Would you like to recognise the mystery as to how law enforcement and military personnel always have genuinely bright, yet compact flashlights? The answer is the way in which their light is powered. You are in all likelihood intimate with conventional alkaline powered flashlights and in all likelihood own a few, but you might not be as intimate with lithium flashlights. The following selective information is a brief introduction to CR123 lithium powered flashlights which describes some basic characteristics, benefits, and drawbacks. Although there are both incandescent and LED lithium flashlights available on the market, this info will focus mainly on incandescent or Xenon lithium flashlights rather than LED.

Unique Characteristics and Differences

Unlike the alkaline powered flashlights that you are in all likelihood used to which are powered by AA, AAA, C, or D alkaline batteries, the lithium flashlight is powered by a CR123 lithium battery. You may be intimate with this battery as it is many times employed to power cameras. Unlike traditionalisti alkaline batteries, which have a nominal voltage of 1.5v, a single CR123 furnishes up to 3.0v to the device it is applied in. The CR123 has a capacity (1500 mAh) in close relation to an AA and AAA battery (2700 mAh and 1200 mAh respectively).

The heart of the lithium flashlight, it is CR123 lithium battery, is the key element leading to the vantages and disfavor discussed below.

Advantages

First and foremost, due to the higher voltage of the lithium battery, a lithium flashlight have a tendancy to be much more magnificent than an alkaline equivalent. There are a heap of rather bright alkaline flashlights available on the market, but there are equivalent lithium flashlights available that are as bright or more glorious at a fraction of the size. For example, a 2-CR123 powered lithium flashlight is similar in size to a 2-AA powered alkaline flashlight, but is competent of fabricating over 4-5 times the light (the equivalent of a big and heavy 3-D cell flashlight). In fact, numerous 2-CR123 lithium flashlights, when outfitted with a high output Xenon bulb, may fabricate more light than a huge 6-D cell flashlight!

In addition to being more splendid for it is size, the lithium flashlight has one more big vantage over an alkaline light. If you have ever used an alkaline flashlight, you have in all probability noticed that it is brightest when the batteries are new and then not rather as bright as the batteries are used. With a lithium flashlight, this is not the case. Due to the lithium alchemy of the CR123 battery, a lithium flashlight have a tendancy to maintain it is luminance over the utile life of the battery until near depletion. It is nice to know that your flashlight is not going to become dimmer when you need it most.

Disadvantages

Unfortunately, all the great gains of lithium flashlights come with a few drawbacks. The introductory disfavor is battery life. A little lithium flashlight may be as bright as a huge multi-D cell flashlight, but it will not run as long. This is unquestionably where a compromise is made: battery life for physical size. The simple fact of the matter is that those D batteries have a much more outstanding capacity than the little CR123.

In addition to having scaled down runtime, CR123 batteries cost more to buy and replace than alkaline batteries. At this time, a single CR123 may cost up to $5 or more when purchased locally from a brick-and-mortar store (although they may many times be purchased online for $1-2 each).

Summary

In closing, the lithium flashlight is a outstanding option if you require a bright and compact flashlight for outdoors, camping, around the house, at work, or for each and everyday carry. If you don’t mind the few disadvantages, you will find that a CR123 powered lithium flashlight is a great option for your flashlight needs.

Low cost, but VERY low capacity
By NLee the Engineer
The latest family of Rayovac rechargeable NiMH batteries are all missing one thing: the capacity rating. Previously, you may see the charge capacity (such as ’2500mAh’) marked on each package and likewise on each cell. But newer Rayovac rechargeable NiMH cells are just grouped into three classes (‘Everyday-Use’, ‘High-Energy’ and ‘Hybrid’), with vague claims such as ‘Up to 275 photos’ printed on their packages.

Of course, those claims make very little sense to us, because Rayovac never tell us which camera was used, and under what test conditions were those photos taken.

After a lot of searching, I was capable to find the spec sheet for those cells from rayovacindustrial dot com:

- NM715-4OP ‘Everyday-Use’ AA, ‘Up to 275 photos’: capacity=1400mAh
- NM715-4B ‘High-Energy’ AA, ‘Up to 375 photos’: capacity=1900mAh
- LD715-4A ‘Hybrid’ AA, ‘Up to 400 photos’: capacity=2100mAh

The item offered here is the NM715-8OP (the ‘OP’ stands for ‘Opening Product’). It has the LOWEST capacity amoung all Rayovac NiMH batteries. I have tested some in my La Crosse BC-900 Battery Charger, and the intermediate capacity is genuinely higher than spec at 1500mAh. But this number is still very low by today’s frequent for NiMH AA cells. So even though the price looks attractive, this is just not a good value.

As of this writing, this 8-pack (NM715-8OP) is in truth priced higher than two 4-pack (NM715-4OP). Furthermore, the Rayovac 4.0 AA 4-PACK is available at even lower cost. Those are low-self-discharge cells with higher capacity of 2100mAh. So it is a no-brainer which package you will have to buy.

[Update on July 16, 2010]
I not long back came across a concealed gain of those Rayovac ‘Opening Product’ AA cells: they are precisely the same size as alkaline AA cells, while other NiMH cells with capacity 2000mAh or over are all more or less thicker. So for a heap of gimmicks with exceedingly tight battery compartment (such as the Rayovac Sportsman Xtreme 1W LED Flashlight), those are the only rechargeable cells I may use.

[Update Sep 4, 2010]
As if the offerings above is not mixing up enough, Rayovac has now discontinued the ‘Hybrid’ series, and substituted it with another two types:

- LD715-4OP ‘Pre-Charged’: capacity=1400mAh
- PL715-4 ‘Platinum Pre-Charged’: capacity=2100mAh

Got a good price, but charge capacity is VERY low
By R. Kohlhepp
I purchased these because of the price ($10.99 for and my good former experience with Rayovac. Right out of the charger, they will not power up my dSLR camera (Pentax K-x) and will only last for with regards to 20 shots on our old dSLR (Pentax k200d). They will last hardly a week in a bluetooth mouse, which other batteries last a couple of weeks easily. I am having a hard time finding a use for them now.

I have a LaCrosse Technology BC-9009 charger station that has a test mode. I tested these batteries and they came out to 1500mAh.

I still like Rayovac batteries, just not this model. I like their hybrid batteries and use them a lot.

low lower, not long lasting, 30% failure rate
By yosemite sam
i purchased four packages of these, based on pricing. they are not much better than the very cheap and low ranked tenergy batteries. out of 32 of the person cells in the four packages, 9 were deficient in their capacity to power up the malibu solar lights along my driveway. at primary they lasted regarding 4 hrs, then each night that time diminished to just being barley dim and lasting a half hour- at best.

there seems to be at work with their advertising, a distortion of what is what. they say they have x-amount of an increase in power, but they fail to compare it to anything that i could see. they completely fail to specify the mha rating. i knew they would not be in the 2000mah range, but i may only guess that they might be around 1000-1200mah’s. i tried these in my flip camera and they lasted far less than half the amount of time as did the sanyo enelope cells i own. of course there is a vast price divergence amongst those two.

so factoring in the near 30% failure rate i experienced, these then become pricey. add in the lower lasting power, the feeling of annoyance at being hindered or criticized of finding those that failed, having to modify out batteries more often…are these then worth what is being asked?

it seems to me that the old standard’s such as energizer, rayovac etc are not keeping up with the higher effigy that once was related with their brands. they to me now are by comparison been downgraded to the lower echelon.
