e-mag charger voltage/charging issues

[om3n]

So I just bought some e-mag lowers, and I got them TODAY and I just got done playing with them for the first time, and I couldn't use e-mode at all because the battery that came with them was pretty much dead when I got it and I didn't have time to charge it unfortunately. Of course, mech mode (what I'm used to) worked beautifully. It took alot of messing with the sear to get it to fire in mech-mode, but it's working great. I love my e-tac


WELL.... I got home just now and realized that it came with the charger, but no cord to charge it with

So I looked at the input on the charger, and it says DC 10-15 volts. I went to check out the power supply on my electric keyboard in my room, and it outputs DC 10 volts. Sweet. So I plug it into the charger, and it fits like it was designed to be there :) Well, I plugged it into the wall, and when I did that the light turned RED for a second on the charger, more like 1/4 second, and then it turned green... doesn't green mean fully charged?? The LCD on my mag was showing that the battery was low, but when I plugged it into the wall charger it's showing up as fully charged. What is going on? I am leaving it in the wall just in case, but is this normal? And am I safe with my 10 volt power supply?

Thanks guys

Make sure your 10v dc supply has the capacity to deliver 1 to 1.5A of current.

The green light will come on if the battery is not making good contact with the charger or if there is a bad battery.

Bad battery? That's possible... I have no idea how old this battery is- how would I check this?

It should go red then green as it is trickle charging. These batteries take a few hours to charge up fully and 12v input is recommended. The battery charger should output around 23-26 volts when working correctly, And a completed charge should read 18-20 volts in the battery. I like to charge them for 8+ hours. An hour in the car on the 12v cord won't really do it.

Easiest way would be to leave it on the charger for 10-12 hours and see if the battery holds the charge. The red/green light is a more of a current indicator than a charge/complete. I've had new batteries that go green in a couple of hours, but still not fully charged.

Well mine went green in less than a second :/

What is the disadvantage of using a 10v power supply?

Also, I'm only getting 700mA out of my power supply too... is that not going to work well?

[athomas]

A 700mA output means you are not going to fully realize the charge capability of the charger. It could also affect the charge sensing, but that is just a guess. I don't know how the AGD charger specifically functions. The low capability combined with a low input voltage could affect the operation and maybe the reason you are getting a premature green light.

If the battery voltage reaches near its capacity, the charger switches to its trickle charge mode. This is when the green light comes on. The voltage that is selected for this is less than the full capacity of the battery pack to protect it from overcharging. It is then topped up and maintained on trickle charge. Depending on the starting condition, the capacity, and condition of the battery pack, the exact time for each pack to reach the trickle charge state could be very different.

I have 2 batteries one charges as advertised and the other goes red/green the second I plug it in. Both hold charges and work properly so I don't see it as an issue. Could be that the battery is going bad but I guess time will tell.

Well I just played with the battery after a little while of messing with it, dry fired about 2000 shots, and now that I have plugged it back in the led on the charger is red and has been for several minutes now. Would it be worth investing in a better power supply for the charger?

Yes. The one that comes with it from the factory(12volt) or the radioshack 12v 1500ma wall charger.

Ok, how much does the radioshack charger generally cost?

Also, does anyone have an extra battery saver pin they wouldn't mind giving me/selling to me I also didn't seem to get one of those with my lowers either.... They cost $2 each from the AGD store, so if anyone is willing to sell me one I'd pay for shipping and for the pin.

EDIT

well I was looking through all of my electronics that I own, and I found a 12v 1.5 amp power adapter

It's now charging up my battery... now about that battery saver pin. Does anyone have an extra one?

Use a plastic golf tee. That's what I used after I lost both of the pins that I had. It works great. Just don't get one that is too fat or it won't fit in the hole.

Sometimes you make things so simple

wow that is actually a good idea- believe it or not, I tried several things that wouldn't fit before you posted this, and among them was a wooden golf tee that wouldn't fit lol

I will try to find one, but I really would like to have an AGD one.

by the way... I LOVE my e-mag. It's so easy to walk, but I will perfect walking it, and this will probably be the last high end marker I buy. I can't believe more people don't have these.

[fishmishin]

I got to play with my first e-mag yesterday, and I would totally have to agree with you. I like it better than the 07 Ego I played with for awhile this summer. I still have a good deal of work to do to mine to get it like I want it though.
