Help looking for a battery

[50 Freak]

I bought a Brinkmann Maxfire Dual Xenon Spotlight http://www.brinkmann.net/Shop/Detail.aspx?category=Flashlights+%26+Spotlights&subcategory=Flashlights&sku=800-2200-0&id=139

Well the stupid battery is dead, won't hold a charge as I can charge it all night and it will give me about 5 minutes of light.

I called Brinkmann for a replacement battery and they don't carry it. Told me to check with RadioShack.:thumbsdow

I've tried looking on the web using the model number and product number with no luck.

Can anyone lead me to an alternative battery or source for this stupid battery.

On the battery it shows "PowerOne" and KT625 and on top of the battery I presume this is the product number as it has 04H28

Thanks people.

While Brinkmann lists it as a NiCD battery, I suspect that the battery in that light might actually be a Sealed Lead Acid battery, as is commonly used in those portable spotlights with the self-contained batteries.

If you've already removed the battery from the light, can you confirm that it is SLA and not NiCD. If it is a SLA battery, it is usually a standardized size and you should be able to find a suitable 6V 2.5A SLA battery from a number of web site or locally at an electronics store. Those batteries are often also used as back-up power supplies for alarm systems, so you may also find in locally from a company that does maintainance on alarm systems.

I don't know much about the battery but it says on it "Valve Regulated Rechargeable Battery".

Measurements are H 3 inch, W 1.5 inch, D 1.5 inch.

I googlized the battery number you cited and found this:

battery maker is Power One
part number 04G10 or KT625
battery rating 6 volts, 2.5 amp hours

Yeah, found that too on Google, Not much info off of that nor anything else.

Thanks though.

ask for eddy and ask him if he can help you out

If you can't supply any more information, can you post a picture of it?
The dimensions don't sound like one of the standard SLA batteries.

I don't know much about the battery but it says on it "Valve Regulated Rechargeable Battery".

While this is my first post, I promise it will not be my last...I realize this is a very old thread, but don't think I here just to tell you guys how a $30 Brinkman flashlight is so great that it MUST be restored .

I can tell you a bit more about the OEM battery...it is a 6V 2500mAh SLA. It's outer dimensions are 76mm H x 43mm W x 35mm D. The embossed code on the top mentioned by the OP is a date/batch code, and does not indicate the model. I have searched for this battery on the net (as well as checking Batteries Plus), and it appears to have been a spec part just for this product with no direct replacement...you gotta love the planned obsolescence business model.

So, rather than talk about what ain't, I want to explore what can be: How to build a pack that meets the voltage spec (or even over-drives a bit, if possible), utilizes the on board charging circuitry and hopefully exceeds the 2.5Ah rating.

What are my options? I am naive to even hope for the possibility that I can use a NiMh array with the on board charging circuit intended for use with sealed lead acid? If so, I guess it's going to be very limited. If not, I am considering AA or 18650 configurations.

Thoughts? Send me on a journey, here folks.

BTW, my quest has already LED (haha) me to the conclusion that a Mag 2D and a couple of miniMag conversions are eminent, but I'll join in on those threads later.

If you're going to stick with the charging circuit you'll have to build a 6v pack out of nimh cells. Most likely this is not a true lead acid charging sequence of cc/cv. It's probably some sort of trickle charger so it'll work with a 5 cell pack. If you've got a little bit of wiggle room you may be able to fit a 3 over 2 cell hump pack of sub-c cells which makes a pack dimension of about 1.7"x1.7"x2.6". These are available in RC car 7.2v battery packs with capacities easily exceeding 5000 mah, more than double and they don't mind being completely drained either unlike lead acid. You can also buy ready made receiver packs from hobby stores but generally these you can only get in lower capacity 3000 mah packs. The ~7.5 volts that trickle charge these cheap lead acid applies right around 1.5 volts of power across each cell in a 5 cell pack so it should trickle charge just fine. If space truly is a concern you may have to make your battery out of AA cells. If you want to maximize battery life and quick charge the pack though you might want to gut the electronics from the charging circuit and just connect straight to the battery and buy a nimh peak detection charger and wire the plug into that.

 

[Mojito150]

A 3 over 2 pack of sub C would be very tight, but may be possible. I could definitely fit 6 AA, though.

Here's where I prove my Newb status...I thought maximizing battery life and quick charging were pretty much mutually exclusive(?).

 

[Mojito150]

OK...if I build a pack, what's the best sub-c out there? So far, I am having little luck finding them other than the Tenergys at BttyJcn.

 

[Mojito150]

I just found a 6 x AA holder that fits into the available space. I'll probably load it with a set of Eneloops I already have to test, then order a set of 2700mAh Sanyos if it goes well.

(I also ordered a TLE-5EX and IQ Switch for one of my miniMags today)

 

[bshanahan14rulz]

Sorry for old thread bump, but can anybody confirm the power adapter specs for charging?

 

[ectoglow]

It sounds like the battery criteria is now:

6v
2400mah - 5000mah
5 cell (AA sized cells)
"Hump" configuration needed to fit
$8 - $18 (preferred price range)

Has anyone found something that satisfies all these (assuming they WILL work in the flashlight)? Mine just dies and I want to replace that KT625 SLA.


This one is probably to big (wont fit), and way to expensive, but spec wise, would it work?

Let me know. Thx.

I too have a need for this battery for the Brinkman spotlight. Thing is, now you can get this same spotlight for less than a battery costs for it. Here's a link for one on Amazon.
http://www.amazon.com/dp/B000NUPD0Y/?tag=cpf0b6-20
Only $19.98 with free shipping. But, the wife and I have now decided to just use the old standard Energizer dual D cell flashlight to find and pickup the dog droppings in the backyard at night. Too hell with spending money if we don't have to. Now, I'll toss this useless junk in a box in hopes I can come across a new battery one day for $5 or less. I'm over it.
