We had a very similar problem at SMA.

System was purchased 2nd hand with the original transponders (3-5years old).

TJ had used Jeff's services in the past, so off to Brisbane with the Transponders.

I can say the service was first class and would be more than happy to highly recommed Jeff to any club that needs Batteries replaced.

We decided to send all 20 transponders and had them back by the due date.

If you have any questions, please PM, beter still go to Jeff's site:

www.users.bigpond.net.au/bigfix/transponders

Our repaired transponders recharge faster and have lasted up to 18+ hours off charge.

Cheers,
