Charging Non Chargeable Batteries

[flydiver]

Li-ion rechargable are often referred to with a number like 18650 (length and diameter in mm). Most laptop batteries are made up of these. They are NOT lipos (lithium polymer) but their charge characteristics are almost identical. There are SEVERAL other lithium chemistry, which are not identical. I suggest you don't put any lithium in it until you spend some serious time on this site doing research.

I kinda think putting a primary (non-rechargeable) lithium in it would be a bad idea, maybe a very bad idea. But then I'm obviously not keen on recharging alkalines. Just because someone (wanting to make money) says it's a fine idea, doesn't make it so.

Chargers with multiple chemistry rely on an initial voltage assessment to determine how to charge. NiXX should never be above 1.5v. Li-on should never be below 3.0v, 2.0v at the absolute lowest. They are far enough apart the charger should be able to figure this out if the batteries are not severely depleted. If they are it should reject them. You need to be smart enough to tell the difference.

MOST CHARGING ERRORS ARE THE OPERATOR!

Re. temp - Take a look at the OUTPUT of the charger. If it's like mine its VERY VERY low and takes hours/days to charge even a small battery. It is s..l..o..w.
Not much gets hot at that output. You certainly DO NOT want to fast charge batteries not designed to be re-charged. That is simply looking for a fire, or worse.

Edit - looked at your link looking for specs. None of any use provided. That's not a good omen in my book.
I also noticed the weirdly skewed reviews. Pretty much people love it or hate it. Not much in the middle. Another bad omen. When I see a review profile like that I lose all interest.

I've given you enough to think about. I'm bowing out.

I was just amazed it stayed that cool..even at slow charge rate my rechargeable battery charger still gets pretty warm so do the batteries.I just assumed this one would get a little warm, especially after all those hours of charging.

No specs that is for sure. I just had to give it a try...so far so good. But Time will tell.

Ok , I have had this charger since Nov.2013 it is now March 2014 ( 4 months )

After testing and charging and installing in clocks, etc etc....I have learned that yes the alkaline battery does charge, however, none I have will last longer than 45 days before they start losing the charge.( in clocks-less in some other products )

Most alkaline batteries i use, are in wall clocks, game controllers ,camera's that sort of thing. Other than clocks,most things I remove the batteries after use, as alkaline batteries are known to leak at times.

So with that said, here is the issues, yes they charge and yes they work, they just do not hold that charge and the more you charge them the less they work, and the less they hold that charge. I charged many type alkaline batteries. AA, 9 volts, D, C batteries. I did not charge any NiMh or NiCd or lithium batteries at all.....

When i charged the batteries and stored them , some of them leaked after awhile. Especially the 9 volt ones ( for some odd reason)...so in trying this charger, yes as advertised it does charge alkaline batteries, but what they do not tell you is they will not hold the charge. Plus it will not charge just any alkaline battery.

If the battery is completely worn out it will not charge and if it is a cheap brand ( Dollar store off brand type ) they simply will not charge at all. So not just any alkaline will charge. I knew this was a long shot, but i had hopes at least i could get some extra time with batteries , instead of having to throw them out and buy new ones for such applications.

As Fly noted above, best to buy real good rechargeable batteries, you may pay a little more to start with, but in the long run they pay for themselves.

The only real good use for alkaline batteries is slow draw things like clocks,smoke detectors, and or other items you use and than remove after use like camera's or game controllers, etc etc.

This was not real expensive, but still, it was sort of a waste, but I had to try it. I thought maybe i would get, a few extra months 6-8 perhaps but only 45 days before they drop off and with each day they drop quicker....so it was not worth it as i had hoped. I have yet to get any more than those 45 days, and those were in clocks, less in flashlights ( D battery) and the 9 volts leaked after a little while. I have two that have not, but i am watching them to see what happens. So truly this product as stated by fly it is all hype.

Thought i would post my findings, really not worth the effort in the long run ( 4 months worth even )Lol
