8 months battery life is pretty poor. The ones legislation requires on cars and is about to require on trucks are guaranteed for two years and I know of ones that are working at 5.
You don't need the Baud rate maxed out, tyres go down much slower than electronics react. Cut the repeat rate and the battery lasts longer.
I expect bike technology will get up to speed once the hobbyists are out of the market. Most tyre manufacturers intend to mount car and truck sensors in the tyre wall to corner the market. The instrument makers will take the receiver end on light vehicles. At the moment there is chaos because the market is full of wannabes and amateurs trying to sell complete bolt on systems. I'm sure bikes will follow.
Sealed is better BTW, the air in the tyre is pretty wet because workshop compressors generally lack any form of dryer.
