Go figure. The other thing, and something that makes me feel careless and stupid, there were some perfectly good rechargeable batteries in the box. Now, how the heck did that happen?
The difference was that this one is black and the other one was gray. Now here is the deal with this charger. It has four separate charging chambers that operate independently of each other. It also has a center 9V battery chamber but I have not been able to figure out whether that piggybacks upon one of the adjacent chambers or whether it operates separately.
There is a slider switch that allows you to select the type of batteries you are charging — they can not and should not be mixed and matched by type although, as I mentioned, various sizes of the same type work just fine.
There is no question that I experienced a bit of trepidation when I inserted the batteries into the charger for the first time. But there was no smoke and no explosion so I continued on.
In addition, the following lights will glow:. As I mentioned above, each of the four chambers operates independently so you could have a combination of these three options all going at once.
There is a chart in the manual that indicates that an AAA battery will take 2. In my experience, however, they charge to the fully-charged, green light stage a lot sooner than that. Now here is the thing. My experience is that if you leave the recharged batteries in the charger overnight — or say for about 10 or 12 hours — you will get a much stronger charge. I say this because I first tested some batteries right after the green light came on.
On my tester, they would register at about the half way mark in the fully-charged area. After doing this a few times, I realized that next on my bucket list was a tester that would give me the actual voltage of the re-charged battery. My brother and nephew — both electronics wizards — have one and tell me that is the only way to truly test the remaining juice left in a used battery.
There is one more rather important note that I want to make. I checked on my recharged batteries about two weeks after storing them in a box in my utility cupboard. Much to my surprise, there were some new leakers. Now whether these were overlooked initially had I wiped away the residue not realizing they were compromised or a byproduct of the charging process — I do not know. Even more curious, they were all the Costco Kirkland brand batteries.
The manual also indicates that alkaline batteries should not be recharged more than 30 times. For now, I will charge them once until I go through the pile and then start anew. But 30 times? I am going to play it safe and protect my devices by recharging no more than a dozen times if that.
Using the recharged batteries on low power devices such as mini LED flashlights and of course, my computer mouse, worked great. As a matter of fact, I can not tell the difference between the recharged Alkalines and standard rechargeables.
On the other hand, the Survival Husband uses wireless headphones to watch TV and the recharged alkalines only last abut 8 hours as opposed to the typical 15 to 20 hours with standard Ni-mh rechargeables. However, RAM and alkaline batteries are still available and are considered to be the most environmentally friendly. Here are the main pros and cons of alkaline and RAM batteries. NiMh Hybrid.

A good charger has only 65 mA or so going through the battery, but mine has so that's why I have to keep cycling the power to the battery. You'll need something to put your charging battery on. If, by chance, it should leak, you don't want to get battery acid on anything nice.
To connect the battery to the adapter, use alligator clip wires. Most transformers are "Plus-tip" meaning the inner circle the hole in the center of the plug is positive and the outer ring is negative I use a small length of wire with a bent end to stick into the center hole, that way I can clip wires to both connections on the transformer plug. Just wait. Yeah, that's right, stare at it. It's a battery, it's hooked up to some wires, and it's charging.
Yes, just what the label says NOT to do. Well you don't care, you're staring at it If you want, you can test the voltage going across it with an electrical tester, mine came out around 2V.
Yeah, just keep staring. Touch it every once in a while, make sure it doesn't get hot. After a while not more than a few minutes, to be safe take it out of the charger and test the voltage it puts out using the multimeter. If the voltage is high about 1. Repeat this step Once you've repeated step 4 a bunch of times, take your batteries and stuff them in something useful. I used my digital camera Canon PowerShot A Take a few pictures, try the zoom out.
Eventually it will probably stop working, probably before the low battery light comes on. Well, the batteries have high voltage but low charge. The camera usually measures voltage to determine when the battery is dead This can be fixed by repeating step 4 a ridiculous huge amount of times.
Charge up some Alkalines and reuse them. Think of all the landfills you're helping to keep battery-acid-free and all the money you save from the big companies. If nothing else, think of your accomplishment as an experiment and a proof of concept. Tip 12 months ago on Introduction. Do not used adapter directly connected to a battery. If adapter is rated 3.
So possibly it will charge your battery with 1A and that is bad. Use a serial resistor to limit current. To charge one battery from 3. Use a standard resistor 56 Ohm.
Charge 2 days with some pauses. That is most simple charger. You can add serial diode to protect reverse current. In that case, we have additional voltage drop on a diode of 0,7 V. So if you use a serial diode, apply resistor closest to 37 Ohm. Charging will last few days, but you will lower a risk to damage a battery. I have found recently this possibility to charge alkaline batteries. I use my lab current source adjusted to 40 mA.
Reply 5 weeks ago. Interestingly your method works! I've actually built a power supply to feed it the proper current and voltage but more the proper current. I fully charged 2 AA batteries in less that half an hour :P. I guess I'll keep it because I might need to charge some batteries really quickly, but I'm gonna go to radio shack to get some real parts to build it from and maybe even a generic PCB. My advice- be very careful recharging button cell batteries. And I mean exploded. The other two batteries got shot into the air.
