Bat'ry Gard TM

Costs less than one set of batteries!

Bat'ry Gard has invented and patented a locking device for the battery compartment of calculators, CBL's and the new LabPro. This prevents battery theft from these devices. Stealing a calculator, with Bat'ry Gard installed would be of no value since one cannot use a calculator with dead batteries.

Since Dec 1999, Texas Instruments has changed the battery compartment on its TI-83+ calculators. Check the date code on the back (use the first four of the last 5 numbers - eg. 05981 is May 1998). If your calculator is a TI-83+ and the date is 0999 or later, order the Bat 30 plus or the Bat 100 plus.
