Go Green With NiMH Rechargeable Hybrid Batteries

The new NiMH rechargeable hybrid batteries have taken the market by storm. If your digicam or TV remote still runs on regular batteries, then you're definitely lagging behind in the technological world. These new Nickel-Metal Hydride are hybridone with complete charge.

They can save their charge for several months, which is not possible with the regular NiMH ones. This makes them ideal for low-drain appliances like remote controls and for high-drain gadgets like digital cameras.

It is safe to say that the creation of NiMH rechargeable with low self-discharge marks the commencement of a new era in battery-run devices. Although the battery capacity is not enormous, these rechargeable hybrid batteries have the power to retain their charge for quite a long time, extending to even a year. This quality makes them perfect for small gadgets as well as for backup power.

NiMH Rechargeable Versus Nicd And Li-Ion

NiMH (Nickel-Metal Hydride) cells are similar to Nickel-Cadmium (NiCd) cells. The NiMH battery has hydrogen-absorbing alloy for its negative electrode and not cadmium whereas NiCd cells have nickel oxyhydroxide for their positive electrodes.

NiMH one have 2-3 times more power than that of NiCd batteries with the same capacity. When you compare NiMH cells to Li-Ion cells, you will notice that both have similar volumetric energy density, but the self-discharge of NiMH batteries is higher.

What Is This Hybrid Battery?

In 2005, the market saw the launch of a new Nickel-Metal Hydride battery that featured amazingly low self-discharge. This extended the shelf life of the battery. Manufacturers of this battery used a new separator, which made it possible for the battery to save a whopping 70-85 per cent of its capacity even after a year. This happened when the battery was stored at 68 degrees Fahrenheit or 20 degrees Celsius.

Manufacturers introduced their new product in the market as "hybrid" or "pre-charged" or "ready-to-use" NiMH rechargeable battery packs. The design is similar to the regular NiMH batteries. They can even be charged with a standard NiMH charger. You can get these hybrid batteries from online stores as well as nearby retail stores.

Hybrid batteries are the latest fad, especially in the field of energy. The term has got a lot of attention lately because of endeavors to reduce carbon footprints, use energy efficient appliances and save the earth.

Hybrid means anything that is between traditional and the future technology. Hybrid NiMH rechargeable cells mark one step towards future technology, yet exhibit a hint of conventional battery design. This makes the battery green or environment friendly.

There is no need to worry about the cost, as these NiMH batteries are inexpensive. Besides, the performance and voltage are similar to conventional alkaline batteries of the same size. Alkaline batteries are usually 1.5 volts while NiMH batteries are 1.2 volts. During discharge, the alkaline voltage drops in due course and becomes lower than that of NiMH voltage. NiMH rechargeable hybrid batteries are capable of maintaining their voltage. This is one of the qualities that gives these hybrid cells an edge over the traditional ones.

Rechargeable Triple-A Batteries - Don't Leave Home Without Them

If you are tired of pressing the button on your camera and seeing the dead battery indicator, you need to get a better set of rechargeable triple-A batteries. And when it comes to rechargeable batteries, there is one and only one industry leader that is by far and away the most reliable and most popular batteries around.

Without a doubt, the Sanyo Eneloop triple-A NiMH Pre-Charged Rechargeable Batteries are the most popular rechargeable triple-A batteries anywhere online. They have more than 900 customer reviews! That's right - more than 900. And the Sanyo Eneloop triple-A batteries proudly walk away with a 4.5 star rating.

The reason that Eneloop batteries are so popular is that they seem to last forever because they have a very low self-discharge. Self-discharge means that a battery loses its power when it was not in use, even if it was continuously charging. That is why most rechargeable batteries were not sold fully charged. By the time you bought them and tried to use them, their power would already be gone.

This is one of the reasons why normal rechargeable triple-A batteries got a bad name. They had to be continuously recharged, and even then you weren't guaranteed they would work very long because they discharged so quickly. On top of that, if you charged the batteries without them being completely dead, you drained its ability to recharge.

