Default 2004 RX 330 battery drain

Hello all,
I have a beautiful 2004 RX 330 with 168k miles in amazing condition I’ve owned since 2007 and the past couple years it’s not driven very often and the battery will not not allow it to start after about 4 days of no use and looking for suggestions as to what could be causing the drain. Thank you

it could still be the battery, auto parts stores will test it for free. But when you do start the car, how long do you drive it? Maybe you don't run the car long enough to fully charge the battery.

Highly suggest you install a battery maintainer, $50 investment that will prolong the life of your battery if your is not a daily driver. Good luck. Both my non-daily driver cars in the garage are equipped with battery maintainers. When not in use, I plug them in. It will extend the life of your battery, guaranteed. Saves you money in the end. It costs $50 for a good trickle charger.
