That's it. A few days ago, I decided to find a supplier for the Tadiran batteries. I came up with EVS Supply in Richardson TX. They have hundreds of the Tadiran TL-5101/P (the one with wire leads) in stock for $7.77 each. I ordered two online (they also have an 800 number) and for $15.54, including priority mail shipping, I had them two days later. The TL-5101 (no leads) for Macs is a bit cheaper. Great price, great service... http://evssupply.com >A few days ago, I decided to find a supplier for the Tadiran batteries. >I came up with EVS Supply in Richardson TX. > >They have hundreds of the Tadiran TL-5101/P (the one with wire leads) in >stock for $7.77 each.