And this is why Eneloop products are so popular now. Eneloop solved all of these problems by created a low self-discharge battery. This means that you can buy fully powered batteries and use them immediately. They are perfect for electronics including cameras, remote controls, flashlights, and so much more. They can keep up to 85% of their charging ability after one year. Compare this to more traditional rechargeable products that are completely drained and useless by then.

So how long exactly can Sanyo Eneloop rechargeable batteries last? They can be recharged up to 1,000 times without losing their charging capabilities. You would be lucky to get 10% of that out of normal batteries.

Oh, and one more great thing about Eneloop - they are not that expensive. You can get a 4-pack of rechargeable triple-A batteries for $10 if you know where to look (hint: start at Amazon).

So the second most popular set of rechargeable triple-A batteries is Sony NiHM. These also come in packs of four which will run around $10. Now you won't see the rave reviews that you see on the Eneloops' above, but these Sony products still are pretty good. They stay charged longer than most, but they can take a little longer to recharge.

People talk about getting 20 - 40 hours out of them before they need to be powered back up, but the amount of time you get will be completely dependent on what you are using them for.

If you are looking for rechargeable triple-A batteries along with the charger, here is the Duracell Mobile Charger that can charge double-A or triple-A.

Duracell Pre Charged Rechargeable Nimh Batteries Combo Review

Duracell have been manufacturing high quality batteries since the 1920's and have developed a reputation as the world's leading battery manufacturer.

The Duracell Pre Charged Rechargeable Nimh Batteries Combo is a compact battery charger, which is ideal for high drain appliances. The specific model of this charger is the Duracell CEF14NC. Duracell have made a couple of enhancements over their previous value charger; these include a universal voltage input and the ability to charge up to 4 triple A cells.

Features of the Duracell Pre Charged Rechargeable Nimh Batteries Combo

Charges up to 4 triple A cells
Accepts a universal AC input of 100-240v
Duracell Pre-Charged batteries can retain power for up to 1 year when not in use
Supplied with 8 Pre-Charged batteries (4 AA and 4 triple A batteries)
Ideal for use with high drain appliances

Charging

A plus point is that you can charge up to 4 triple A cells at once, unlike with many other chargers which can only charge 2 triple A cells at a time.

Batteries can only be charged in pairs or sets of fours, which is rather disappointing because you can't charge only 1 or 3 batteries if you have an appliance which requires batteries in odd numbers.

Another disadvantage is that the charger only stops charging when the combined voltage of the 2 batteries is sufficient enough. This means that if you are charging 1 empty battery with one which is either full or almost full then one of the cells will be overcharged which is detriment to the length of the batteries life.

Charging Times

The charging times are reasonable. It takes about 6 hours to charge 2 AA batteries, which are empty. The charging current differs depending on the type of the battery which is being charged. AA cells are charged at 360mA and triple A cells are charged at 180mA.

Universal AC input

Accepting a universal voltage input of 110-220 volts, this is ideal for use as a travel charger. There are no adapters or cords, the charger plugs straight into the wall so packing the charger away for storage is very easy.

Supplied with 8 Pre-Charged batteries

Duracell have included 8 pre-charged batteries in the combo package. The battery types are 4 AA and 4 triple A. As they are pre-charged, you have the convenience of being able to use them right out of the package.

The supplied batteries have a very good lifespan, even with high drain appliances you get about 10 hours usage from the triple A cells.

Final Thoughts

Overall, the Duracell Pre Charged Rechargeable Nimh Batteries Combo is a good deal. The charger is portable, well built and comes supplied with 8 quality long life batteries.

On the downside, the fact that it only charges batteries in either pairs or fours could be off putting if you have appliances which require an odd numbers of cells. Also, there is a possibility of batteries becoming overcharged unless you only charge cells together which have similar amounts of power in them.

If most of your appliances accept cells in pairs, then this is a good buy, but if you want more advanced features such as individual cell monitoring to charge batteries singularly or in odd numbers then I recommend a charger such as the Sony Cycle Energy BCG34HRE4KN.
