ONE Replacement for Marantz, Philips, RU950, RU960, RU970, RU980, RU990, TSU3500117, 700mAh

Twice before I have ordered a battery on Amazon that was supposed to be compatible with the TSU-3000, but neither were. The charger wouldn't charge the battery, probably due to a missing internal thermistor that the charger requires. I'm happy to say this battery works just fine with the TSU-3000, really glad to be back to good battery performance.

I made an unfair rating… This is exactly what I ordered, and it arrived in a timely fashion, It just didn't work for me. I knowingly ordered the 700mAh battery even though what I needed (and still need) the 600mAh battery. I cannot find the 600 and was hoping that the 700 (being the same size) might do the job. It did not. Please advise of where I might be able to find the 600.

Arrived quickly, worked great. Don't need the device any longer as the TV went and we had to replace all the components. Ironic.

Worked Great, and holds charge 100% better then the old batter.

did it's job, so works great and can't find in stores.

The battery does not work.

it does not keep charge
