes but both are very vague in this area!

Regards, Steve (UK)

Pretty sure yours is the same as mine, use a coin to remove the plastic tabs on top of the shield(near the wipers). Once off, you have full access to the battery.

If you can use some small battery loader to keep up the volts, there is no harm of it. Then you won't loose either any codes, clocks etc.
I guess you can find with around 30 GBP nice loader that can be useful otherwise too.

But to my knowledge, problems caused by sudden ampere peak when putting new battery on, are more often in German cars of starting of this age.
2003 Corolla had no problem when I swamped battery old style.

Radio is not coded, but you might loses the clock and the engine adaptations, leading to a lumpy idle for the first 80-100 miles.

The best place to buy batteries is Vauxhal main dealer, they are rebranded AC Delco premiums. You want the reverse terminal (positive at the front left), a 70aH is ~£96 inc the VAT. My local place does not have this arrangement in stock but it arrived next day.

If you don't get a reverse terminal, this is what happens, the +ve is in the wrong place (rear left) and the +ve cable is just a little too short to be comfortable. The cables are stretched and very hard to fit, and the red cover no longer fits also.



I've now changed this battery.

Thanks for the photo's and info! What are 'engine adaptations'? Did you get a "lumpy idle" when you changed yours?
My 54 plate Rav is the diesel engine, I needed four cranks with the key this morning so I think it may be time to change the battery soon! Does anyone know the name of the original battery that was supplied with these cars when new cos I think that one is still on after 7 years!!

Probably a Yuasa. Also good batteries.

Engine adaptations are the things the engine ECU learns about how your engine components age and it attempts to compensate for them. Yes mine is lumpy for the first 100 miles (I pull the battery a lot for my DIYs), it's a petrol.
