After many questions about how many rechargeable batteries can you put into a light?
It is not on how many re chargeable batteries but on how much voltage.
An example is the Olight M30, I can use either 3 or 4 CR123 batteries. Most people ask if you can use 4 re chargeable batteries in the M30? The answer is only if the Max. voltage is below 12 Volts DC.
As most all of the re chargeable CR123 batteries are 3.7 volts each, they will not work. 3.7 x 4= 14.8 volts or 2.8 volts too many.
This will overload the circuits and cause them to heat up or just plain burn up.
You can use (2) 18650 4.7 volt re chargeable batteries in the longer configuration with out any issues.
Also there are questions of what size batteries will fit into each type of light?
The M Series Use the 18650 or the CR123 batteries. Tbe magazine is a little larger to accomodate the thicker 18650 batteries.
The T series will only fit the CR123 batteries in the magazine.
There several other more exotic size batteries that I will call the exception to this rule but they are harder to come by and usually more costly.
Thank you

litium ion battery and tactical lights
Well here we go.
Most people have heard the wives tales about batteries.
1) You have to run the battery DEAD because it has MEMORY.
2) Leave it on the charger to keep it ready to use.
3) Re chargeable batteries don't last as long as single use batteries.
and many more.
Well these are the ones we will talk about today.
First. If you run your lithium battery dead there is a chance the two poles will swap creating a short when used with other batteries and cutting your run time and even make it possible to have a explosion. If you put a weak battery or a different kind of battery in a device there is a chance (pretty big) that the weak battery will heat up and cause the other batteries to either shut down or build up pressure and burst.
So when you put batteries in a device, make sure that they are well matched. If you are not sure, fully charge them and start over. If you are using single use batteries, you will need to use a multimeter and check the voltage.
Keep batteries as close as possible in voltage. I put them in baggies with a voltage to the .05volt marked on the outside so that I have matched sets. At Shows or demos I take the batteries out and put them aside for later.
Next if you leave the battery on the charger there is a chance that it will over charge and heat up. Heat is one of the hardest things on the batteries. If the battery gets too hot it can loose it's ability to re charge. At the least it will shorten the life span of the battery. They say that you should let the battery cool down before charging and let it cool off before re installing it in the device. This will produce a far better run time.
Lastly, if you get the re chargeable battery with a "mah" rating as close to the single use battery as possible. MAH stands for Milli Amp Hour rating. This tells you how much energy the battery is able to store. If you get a rechargeable with a mah rating of 750mah and the single use battery is 1400 mah then the rechargeable will only last aprox. 1/2 as long as the single use. If you get a rechargeable with an 1800 mah rating then you should get a longer run time out of the rechargeable . The main reason that most people get the shorter run time is the cost of a higher quality/higher run time battery can be quite different from the lower mah battery.
Also the quality of batteries is varies wildly. I have bee through a dozen different types of batteries trying to get good ones for my flashlights. Pricing can be from $3.00 to $25.00 for a CR123 rechargeable. Paying more does not mean that it is the best battery. some of the more reasonable batteries can be very dependable and have a good run time. The next issue is supply, Lithium ion batteries are prone to explode and most airlines have restrictions on transport. Some will not allow it at all.
Well I hope this helps, If you have any questions please let me know.
Thank you.

Olight Superior Tactical Lighting New Product update
Hello,
I am new to this but I thought that is may be intersting to know some of the new products that are in design and may be coming out soon.
The latest offering from Olight is the SR90 Intimidator.
I have had it for a while and found that is a well made and impressively bright light.
In showing it to some of my friends locally we have put it up against their spotlight on their cruisers. The SR90 out shines most of them and it is mobile with a 90 minute run time on the included, re chargeable battery magazine.
All of the lights are very water resistant and shock resistant. I can not believe the amount of light it gives off.
I had the opportunity to test it in my church main sancturary. I was blown away with the light.
I shone it tward the ceiling and it lit the entire room. The M30 and M20 did well but the SR90 did not matter which direction that it was pointed, it just lit up everything.
I also took it out to my very generous friends farm and tried it out for distance, and WOW!
I could see things clearly at about 800 yards. Also this light STROBES as well. I have thought that this would make an awesome boat light. If you get out and have your battery die you don't have to worry, the light is totally self contained. If you dropped in the water you would not have to worry.
Ok on to the new lights coming out.
There is a new version of the SR90 that will be coming out soon. It will be rechargeable and have about 1600 lumens, I don't know what the name of it will be. It should be in production early in May.
I can't wait to see it in person. I have a spy photo of it on the front page of my website. It is sitting beside the M30 and SR90 in the under water picture. I will let you know more about this when I get more informantion or I get my first light. I have already put some on order.
On the topic of new things. I am testing my next re chargeable batteries. I have been through so many brands that it is no longer funny. I am testing the Tenergy 900 mah CR123 now and it is not doing well in the M30 I am going to try several othere lights to see if it was a fluke.
I am only getting about 40 minutes instead of the 90 to 100 minutes that I get using the throw away batteries.
If there is anyone out there that has any good re chargeable batteries that they like, Please forward that information on to me and I will get some to start testing.
Well this is my first Blog
