08 LS 600HL Starting battery - to replace or not?
I have a 08 ls 600 HL.
The dealer says battery is in good condition but I am not sure I want to keep the battery for longer than 5 years.. Not worth the headache if it does not start at the wrong time.
Typically, is the dealer's diagnostic print out of the batter condition, reliable?
How long do these last? Have any of you with the LS 600 had battery failures? I am in wisconsin.
Have any of you replaced the battery yourselves? Someone said that disconnecting and replacing the battery might cause certain electronics to reset their memory. Is that true?
Thank you.
Edited 8-18-13:
The replacement from sewell in dallas is much cheaper - like $450 or so.. update: sewell cannot ship anymore.. their website was incorrect for shipping charges of $10! it costs them $120.. Also, local lexus dealer is quoting only $400 now.. Vs more in the past..

Lexus Master Tech here, If the battery print out looks good and healthy, and is no where near the replacement mark, then I would have no problem driving the vehicle. Just make sure that the test slip that you received is that of a genuine Lexus/Toyota tester, as it has the stock CCA built into it. If if is, it will have your make and model on the test slip, otherwise the tech could just be guessing.
The auxiliary battery on those vehicles can last a very long time as the only thing they have to do is keep the vehicle's memory when turned off, uses the smart key function, and connects the relays that connect the hybrid battery to the rest of the vehicle

They said mine was ok after 5 years and 1 time (that I know of personally) it dying from leaving the car on, but I still took the initiative to replace it anyways. You can find a nice optima for half of the OEM battery and much better specs. Im running a Non-OEM battery and after market sound with no issues

Also, while changing the battery, do we have to like keep power always on.. such as connecting them both in parallel to keep the electronics on standby powered up and then switch between the two?

I am referring to the battery that is like the typical car battery, in the trunk of the car. Is it not this battery which starts the car? Some one told me that this is the battery which actually turns the engine on/off. Not correct?

When charging the battery, just turn the vehicle off as you normally would, and connect the charger, and charge at the absolute lowest rate possible. If the auxiliary battery is charged too quickly, hydrogen gas could give off too quickly, and it has the possibility of exploding.

Interesting about the Optima..I notice my trunk battery has an additional wire connection but not sure what that is for and if aftermarket battery had that same connection?

Yes, the one that looks like a typical car battery is the auxiliary battery. The hybrid battery actually starts the car, the auxiliary battery just connects the relays that allow the hybrid battery to work. It is a completely different battery than a regular lead-acid battery though.

I left the car on with my aftermarket sound in the parking lot for an extended period of time and it died requiring a jump start from AAA. After 5 years and that normally a battery would not be at 100% yet Lexus said it was which may or may not be true, but I took things into my own hands. The OEM battery was very good regardless I just wanted more, but I did not go Optima I went Die Hard from sears. The optima had higher CCA but still less RC than the die hard, both had more CCA then the OEM panasonic battery so the only thing I cared for was RC for my aftermarket sound

As someone else asked.. what did they do with the third wire at the battery? (I think it has to do with battery temp).
Also, there is a vent tube for the existing panasonic. Would the die hard need it? I think die hard is a sealed battery, yes?
I went to sears online and they suggest this battery: DieHard Gold Automotive Battery - Group Size 27F (Price with Exchange)
Sears Item# 02833128000 | Model# 33128
At $119, its cheap.. I would have it installed, if you say that not using the 3rd wire was not a problem. Did you have Sears install he battery?
Thanks

I honestly dont know what they did with the 3rd wire I was unaware it had one they just switched it out for about 130 after labor no issues what so ever and very quickly. That is the battery I have.

update: I just disconnected the 3rd wire from the panasonic. Started the car and PCS warning light came up. "Check hybrid system" warning came up. I disconnected the batter and reconnected everything and the lights went away. I checked the resistance of the "third wire" harness. It showed 1.94 K ohms resistance. Did they close the circuit of the 3rd wire harness in your car - with a jumper wire, for example? Could you please check? Because if they left the 3rd wire harness circuit open, you would have gotten the warning lights. Thanks!
