Is there anything I need to do when changing the battery for 2010 Lexus RX350?

[Ginnie]

My battery went dead so I need to purchase a new one. Is there anything else I need to besides replace the battery?

Always disconnect the negative terminal first and replace it last!

Would be prudent to wear safety glasses in the event of acid escaping from the battery, so also wear some gloves to protect your skin.

Apart from considering changing the Key Fob battery if it hasn't been replaced recently then it should be good to roll once everything is programmed back in

Good luck and let us know how it all goes

Thank you for the ideas. The key fob battery has been replaced recently.

Also, if your dead battery is less than 3 years old you may be able to get credit for any remaining months left on the warranty. Check the date sticker on the battery.

Costco and Walmart are my favorite battery vendors, in that order. When I pick the battery, myself I get the newest battery based upon the date code.
If you are planning to change it, yourself, you will need to relearn window operation. See your owner's manual for details. If a dealership changes the battery, they should do this for you.
