8.4V 1600mAh NiMH Flat Battery Pack for Airsoft Guns

The first thing that was great is that it was here in only 2 days for around $6.50 shipping. I was surprised at how fast it arrived. It came in a paper package and the batteries were bubble wrapped. The batteries are in perfect condition and are very reliable. I haven't tested them with my gun yet, but my looking at other reviews, I'm not worried! I definitly recommend buying. Great deal, great shipping, great battery.

Shipping was super fast. I replaced the stock 1100mah battery which came in my "refurbished" MP40. I didn't realize how bad my old battery was! Firing rate has doubled! So far, I've had no problems with this battery. And I really appreciate the recommended charge rate in the product description. Takes out the guess work!

...at least for my gun, JG G36c, that extra 1/8 inch black cap circumference had to be eliminated. I cut into the surrounding side portion of the cap with heavy wire snips starting at the valley between the battery rows, clipped up to the wires, took off the cap, trimmed off the surrounding sides, and slipped the top portion of the cap back on and resecured it with electrical tape....thinnly, of course. Hey...now the front of the gun fits just like the original battery that came with it. I'm not recommending doing this, I'm just saying what I did. I purchased 2 of them with the smart charger...if needed in the future, I'd probably still buy these batteries and modify them again...no big deal to me.
