Replacing the battery

[TyrannosauRoss Lex]

Hi guys,

I have just had the Battery replaced on my LS460 because the other day after being left for just 4 days it took a while to start (about 2secs more than usual) and after a run it started fine. 2 days later when it was cold (5 degrees celcius) it again took longer than normal to start. I have just had a silver/calcium 850cca and 95Ah Battery fitted, which is basically the best spec available for this car I think. My question is someone asked if it needs "coding".....but the car starts and drives fine so I'm assuming it's fine to leave alone? This was the case on my old BMW E65 745i, I bought a new Battery, never had it coded but 2.5 years later it was still working fine when I then sold it.

Thanks

If your car starts and performs as normal then the answer is no. 👍

The process is not the Battery per se... but restart procedure for the ignition key/anti-theft device.

This kind of info should be in your Owner's Manual.

I never remember the process for my Mk4 Lexus LS400 and interesting to note the procedure is detailed in a yellow warning sticker on the back cover of the Owner's Manual! Looks like they wanted to draw attention to it...or someone forgot to write it in to the manual. 😮
