My 12v Battery isn't holding much charge and this recent cold weather seems to have almost killed it off - requiring a boost charge every 2 or 3 days if I've not driven the car.

So - as Lexus appear to want £300+ for a new (Panasonic I assume) Battery "ah but it has an extra connection that other similar batteries don't have Sir"... can anyone recommend a good replacement that's available at more reasonable cost?

I'm currently looking at the Bosch S5 AGM range - though a direct size for size replacement doesn't seem to be available (going from Google info, I've yet to measure and properly check specs of the existing OEM one).

I obviously realise that I'll need to move the temp sensor from old Battery to new - but have heard good and bad stories so looking for anyone who's in the UK and has done this with a good result.

Any help appreciated.

Have a look at the Exide Edge range of AGM batteries. Also although this sounds a bit off the wall I use a mobility scooter Battery in my GS450H. These batteries are designed to withstand deep discharges on a daily basis. They also generally have a much higher amp hour capacity size for size against other batteries. They are available on line, and from some Battery outlets such as The Battery Bay at Cannock. The batteries do not have standard terminal posts, but standard adaptor post can be bought and fitted for a couple of pounds.

I also used a mobility Battery in my Prius a very tall thin Battery, and was able to find a Battery of the same dimensions, but with 30% more capacity. If you are disabled no VAT is charged on mobility batteries.

If you can measure the Battery tray I can give details of suitable batteries.

A PO355 code relates to a faulty ignition coil or it's connections.
