Hello everyone,

I have a Lexus CT200h since 2017 (with 60.000 km), my experience is good and every year I have checked the vehicle by official assistance.
Last friday I powered on my Lexus and I see the error "P Lock malfunction" and "Aux battery low warning", try to restart the car and become ready (after some minutes). Before friday I haven't use the car for 6 days.
Next day, saturday evening I try to start the car and same error: P lock malfunction and Aux battery low warning, try to wait some minutes but it doesn't work. The next morning with my dad's car I had "jump start" the car.
After this I have use the car every day without problems.
I have try to ask about the problem to two mechanical (one official and one "generic").:
Official (by phone): "you can monitor the situation and if the problem happens again you have to replace the aux battery (300-350 €)"
Generic (on-site): he checks the battery and suggest to recharge it and check if the problem happens again.

I prefer to replace the battery but I would try to do myself, the problem is that I have problems about how to find the correct battery. I know that I need AMG Battery (I prefer GENUINE) but there're various models and prices.
For example those types: https://www.espertoautoricambi.it/le...10142/batteria
I tried to ask the replacement for some local vendors ("Norauto" or "Beps") and they not sell it..

I also find this: https://www.ebay.co.uk/itm/383360062113 but with shipping cost I think is the same than official assistance.

How can I find the right battery and/or where? Can you suggest some Italy or International store (also ebay)?

Thank you.

My car has been running for years with just a standard battery (not AGM). I have had it for 2 years and it was in there when I brought it.

You really should have an AGM battery or one capable of many discharge cycles. The OE battery looks to be made in Korea but why are so many OEM Lexus batteries dying? I would buy the Exide before the Lexus one.
