2006 IS250 battery casing "sensor"?
Original battery is dying (I think) so brought it to a battery shop. The guy looks, strokes chin, and tells me he's reluctant to change it as he did not fancy removing the "sensor" connected to the side of the battery casing, as it might control, or reset something - recommended taking to a lexus dealer and pay the full whack!
Anybody know what that connection is... I think I read it described as 'positive leads' (in a thread I can't now find).
Anyway - since getting this feedback I looked up other solutions and will try the distilled water etc. but still will want to remove battery so want to be sure that the 'sensor' can be disconnected without damaging anything.....

I assume he's talking about the current and/or temperature sensor(s). They won't have issues with the ECU. Nothing special required when it cones to those.
It's an easy change.

AS Jeff said above its a temperature sensor.
Comes apart relatively easily ... a small screwdriver is handy to depress the release tab.
It has to be disconnected to lift up the battery cover.
Just re-connect it after new battery fit and all will be good.
If you get a new battery just ensure you get the right type with the posts on the correct face.
I assume your battery is on the rhs of the engine bay by the bulkhead, looking from the front of the car
In the UK it described as type 068 with the posts at the back edge. If you get a type 069 the posts will be at the front and the leads will be over-stretched to reconnect...not good!
Many UK owners opt for the Bosch S4 026 068 because they are very good batteries and can be obtained at very good prices. I have one myself and it fits perfectly.
Hope that helps.

Quite right (some say that about the car too)
Replaced battery this morning. For anybody this side of the poond.. Halfords did it for less than half the price of the Lexus dealer, and give a year's more warranty.
see here https://www.lexusownersclub.co.uk/fo...ery-for-is250/
I ended up getting a Bosch S4 026 ( which most parts sellers sites states will Not fit!)

can I ask what battery exactly was it that Halfords fitted for you as the IS 250 battery is not usually on the shelf and they fit the next best fit!

Their own brand HB030. (not certain but they may be made by Varta).
Fitted perfectly, and comes with 3 year warranty (Lexus only giving 2), so, seems like a good deal to me!
