Anybody ever see a D cell flashlight battery with a poor connection
inside? I had a flashlight that was giving me fits. The light would always fade out or quite at the most inopportune time. A shake or bang would sometimes get it working again. I cleaned battery connections and every other connection inside the flashlight. No help. Finally when I had the batteries out I happened to shake one and it sounded like liquid inside. There was a rattle in it! It was a duracell alkaline. The battery still had good voltage but an intermittent connection inside. New batteries solved the problem. Anyone else ever hear of a problem like that with D cells? 73 Gary K4FMX |

![]() I have seen this problem in quite a few flashlights and they don't seem to be brand specific either and it even includes a new maglight. It would always seem to show up when I was up in a very tight crawl space that took 20 minutes to get to :-). Maybe the D cells did get internal damage from being dropped because the symptoms were the same. Good thinking on your part, I would have never considered that. With kind regards.

I had a similar problem with a 5A slowblow fuse in a TCVR, on RX it was fine, but when I went to TX the fuse acted like a re-settable and went O/C. I spent hours looking in the TX strip for a problem ;=( |

Considering the large number of batteries I used the issue is a minor one in my instance. BTW, those Wallgreen batteries are a good deal, especially when they are on sale. RG |

It measured fine for voltage using a high impedance voltmeter, but wouldn't get the bulb much above a dull glow. There was no rattle to it, however, and I only solved the problem by throwing it away. - ----------------------------------------------- Jim Adney Madison, WI 53711 USA ----------------------------------------------- |

I have used that technique on quite a few circumstances. It works
pretty good. A good G-Force test against a cinder block wall never hurt anyone and is most just good entertainment Time is money! :-) ----------------------------------------------- |
