  14. To Charge or not to Charge

    From another discussion...

    The original rechargable battery was NICAD. The idea was a battery that was rechargable so that you didn't have to keep replacing your alkaline cells, those are your Energizers and Duracell's, for those who are not in the know. The problem was, a NICAD needed to be drained all the way before it was charged back up, and so many people didn't know about this. NICADS have a memory effect, if you drain them half way and then put them back on the charger, they remember that spot that they were in. Next thing you know your battery isn't lasting as long as it once did on a charge. And then eventually the battery dies for good, never to be reborn again.

    Then there are those who were knowledgable about the batteries, and they drained them down all the time. The batteries did last longer, but they still only lasted so many charges until the battery was shot for good. Because of the poor memory effect of these batteries, they were replaced by NMH. Nikel Metal Hydrate batteries were said to be of a major improvement, as they claimed that they no longer had the memory effect issue, and that they would last a lot longer. All they did is some battery restructuring, but they failed, IMO, to really solve the problem.

    The NMH batteries seemed like they were an improvement at first, but you still had to drain the batteries all the way before you could charge them up again. And just like with the NICADS, after so many charges, the batteries started to loose some of their oompth that they once had. Eventually, just like the NICAD, the NMH didn't want to take a charge anymore. Well, by this time they came out with, what I call, NMH battery regeneration technology. When you activated the regeneration mode on some smart chargers, the charger would drain the batteries all the way down, charge them all the way back up, then burn them all the way down again, and charge them up again once more.

    This process helped to restore the batteries ability to hold a charge. Unfortunately, what they never told us was, once a NMH battery gets torwards the end of its life, it doesn't matter if you try to regernate it or not, the battery has gone bad, it simply can not be manipulated, even by a smart charger. And then instead of that yellow light or steady red light, you get flashing red lights to indicate the battery has gone bad, please replace. So as you can see, NMH batteries were not much of an improvement over NICADS, and this is why for the most part, most companies have abandened the technology.

    Lithium batteries have actually gone through 3 generations, they've been around for the past 15 years. IMO, Lithium batteries have been, and are the true replacement to the older rechargable batteries. Lithiums batteries do not have a memory effect, as long as you keep the batteries charged. With these batteries, you do not burn them down all the way, and if you do, make sure you charge them immedietly. What a lithium battery has in common with a lead acid battery, such as a car battery, is that they both will go bad if left dead for too long. In a lead acid battery, the plates will sulfate, and once that happens its dead for life.

    Lithium batteries are very simular in that if kept dead for too long, you might as well throw them away. However, most people today are smart about their electronics and they always keep their lithium cell's charged. Lithium's don't like to be charged at 100% all the time either. When putting a lithium battery in storage, its always best to store them at 50% to 70% charged, this extends the life of the battery. And unlike the older battery types that would loose their charge after a month, lithium cell's will retain their charge 3 years into the future before you need to recharge them again.

    Lithiums are a much more reliable battery technology, they run longer, run cooler, require less time to charge, and can last many more charges over previous battery types. Originaly you had Lithium in the first generation, then the second generation brought us Lithium Ion, a marginable improvement. And I think we got now Lithium Hydroxide, or something of the like. Most electronic devies use lithium ion batteries. If you come across a company that is selling a piece of equipment using the old standard NMH, steer away.

    This is an attempt by a company trying to save money. They know the NMH batteries are no good, but they don't care, as long as they can squeese a little bit more money out of you, thats all they care about. If you are going to buy something with a rechargable battery setup, make sure its lithium ion! At this point in time, lithium battery technology is the best there is. I had a computer mouse, the Logitech MX1000 wireless lazer mouse. That thing used an internal built in lithium rechargable battery. It lasted me 7-years of heavy gaming use before its charge only lasted 1 day per charge. Thats how good lithium is.

    And there is the history of rechargable battery technology as best as I could remember it. Hope this helps

    What about M12 one-key? Will they have those tools? And if so, I guess now that I’ve invested so heavily in that platform, I’d have to start over again right… of course that’s only if the features are worth the investment for me. It just seems like they just came out with the new M12 fuel stuff, especially the circular saw, and now they’re saying thanks for buying these top of the line expensive tools thinking that you’re getting the best of the best, but guess what? , we knew this was coming and now you have to suck it up, and accept that your just released tools suck compared to these very soon to be released tools, THAT WE KNEW ABOUT ALL ALONG. I feel that they’re taking advantage of my addiction to buying the newest, “bestest”, tool on the market! BUT THEN AGAIN IT REALLY IS MY ISSUES THAT HAVE TO BE DEALT WITH. IT’S NOT THERE FAULT I’M SUCH A TOOL JUNKIE! LOL! But, I really love that my team really keeps blowing the rest AWAY. I mean really, Dewalt has blue tooth batteries. WOW! That was underwelming to begin with, but this makes them

    Banging the jobsite-drum leads me to believe that this'll be exclusive to M18 Fuels and targeting super-duper-hardcore-pro-contractors only.

    When I'm out and about and I see an electrician's rig or handyman or contractor I always try and see what the pro's are using when it comes too powertools...it amuses me.  Leave me alone.  lol

     

    A couple of weeks back, random electrician at a local business...he was rockin' an M28 Drill.

     

    HVAC guy installing a boiler at my house is rockin' an M18 Fuel Drill and a Makita Sawzall.
