Default Battery Dies Too Quickly

I have an RX400h and the auxiliary battery dies after a couple days. Last time I went out of town I came back a week later to a dead battery. Went to Lexus and they replaced it. That was about 2 months ago. This weekend I went to Phoenix for 4 days and came back to a dead battery again.

Anyone have any ideas? A better battery? Maybe a retrofit for a regular size car battery?

Try the Costco battery that fits the RX400h. It's about $70 and has a 100 month warranty. I've had mine for 3 years now.

Mine will discharge if I let it sit for about 2 weeks, especially in cold weather.

We can leave ours in the winter time for 1.5 weeks with no issues. Always parked inside the garage (non-heated but insulated).
