TST tire monitor

As Dennis said, "NO". The batteries are not easily changed, and opening up the monitor or sensors pretty much destroys them. If you call TST, they will offer you a pretty nice deal on replacing your 510 system with the newer 507 system that does have user replaceable batteries in the sensors. Not the rechargeable battery in the monitor though.

510..NO....507...YES.....Dennis

The Moniter is the one that goes on the dash not the wheels!

I would ask Here
The owners of the company monitor and reply on the forum. Pretty cool. :C

the ones with changeable batteries have a small plastic plate on one side with 2 small screws. If yours has that you can change the batteries.

Just give them a call, they're very helpful.
