remember one thing about batteries - remember this. There is no perfect battery. However, there are some general rules that apply to all rechargeable batteries. In normal use, a Nickel Cadmium (NiCd) battery will last LONGER between replacements than either a Nickel Metal-Hydride (NiMH) or a Lithium-Ion (LiIon). In some cases, the use of non-rechargeable alkaline batteries can actually provide a lower operating cost than rechargeable batteries!
Case in point - the popular Motorola Minitor IV paging receiver. Everyone (or at least almost everyone) has assumed that the only way to purchase this receiver is with the OPTIONAL rechargeable AAA NiCd batteries and desk charger. Let's look at this another way. Assuming a price of $319 for a standard pager and charger versus a pager with no charger and 48 alkaline batteries - which is the best value?
Would you believe the pager WITHOUT the rechargeable batteries (The Minitor IV uses two AAA batteries) is the better value? It is - here's why! The price of a good quality alkaline battery will range in cost from $.30 to $.35 cents depending on quantity. Assuming a pair of batteries providing an operating life of one month for a typical user means an annual operating cost of $8.40 (12 x 2 x $.35). Our five year operating cost will be $42.00 less the cost of the 48 batteries included with the price of our pager. On that basis, our cost for the first 24 months is ZERO (2 batteries per month times 24 months = 48 batteries). Your cost for the remaining 36 months of operation would be $25.20 (2 x $.35 x 36).
NiCd batteries generally require replacement on an annual basis. The typical selling price for a pair of NiCd rechargeable batteries is $6.00. The five year cost for NiCd batteries is $30.00. Therefore your true operating cost for using non-rechargeable alkaline batteries over a five year period is actually $4.80 LESS than using rechargeable batteries. And that's only PART of the real benefits. With alkaline batteries, you don't have to remember to put your pager in a charger every night. If the batteries get weak, you can grab a couple out of your box of 48 and you'll never miss a page. You have less to remember, greater reliability, more flexibility, and you save money BY USING ALKALINES!
So what about NiMH batteries? Aren't they better than NiCds? Not in cold weather. NiMH batteries don't like the cold. They do provide more capacity which means they will operate longer between charges. A typical AAA NiMH will have a battery capacity of around 1000 mAh. A NiMH can have a capacity of 2000 mAh. So that means it can operate twice as long between charges which is good. What is NOT so good is that it also takes twice as long to charge (20 hours versus 10 hours for the NiCd). In this case, the NiCd would be the best choice if you prefer to use a rechargeable battery.
Did we mention that a NiCd typically has half again the operating life of either a NiMH or LiIon an generally costs LESS?
So what is the benefit of the LiIon battery? In a word - CAPACITY! You can have more storage capacity and less weight with a LiIon. That is why they are so popular with cell phone users. LiIon batteries are also environmentally clean which means that no special disposal is required (as is the case with NiCd and NiMH batteries).
As you can see, there is no perfect battery for every use, but there is one thing you can do to make sure you keep your battery cost in line. Buy only top quality batteries. In the long run, you will save money!
