How long on the original battery?

Wow, that's a long time. 6 years and it is pretty cold out there!
Mine is 6 years, too. So I have been patiently monitoring...
Still have to find a good replacement for it. I want the Kirkland brand at Costco but can not find the right size in my store.

What are the other battery options we have? I think I can fit a different one for the RX from a catalog battery at Costco. I will let you know what it is.
The replacement one has higher cranking amps. I do not think it is an issue. Right?

I own a 2005 RX 330 and I'm getting ready to install the second replacement battery. I'm pretty careful to not leave things on. Anyone else having a lot of trouble with battery life in their RX330?

A simple test of your battery can be done with a volt-meter: 12.0 volts or above is good for a fully charged battery in good condition, checked with the engine off, across the two battery terminals. It is a no-load test, meaning that under load the battery voltage may fall off substantially, but, though not foolproof it's still valid. A battery going bad will show lower voltages, and one with a dead cell will show significantly lower voltage, about 10 volts for one with one bad cell.
For those not permanently-sealed batteries, low voltage readings are usually an indication that you need to add some distilled water to the cells before they begin to warp, short out, and kill a cell. Buy distilled water at the grocery store where it's sold for irons, by the gallon, cheap. Not using distilled water will shorten a battery's life by adding minerals (ions) to the electrolyte (the liquid in the battery) that will build up on the plates and eventually short them out, again, killing one or more cells.
You can check your charging circuit by reading the voltage at the battery terminals while the vehicle is running. Again, this is a no-load test, but reasonably accurate. Normal voltage at the terminals should read about 14 V, plus a volt or so. Too high a voltage will cook a battery; too low a voltage will not charge it properly.

05 RX330 with 118,000 miles and original lexus battery. last night i had the cargo lid open with the engine turned off. the headlights were on auto so they stayed on while the cargo lid was open. it was for about 5 minutes. i tried to start the car and it would crank but very weak and would not start. Time for a new battery.

Original Battery in my '05. If it sits for any extended period of time, I put a battery tender on it. Battery still tested as near new condition last time I had my mechanic check it, back in August.
