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. The recharged 9V battery worked especially well on my little Blocklite flashlight.
When I turn the switch to 2 LED mod, it is as bright as ever. Clearly, for now, at least, it appears that the recharged alkaline batteries are best suited for low-drain devices. I purchased these inexpensive storage cases for my recharged batteries. They are really quite handy and I like that the six individual cases interlock and connect together to make a larger case. The rest of my spares are in the plastic pencil case you see pictured above.
Would I trust these recycled batteries in a survival situation — sure, if that is all I had, But of course, that is not the case. I still have a large supply of brand new alkaline batteries in all sizes plus a good supply of standard rechargeables you know how I love those Eneloop rechargeables.
But as spare batteries to use day to day, heck, these are great. As my tests have proven, a recharged alkaline battery can keep a small LED flashlight going to over a week and a computer mouse for much longer than that. As a matter of fact, you might say I have become obsessed with using these recharged alkaline batteries. But that, of course, is a story for another time.

I do hope you will consider the battery tester — it will definitely pay for itself by preventing you from recycling perfectly usable alkaline batteries. Hybrid batteries are Nimh batteries with some changes in their construction resulting in a slightly lower capacity than the standard NiMh, but adding the benefit of a slower self-discharge.
With the decreased benefits, most manufacturers have discontinued their RAM batteries and chargers. 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. Learn More. You may order via phone, our website, fax, and email. With that sort of current, you shouldn't leave the batteries connected very long at a time.
The voltage on the batteries will go up quickly, but the actual amount of charge will not. Because of this, you have to disconnect the batteries frequently to let them "cool down" though they usually don't even get warm, the voltage will quickly drop down to around 1. After they have leveled off usually around 1.
Repeat this a bunch of times to get the charge up. I've just started experimenting, but I was able to get enough charge in two completely dead batteries to start up my power-hungry Canon digital camera and take a few pictures with screen and flash and turn it off without it dying on me died the next time I turned it on.
You'll want to find an adapter plug from something you don't care much about. Backwards powering batteries can lead to current backflow battery power going through adapter which can ruin some adapters, though usually at 1. I found a Nokia phone charger works good. You also don't want really high amperage. Since high current charging leads to leaking batteries, try to find as low current plug as possible look at the mA rating.
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.
It can either be rechargeable or disposable and generally has 1. It is also available in a wide range of sizes. You can see these alkaline batteries being frequently used in daily electronics.
However, before using this type of battery, it is necessary to get to know more about its pros and cons:. You can also expect alkaline batteries to perfectly suit applications with normally low current used. These applications include devices that operate without the need for a huge amount of power as well as those gadgets used only periodically, such as radios and remote controls. You do not also need to worry about it going bad due to age as there is a low chance that it will happen.
Aside from the shelf life, an alkaline battery also boasts of its longer lifespan in comparison to its counterparts so there is no need to replace it too often. However, it also carries a few flaws, like:. Despite that, alkaline batteries still continue to gain traction nowadays. Charging or recharging alkaline batteries is not highly recommended , although that is possible with the help of a special alkaline charger , which you can use to the rechargeable alkaline.
There are several reasons why recharging the battery is not recommended. One of these is that charged ones can supply only a few recharge cycles. What you get is a dozen of recharge cycles , sometimes even less. This is not the same with a real rechargeable, such as NiMH , since you can also recharge it for hundreds or thousands of times. Alkaline batteries also tend to lose their capacity per charge cycle. This means that each time you recharge the battery, its run time will also go lower.
The rechargeable variety of alkaline batteries also usually features a smaller capacity compared to the real ones as well as NiMH rechargeable batteries. Recharging it will also increase its likelihood of leaking. The good news is that despite the fact that charging alkaline batteries is not recommended, there are still special chargers that you can use to do so.
Note that it is necessary to invest in a high-quality special charger specifically designed to charge alkaline batteries if you insist to do it. You need a charger, which is specifically designed to deal with and handle alkaline batteries. It also has built-in negative delta V cut-off function and short-circuits protection.
