I have battery testers that say good bad or ugly but I wanted a holder to be able to test with my digital multimeter because I recharge batteries and want to get the ultimate charge into them. My charger is not automatic shut off. So I went and bought some alkaline batteries for my camera because the rechargeables lose their charge quickly in my camera. And so what I did is kept the package the batteries come in. I burned a small hole in each end of the plastic wrapping that the batteries came in and now that's my holder. So much easier to test now. A picture is worth a thousand words.

Good idea ! I test my batteries on my computer table, and my desktop ledger that I write everything I want to remember in, holds them pretty good for the times I test them. |

THat's pretty clever, campy. Testing batteries while they are rolling around the glass desktop is a pain in the ass. Roughly in this vein, I have taken to using AA NiMH rechargeables wherever possible. Main TV remote control is funny. It is set up for 2-AA 1.5V alkalines and shows a "replace batteries" presumably at some voltage or amperage drop. Funny though with 2 -AA 1.2 volt rechargeable NiMH's I get no such warning and I judge them dead when I push the ON-OFF 15 times til I get a response. It takes the full 5 hour charge and I am good to go. So I know they really are dead. (I get several months between recharges and I am a TV addict. Any guesses why no warning with the rechargeables?

I really don't know why the remote works better with rechargeables. Maybe because Remotes are low draw. And alkalines allow more drain? Then again capacitors might come in to play? You might get a better light on the remote but a weaker light is just as good to power the infra red beam. The same thing happens with my old Fuji camera. Alkalines deplete themselves faster than rechargeables. The manual recommends rechargeables. The problem with rechargeables is self discharge. I'm now working on simple holder. Two pieces of wood. Held together and drilled to accomoddate two battery sizes. Then a hinge on one end. Flip it open. Pop the batteries in, flip it closed and they are held for testing. Wondering why it's not on the market. Forgot to add. The manual says not to mix batteries. They never say why. It's like me baking a pie. The instructions say to dot the filling with butter before adding the top crust and I always ask myself. Why? What's going to happen if I dont.? Edited by campy, Dec 11 2016, 10:53 AM.

I recovered the battery case from an old solar light and use it to hold the battery's for testing. When I used to build electronic projects, I used to buy battery cases at Radio Shack. A battery case would likely work for testing also. Of course, THE SOURCE store has now replaced RADIO SHACK. |

I have encountered instances where a remote won't work with rechargeable batterys. A fully charged rechargeable battery is 1.2 volts. Disposable batterys are 1.5 volts. My satellite remote uses four cells, so the over all voltage is .3X4=1.2 volts short. This would be the equivalent of trying to run on only three standard cells. |

Yep and they don't stock the neat stuff anymore. I was looking for a female 3.5mm plug that I could wire in to an RCA input. They didn't have a clue. |

I have mastered the art of holding a battery and a probe in one hand. But I like the idea making a holder or using a surplus battery holder that is hooked up to a voltmeter permanently. I have some cheapo $1 meters; must check what operating voltage they need. http://www.ebay.ca/itm/401103240801?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT Anyone seen the Chinese 3.7 volt AA size cells? I ordered a set with charger when I saw the little flashlights I was buying could use them. I'm hoping for much improved brightness. http://www.ebay.ca/itm/401103240801?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT These little focusable flashlights are very good with a single AA. It says they use the 14500 cell as well. http://www.ebay.ca/itm/252610041506?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT How come AAA rechargeables have disappeared from dollar stores? I ordered some from eBay. Edited by Delphi51, Dec 13 2016, 05:17 AM.

I will be checking today at Dollarama. All dollar stores don't stock the same stuff I found out. Maybe the reason is the price of their super heavy duty AA's. $1.25 for four. I bought the package and opened it carefully so I could make a new updated version for charging my AAA cells. The picture I showed before was for AA cells. With the new version I can test 4 cells at a time. And if they are all good? I just leave them in the package. If not I take it out and charge it up. |

I did not mean to imply that rechargeables work BETTER in a TV's remote control just that they gove no visible signal of being dead and I have to guess. The AA's showed the dead battery icon on the set. I find NiMH batteries barely have any drain during disuse. They last FOREVER in my camera even with no use for months. |

All remotes are different. With mine when the battieres are dying but not dead, when I push the channel button the t.v. light blinks 3 times. Modern technology. A guy holding 4 remotes in his hand not including the garage door opener and the car door. That's probably because your camera doesn't drain because of the peripherals holding memory are better designed. With my old camera of course the time and date are kept up to date even when the camera isn't being used. So naturally there is a bit of drain. But my NIMH are from the dollar store and they are only 800 Mah. I only use the camera on special occasions because the cell phone camera works better. |

Delphi. I checked at the dollar store today. No AAA rechargeables. I don't know why.

I just got this lot of a dozen AAA and a dozen AA for $13. http://www.ebay.ca/itm/351846930509?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT They aren't Kodak by any means but the capacity is better than typical dollar store fare. I may never buy them from dollar stores again. The USB charger might even be useful when camping - somebody gave me a solar powered USB power Jack. We use AAA reading lights. They require 3 cells because white LEDs need 3 volts. The flashlights I linked a couple posts back work with 1 AA by means of a remarkably efficient voltage tripler circuit.

I never try EBay and I should. My electronic oven control calfed yesterday and I don't think the part is available anymore. I'm not going to bother with a service call. They want $73 just to look at it. I'll find out if the part is available first and possibly get them to install it and save the service call. I don't bake much now anyway so will just buy a toaster oven for muffins and stuff with the $73. |

I only go for bargains on eBay so a disappointment is no big deal. The quality varies from excellent to junk. I did find a perfect match for my friend's barbecue igniter for half the price his normal supplier charges (he is a retired appliance repairman). Give it a try - it's fun! First sign up for a PayPal.ca account. Only use eBay.ca so all prices appear in our dollars as well as US. Be aware of shipping charges. Things from China are usually free shipping and take a month to come. Edited by Delphi51, Dec 14 2016, 01:38 PM.
