Tactical Light batteries

Picked up a Tatical Light curious is it best to store the batteries (CR 123A)installed in the unit or store the batteries individually outside the unit . I have visions of leaky batteries from early discharge.

If they are lithium it should be fine to leave them in the flashlight.

Hi AA3jy,

Being lithium, you can leave them in. After all, when you need a flashlight...

We have several such flashlights on-board (one at each fire extinguisher for starters...) If your light holds 2 CR123A batteries, you might consider buying some rechargeable 18650 batteries (one of these is the size of 2 CR123 batteries...) and can easily be charged on your 12VDC house batteries [with the right charger... we use chargers that are 12VDC or 115VAC...]

The 18650 batteries have become a commodity item since e-cigarettes gained popularity, and are therefore relatively cheap.

e.g., Here is a quick look-up on Amazon.

In case this is of interest.

Cheers!

Bill

Re: Tactical Light batteries

Any flashlight is better to have the batteries out of the flashlight, but it is not very useful in an emergency now is it? Look to Amazon for CR 123 batteries, but be cautious looking at reviews and make sure it is a well rated seller. Buying them locally is close to extortion. I have found even locally sometimes the multi pack is the same price or even less than the single pack, strange as that is. I try to use flashlights with AA as they seem to last the longest, then AAA. 18650 are really nice, but there is a HUGE difference in quality of the batteries and there are lots out there that are sketchy. Often if you get an inexpensive light with one they are pretty lame. I have heard the same about the rechargeable CR123s, quite variable.

Hi Paul,

You are absolutely right about the range of quality with rechargeable batteries. It is always best to research...

We have found name brands seem to be consistently best.

e.g., We use Sanyo Eneloop AA and AAA [lowest self-discharge rate...] , and this Panasonic 18650 [protected version...]

There are no doubt other high quality choices out there as well. These are just what I have had successful, first-hand experience with. [And continue to receive high rankings from other reviewers...]

Cheers!

Bill

Are you active on the candlelight forums? Tons of info there, but they do tend to get a bit out of hand. The new LED flashlights are amazing. I have a cheap one from some Chinese web site that is amazing under $10 and it is as bright or brighter than a wired 50 watt spotlight! All on three AAA batteries (or an 18650). Those Panasonic look good since they are protected. That is my biggest fear is that I will over charge/over drain it and start a fire. Especially scary are those cheap chargers!

Hi Paul,

I am familiar with Candle Power Forums; they often come up when I'm researching, but I'm not active there. I agree about it being a great resource [assuming that is the one you were referring to...]

Yes, the state of the LED technology and the ever decreasing pricing takes away those arguments against having several of these super bright lights onboard.

You are right: we need to be careful with battery and charger selection. We found a good, computer controlled unit that accepts 12VDC and 115VAC as inputs, and has individual digital readouts for each of the 2 battery bays. Over the last 2 years it has performed very well. [I'm off the boat right now or I would share the specific model... However, in 2 years there are probably even better choices available now...]

Here's to our ongoing illumination...

Cheers!

Bill

Re: Tactical Light batteries

If you want or need a flashlight that you can just pick up and USE, then you have no choice, you keep batteries in it. I don't think all the CR123A's are lithium though (knock wood) I haven't had any leak. Yet.

You may also find that it is a good idea to put some silicone di-electric grease on the contacts in both ends of the flashlight. And in between the batteries. Makes the batteries a little messy to handle, but the grease tends to keep any leakage on the battery, under the grease, so the flashlight isn't harmed if they do leak.

I've also gotten in the habit of printing a label, i.e. "2016 expires 2025" to match the battery installation and "use by" dates, on lots of things. (Not that Duracell and others haven't leaked well before their dates!) It saves the annual "do I need to change these?" question.

Do you mean just smear a thin film on the contacts, or to 'fill' the space between the batteries, and even the flashlight itself? I can see how the latter might confine leakage but it would be incredibly messy

Re: Tactical Light batteries

I don't try to fill anything, except the springs that usually is at the negative end of the battery. I try to put enough grease in that so that a leak can't form a blob inside the spring, since those are hard to really clean out again.

But I'm not parsimonious about "a smear" either. I try to use as little as I can, so as not to make a mess, but enough to ensure that anything which might be damaged by a leak, is protected from it.

Kinda like, how much butter do you put on your toast, anyway?(G)
