C6 TPMS battery replacement
Here's a few pictures of the C6 (European market) Corvette tire pressure sensors with the battery exposed. North American C6 Corvette sensors are identical although they transmit at a lower frequency.The battery is the same diameter as the C5 sensor battery but it's thinner. The model number is RENATA CR2450N. It is a 3volt Lithium battery. http://www.renata.com/pdf/3vlithium/DBCR2450N.04.pdf
The steps taken to replace the battery is documented here http://forums.corvetteforum.com/c5-t...-tutorial.html Watch the "You Tube" video to see if it's something you might want to try. The batteries are about $5 each.
The C6 battery has a rated output/capacity of 540mah while the C5 battery is 1000mah. Order the batteries with a "PC Mount" configuration. If they aren't available with the legs spot welded on (pc mount) then apparently some battery vendors can add the legs for you at their store.

thanks man! you just saved me over 100 bucks on two new sensors!! my left front keeps going to 0 randomly.
now it does suck needing to demount and remount the tires. $$$ any tip for that?

2450 is a standard lithium battery...you just need to get the ones with the contacts welded on.
That would be called a "PC Mount" battery.
This sensor is red or orange though, I think the current sensors are gray, so it probably would be best not to buy a new battery until it is determined which battery is inside the current sensor.
BEZ06 needs to chime in here.

Here are the new batteries and the rest of the installation. The link to purchasing the batteries $2.00 each http://ca.mouser.com/Search/ProductD...4-CR2450NFV-LF
Battery contacts soldered. Hot melt glue holds the battery in place.
Right Stuff used to fill in the void. Potting compound would be better.

There have been several people posting that just breaking the bead will work on normal-profile non-runflats, but the stiff bead and sidewall of the low-profile C6 runflats makes it very difficult or impossible.
When I needed to change a sensor on our 2009 (Michelin PS2 ZP runflats), a pretty sharp Discount Tires shop in our area said they would not try the "easy" way, they just dismounted the tire (or maybe the bead on only one side) for the swap.

If you reapply the sensor to the same wheel position I don't think that would be necessary.
The grommet seals should be replaced for peace of mind.

Not calling you out, but have you actually done that?

Scroll down to and you'll see this picture:
I don't believe that is a runflat, but the power of a tire machine can easily push down a runflat tire just as much as you see in that picture.
The manager at my local Discount Tire has a Z06, and he says it is no problem for their machine to push down the bead of a runflat enough to reach in there just like in the picture above.

There have been many reports here on the forum that you can simply break the bead and remove/replace the sensor without totally removing the tire from the wheel.

That is one of many reasons we make machines to make our life easier.Machines feel no pain.

By the way Bob, Coast Guard Rescue Swimmer made a rescue here yesterday on one capsized boat.

A big "Semper Paratus" salute to that Rescue Swimmer!!!
I know that at least the 2005-2009 C6 Vettes that were built for delivery in Europe had a different TPMS computer in the car than the ones built for the U.S./Canada market.
All domestic Vettes (2005-2013) use sensors that transmit their signal to the TPMS on 315 mHz.
At least the 2005-2009 Euro spec Vettes used that orange sensor, and it transmits on 433.95 mHz. I don't know what the Euro spec Vettes built in 2010 or later use.
The gray sensor used in 2005-2009 domestic Vettes is gray with part# 25758220.
The last digit of those orange sensors is different: 25758221
I imagine they all use the same battery.

I just recently left the tire industry after 10 yrs, but it takes 20 minutes or less to install all 4 new sensors on run-flats. I've done tons of Vettes over the years.
Sensors run between $45-$120 each. And some places charge for Mount/Dismount/Balance. Even just breaking the bead can knock the balance off.
If you have the time to bring your wheels up, dismount or break the bead (which still isn't 100% balanced afterwards), take the sensors home, rebuild with new battery, bring wheels & sensors back for install, and then take them back home to install on the car then this is a great option.
So, is the little money saved or the hassle more worth it?
