I recently bought 2 new 3.6v Ni-Mh batteries to go in my home cordless phone because the 10 year old batteries were failing. Then, a few days later we decided to cut off our landline service and simply use our cell phones for the limited home calls we make.
So now I have these 2 new batteries that won’t fit anything. I only paid $6/pair so not worth the postage to return. Is there any fun/useful purpose for them? They say 700mAh…. :~
I’ll try that since I can use AAA. Will they likely be unwrapped or otherwise need additional work? If so I am not set up for that and may not want to fool with it since I have some Turnigy AAA LSD heading my way
I busted one open and you were right - 3 AAAs! I had to trim off some spot-welded connections and they left tiny little nubs of sharp metal. I can probably get them off too with additional effort.
The wrapper is brittle and split on a couple. I peeled one all the way off. Is it important to rewrap them? Is the outer layer of it conductive? I wrapped the one with a layer of electrical tape but have not tried to charge or use them.
Yeah, I would make sure to wrap them as the body of it is negative. This means that if you place it in a light with a metal tube it will just stay on. (Nothing bad will happen, just the switch won't do anything)
Ok. I’ll make sure to wrap any where the existing wrapper comes off. I might even have some shrink wrap around.
Today all I did was bust open the very old (10+ years) original battery that came with the phone. We knew it was going bad as we did not have much talk time with the cordless phone off the cradle (hence the new ones I ordered). They discharged quickly in my T-6280 charger, then an hour later already seem charged. This is my first time charging AAA - should they charge that quickly?
I tried to do this. It wasn’t as easy as it sounds although eventually I got a small drop to stick. But the small drop then made the overall battery to long to fit into the holder. Any advice or visuals that could help?
When all I knew was Ni-MH I bought a bunch of these types from Ocean State Job Lot. They were 50 cents each and I got a lot of AAA and AA cells. All had tabs that were welded and all needed a dot of solder on the positive post. No problems, The ones that needed a wrapper I used heat shrink tubing, however sometimes the extra thickness was an issue.
Shucks, I was hoping for a thread about the lithium-ion little matchbox-size and smaller batteries for cameras and cell phones.
Such a handy pocketable size, I keep wondering why nobody’s making flashlights out of them. A row of LEDs along one side, say.
How did you apply the drop of solder? I found it very hard to transfer the size of a drop I wanted and it did not want to stick to the battery. Also, my salvaged batteries already seem to have a post on the end but it is wider than standard AAA battery posts so it doesn’t fit into the recessed hole my AAA devices have. Adding the drop of solder then makes the battery longer…too long…and now it won’t fit for that reason.
