AA NiCad's: bad luck with Radio Shack "High-Capacity" batteries
I have since switched to NiMH batteries for many of my AA rechargeable
battery needs (walkie-talkies, cameras) but I still need NiCad's for devices that originally came with NiCad batteries and corresponding charging circuits; CD players that both my kids were given 12/25/03, a Garrity flashlight that came with four 600 mAh NiCad's, and my Norelco razor that I replace the batteries on with 600 mAh RS batteries that come with terminal strips. A couple years ago I bought a couple packs of AA "high-capacity" NiCad's from Radio Shack. I first bought some blue ones (cat. # 23-149A) rated 1000 mAh expecting much longer usage times. Instead I got performance much worse than the yellow Eveready's I had been using (capacity not stated on the battery) and than some yellow Sanyo's I had been using (600 mAh), and by "much worse" I mean probably less than 1/3 of the usage time (I've used them in walkie-talkies, and in AA flashlights). I didn't bitch to RS thinking maybe I ought to try other batteries, so I bought some silver ones (cat. # 23-325, 700 mAh looking for a capacity closer to that of the yellow ones that seemed to provide more use per chg. The silver ones also gave out after only very short usage times. The disk players my Kids got a little over a year ago seem to play for quite a few hours on a charge. Both Kids use them hours every day. My daughter's started refusing a charge recently, and apparently one of the original batteries must have been defective because it had what looked like corrosion on it. My son's are still going strong. You can't find NiCad's easily any more (I checked Wal-Mart, Kmart, Target, Staples, etc.) and reluctantly went to RS again. They only carry "high-cap." NiCad's now. I complained to the sales guy about how poorly the RS batteries performed that I had bought in the past. He assured me that I must have somehow abused the previous ones I had bought, and I finally (not having a quick alternative) bought another set of four blue ones (the only NiCad's they had). They look a little different now and have a yellow recycling seal, and they've left off the words "high-capacity", so I was hoping for better performance. But it turns out they're the same batteries; 1000 mAh cat. # 23-149A costing about $13 for 4. In neither CD player will they accept a charge that lasts more than a few minutes (even though my son's original JVC batteries still go for hours on a charge in either CD player after a year of heavy use). WHAT IS GOING ON??? To me this has been very frustrating and expensive too (the 12 batteries I can't use cost over 30 bucks). I must admit that the batteries I also got from RS (600 mAh yellow ones with terminal strips) have been working well. But their high-capacity NiCad's are horrible. I WILL return these last four (I bought them last week). I never use any of the Radio Shack batteries with a capacity over 600 mAh (the ones in my razor being the only RS rechargeable that I use). I still use my older yellow batteries and get much more use out of them (Kids' Walkies, flash lights). I don't know where to get batteries to get my daughter's CD player working (without an adapter). Should I order on-line and pay the cost of batteries plus S&H? What vendor? What type and capacity of battery? Can anyone come up with an explanation of my experiences with these "high capacity batteries"? By the way, I do try not to abuse the batteries; I charge them fully before first use, I try to deep-cycle them to prevent the memory effect, I don't drop them. In any case, the JVC's, and the yellow ones (the Eveready's and particularly the Sanyo's) work well under similar usage conditions. Any help on this would be much appreciated. Please E-mail a copy of your reply to as will so I don't miss it. Thanks much again. Ben |

Throw out the NiCds and use NiMH for everything. Take them out of the
appliance to charge in a fast smart charger. You'll get much longer run times, the only downside is that there's a faster self discharge rate with NiMH, so they need charging every month at least. Your bad RS NiCd batteries may have internal shorts caused by not being used for ages, how long were they on Radio Shack's shelves I wonder? "Ben" wrote in message oups.com...

Phil, dear -- neither my Canon PowerShot G2, nor my Dimage A2 use NiMH or NiCads. I do read this group and am aware of the content. But I also notice that there are a lot of folks knowledgeable about batteries. Sure I can use NiMH batteries (I have a Maha MHC401FS charger and over a dozen high-cap NiMH batteries) but 1. I am ****ed about the RS batteries and just wanted to know what was going on with them nad if others had had the same experiences and 2. It's much more convenient and easier on the CD player to leave the batteries in and let the player's charging circuit handle the charging, Thanks anyway Phil, Phil, Phil |

I didn't even try to use the old batteries in the CD players, only the
new ones. I too had assumed that the old ones were useless. It just seems so absurd that high-capacity batteries could truly be so bad. And it is so much easier to let the AC jack on the players provide the recharging power. And what about the razor (I feel self-conscious after Phil's post even asking about this). The set of 600 mAh batteries I soldered in are still providing a week's worth of shaving (they had initially provided over a month of shaves) after over three years of use (and they are RS batteries too). I am just vexed by this whole situation. RS has a pretty good reputation (or so I thought) when it comes to batteries, buy my personal experience with their high-capacity NiCads has made me steer clear of them when it comes to any batteries at all. Again, has anyone had similar experiences, and can anyone recommend a source for reliable NiCads. By the way Steve, the NiMH batteries I have have performed magnificently -- there's no question that NiMH is the way to go. Still, my Kids will destroy their players if they have to pull the batts out to charge them. Thanks Steve (and thanks all for putting up with my slightly "off-group" question. Ben |

and I want to add also that if the player is turned off and left
plugged in, that's when the charging circuit does it's job. Would that damage NiMH batteries is they were in the unit? When the batts go dead they'll use AC to listen to it; I'm sure they'd forget to unplug the unit half the time when they weren't using it. |

What you're buying now is old stock that's been lying around since who knows when. They do have a finite shelf life. Some here will surely take me to task for saying it, but the devices that have NiCd's and chargers now in your possession can almost certainly use NiMh's. Positively use them if they are of the slow charge 12 or 24 hour type. Give it a try with one of your older set of camera batteries. First give them a lecture. Stern fatherly lecture. That they never ever remove them themselves, never carry them loose. Never transfer them from one device to another. They are dangerous - I'm an old retired super cautious electrical guy, and I have the burn marks on my leg to prove it. Ken |

.... WHAT IS GOING ON??? ..... Ben I suspect that for one thing you are over reacting. Second you are forgetting that sh&* happens and there are things like bad runs that make it past quality control or old stock etc. It also happens that some batteries require a cycle or two before they come up to capacity. Take a deep breath. Consider the real meaning of life and consider moving on. Try NiMH's for the uses you are not using old technology for, charging them outside the device. They will work for many such devices. Also try running the old tech batteries through a few cycles to see if they improve. Life is short. Don't sweat the small stuff, this is really small stuff. -- Joseph Meehan 26 + 6 = 1 It's Irish Math |
