I can't understand in this day and age how aaa lithium batteries such Energizer are so weak and not very strong. You would think they could develop a aaa lithium battery 3 times stronger.

The comment about a liquid battery. Liquid is heavy, 10+ pounds per gallon, that's why such a push for dry cells, plus the mess of liquid. When you put 10 gallons of gas in your car, you are also adding about 100 lbs. There are cell phones now with a type-c usb rapid charge system, 15 minutes can give up to 10 hours of use. When a car battery system can produce these type of results it will happen, but for now the logistics of an electrical vehicle is far off.

Is there some sort of cutoff switch in either the phone or the battery if the voltage is too high? Is there a safe way to lower the voltage, other than waiting for a very long time (It has been three weeks, and the 4.14 voltage has only dropped to 4.13 volts)?

Yes, quite serious. Fumble-fingered as I am, I have experienced the reduction of storage capacity, as in a quite noticeable reduction in usage time after charging subsequent to dropping the battery (usually though, after dropping more than once). As to "how" it could happen instead of simply failing outright, I cannot say for certain since I did not autopsy the device. I could offer some conjectures. Depending on the type of battery, perhaps the ion matrix was disturbed (as in li-film?) Or, as I suggested already, in the instance of multi-celled construction, with both serial and parallel units, if one of the units (or sub-units) became "displaced" the overall capacity would surely degrade, or even fail (of course), just like an analogous string of Christmas tree lights. Again, speculatively speaking--since I haven't opened up any dropped (degraded) units.

Just a note: most of the comments above about the life of the battery has to do with useage, heat vs cold, etc. However, in a battery that is made up of more than one cell (depending on physical configuration), dropping the battery >> can << affect alignment and thus charging amounts. An example of this occurs with some of the cheaper power supply backup units to provide power backups for your cell phone, music/video player, laptop 'puter, etc. If you open the case, you might well find a whole bunch of "AA" battery cells, which are themselves built up of several button cell batteries (i.e. watch batteries) stacked together. Obviously, dropping one of those units can quite easily result in a mechanical / physical displacement. This would of course affect the charge storage capacity.

I don't think it is worth the effort of switching to lithium for a golf cart: main advantage of lithium is low weight, which allows better performance in acceleration and on slopes; it also allows wider range. I don't think a golf cart actually needs such improvements. And a lithium battery costs 3 or 4 times a lead battery! But if you want to experiment, look for TMF lead batteries or TPPL lead batteries: the first should be cheap and lightweight, the second expensive but they will last longer. But I don't even know if they're actually already commercially available.

@Garrick: NiMH are older technology and heavier than lithium batteries. "lithium ion" is generic for several technologies, including Manganese Cobalt, which are present in some recent lithium batteries, but I don't know their performances. Sometimes by "lithium ion" are referred first-generation lithium batteries (lot of energy, poor safety, Lithium-Cobalt based). Manganese should allow better safety. @Sanjeev: At such low currents there's no much difference between lead and lithium; lithium becomes better at high discharge rates, for example 7 A from a 7 Ah battery (=1C rate). I don't know the DIScharge rate of your lantern, but 5W/12V means just 0,42 A REcharge for a 7 Ah battery, which means 0.06C. What you can do is replace the 12V/7Ah lead battery by a lithium battery with same capacity (7Ah) but 3 times lighter, or by a battery of same weight with 3 times the capacity. In both cases, battery will last longer than lead battery.

My previous comment: my laptop’s new Li-ion battery, with an impressive time period of more than two hours, just stopped working. I can not understand why… may be it was over-heated!

My new comment: I got another new battery and the same happened to it within 16 hours (It stopped working). Both times laptop was very hot (may be because I do not clean often??) and so was the battery. why was the battery so hot?? I’d like to think that system’s heat diffused into the battery!! 7% charge was remaining in battery for the 1st time and 34% remaining 2nd time. Both times laptop was working on battery power, and when the batteries stopped working it shut off like a AC computer whose power plug is pulled suddenly. Now both these batteries do not interact with the laptop. the message that appears on battery icon is “plugged in, charging” but no increase or decrease in the charge level. My laptop is HP Compaq 6910p. What is the real issue? Fault in laptop or just the heat?

There is no need to drain the battery, you can do charging as per the instruction given by the supplier. Need some instruments to do the optimization and It is dangerous without knowing the technique.

Just as a passing piece of information on the Li-ion aging, I have a Nokia 3510i which I've had since 2003. The battery is still the original, stays on most of the time and still has a standby time of about a week. As far as my feeble memory goes the battery still performs roughly as new! Being ignorant of battery properties I assumed that the longevity was a result of the Li-lion technology. The article would appear to suggest the opposite!

APC has the Symmetra system this unit uses “Lead acid” based batteries. This unit keeps Data Centers running during power outages in our client sites. Will Lithium be more effective than APC’s current batteries - perhaps price would be too high for the market? Any ideas? As the Global Warming effects start to appear in our state... keeping small Data Centers up and running for 24-hours and in some cases 48-hours electrical outages is critical - wee need better technology!

Hi Andy - NO you CANNOT charge a Li-ion battery in a NiCd charger. Each type requires a very specific charger, and it would be dangerous to attempt to do so.

Thank you for your reply BWMichael. But after further research, the answer is at least partially 'yes.' Perhaps my question should have been better stated as to 'physically' interchangeable. I understand that they require different chargers - and that is very important! I spoke with a DeWalt representative, who told me that the Li-ion and NiCd batteries were physically interchangeable on their cordless tools. And in fact, Porter-Cable makes a line of 'bare tools', which are sold without a battery - allowing the user to choose either NiCd or Li-ion. Thanks again for your input!

I am having problems with a 12 volt Li-ion drill & saw. Especially in colder weather the batteries just shut down - the battery overload protection just cuts in. I get this problem with the smaller 1,5 Ah batteries but not with the 3ah ones. Could the batteries of been damaged by being kept cold - they live in my van so could be -5 at night ?. Or could the batteries have developed a fault. Many tool shops are warning against Li-ion & are reporting lots of problems.

Ross: thats a big NO! The drill may work with a Li-ion battery if it fits, chances are it wont. But you cannot use a NiCd charger with a Li-ion battery. Lithium batteries are very sensitive and need specific chargers to control the amount of current etc. If your drill is NiCd i suggest you stick to NiCd or NiMh batteries. And if you really want a Li-ion battery for whateva reason, go buy a Li-ion drill.

I would like to know if more research is done into other tehnologies (non-lithium) because this element (Lithium) is in low quantities on Earth thus beeing unwise to over-develop something based on a rare material (just a very few countries have lithium reserves).

The C rating of a battery is its discharge rate (or it can also represent a charge rate). It is defined as the amount of current it can safely discharge over a period of time expressed in multiples of the batteries total rated capacity. A battery's C rating is equivalent to it's mah rating sustained for one hour. For example a 3000 mah battery being discharged at 1C, or 3000ma, will last one hour at that discharge rate, this equals 1C... At 0.5C (1500ma) it will last for 2 hours. That same battery being discharged at 2C (6000ma) would last 30 minutes, etc. The same principle applies to charge rates as well. Different technologies can handle different rates.

The search for a battery to power our electric cars should include an all liquid battery. Instead of having to charge the battery at home or at a charging station, I think a better idea would be to have a storage system where the liquid battery would be stored in the car untill the charge is spent and then like going to the gas station you would pump out the spent liiquid battery and put in a charged liquid battery. Instead of having to wait until the battery is charged(like the present situation) you would just wait until the battery(liquid) is exhanged. Another option would be to exchange a spent physical battery for unspent one. What do you think?
