Thanks for the information. Looks like I will have a huge paper weight and will need to buy another charger.
Back about 10 years ago, I bought about 6 Astro Sabers, 1 at a time. After the 2nd one, I told the sellers I did not need the NTN4734A charger, but would pay the selling price, just don't send the charger. Well each seller sent the charger anyway, because they probably wanted to get rid of it too. A few years ago, I offered to give them away for free to locals, or just pay actual shipping to get rid of them, as I can't throw anything away. No takers. One I remember was still new in the box from the State of Indiana. But the newer tri-chem, or Impres chargers are so much better, & charge Jedi's, Sabers, XTS, & XPR batteries. I even have a few STX chargers where Motorola made adapters to charge Sabers in STX chargers. But all these old chargers while built like brick houses, were only good for ni cads. Cooked them pretty good too.
