magcharger @ 7.2 volts

[bser]

Hey fellas, I recently purchased a magcharger and replaced the stock bulb with a phillips 5761 keeping the stock battery pack. I'm impressed with the increased light but still want more. Because i use this light as an LEO and have chargers in the squads I drive I need the battery pack to charge with a stock charger. Is it possible to construct a 7.2 volt battery pack for the magcharger that will charge in the stock charger, and if so what is the best way to do it? If this has been covered please link me because i spent quite some time searching and located nothing. I've seen the question asked before but the answer usually indicated the charger would need to be modified for the battery pack to charge properly. This is not an option for me as the chargers in the squads belong to the department i work for.

Thanks for any help that can be provided.

Sorry, but I'm smiling at this approach: "I've asked the question before but I didn't like the answer everyone gave me, so I'm asking the question again in the hope someone will give me a different answer."

Now, I can give you a different answer if you like. I can tell you the standard charger will charge a modified pack with a higher voltage if that's what you want to hear, but will you trust the one answer from me that is different from the chorus?

I can answer that, yes it works perfectly. I have a Magcharger fitted up with a shortened, tribored body tube holding 6XA batteries. All stock stuff from Modamag. Smaller, lighter and more capacity than stock pack.

That's neat. How does the stock charger handle the higher voltage 7.2 V pack instead of the original equipment 6 V pack? Is it over specified, or just happy fortune that it works?

I do seem to remember someone reliable(Modamag,Fivemega?) saying the stock Magcharger charger will charge 4 to 6 cells properly.

Don't rely on that though,do a search for the thread,or maybe Fred(N162E) can point you to the proper source.

Thanks,

I use the AC charger. The wall wart is rated at 12 volts 300ma. No load voltage at the contacts is 19 volts. After 12-14 hours the batteries (Light) is just warm. I think we are simply dealing with fixed current. The A batteries (GP 2500s) are 2500 mah, charging at 300 ma is a little less than C/8. 12-14 hours seems about right.

Thanks Michael, "Fivemega" was the name I was looking for. Here's the link to the thread on my light http://www.cpfmarketplace.com/mp/showthread.php?t=121207

thanks for that link, dunno how i didn't come across it in searching, however its seems the shortened battery barrel is no longer available. that 6a battery pack would be exactly what i'm looking for, what would be the easiest way to modify this pack for use with a full length magcharger? If someone knows where i can get the shortened barrel still i would be all ears.

I spoke with fivemega and he advised he does have the shortened barrel and the "A" battery packs available but no "A" batteries left. Can someone tell me where i could purchase these at? Also would it be possible to use a 2D-> 6AA pack and a dummy 1/2 D cell to take up space? (the standard battery stick is 5 1/2 D cells)

Is there any reason this wouldn't charge properly in the stock charger?

The actual output voltage is higher than 6V. A higher pack will charge, just a little more slowly.

I tested up to about a 7 cell pack with it and it still charged at a decent rate.

You have some interesting possabilities here. 1, A 6AA pack and a spacer would work well but the light is still full length. 2, Get the shorter barrel and 6A adapter and fill it with AAs. The question here is will the AAs fit in the A holder the answer is no it dosen't work but, if you were to shim the batteries with duct tape or shrink wrap I'll bet it would work fine. The length of the cells is the same just a little more diameter. The Sanyo 2500 AAs will give you the same capacity. I am planning on putting Eneloops in mine, sometime. As your's is on a charger most of the time LSD cells are not important to you.

I am using the standard charger with 6XA cells 2500 mah. I can't imagine why using AA cells would present a problem.
