Intellect NiMH Battery for Airsoft AEGs with Small Tamiya Connector
(Size: 8.4V 1600mAh)

"I bought two of these about 11 years ago and they still work. In comparison, the battery that came with one of my guns lasted 3 years before it became entirely unusable. After 11 years, the only problems I have encountered so far are a somewhat loose connector on one and the shrink wrap holding the cells together started tearing on the other battery.

Issues & how to prevent/fix them:

- The connector became loose after about 3 years and most likely happened because it would fall out of the battery compartment whenever I removed the battery (M4A1 and G36C handguards). This has not had any effect on performance and can be prevented by laying your gun down on a flat surface while opening the battery compartment.

- The shrink wrap holding the battery cells had a small tear on the end opposite of the wires. The battery arrived in this condition but functioned without issues. After a couple years the tear became bigger. This can be fixed with electrical tape, and for me the electrical tape has been working for at least 7 years.

- The batteries may overheat while charging. This issue affects every rechargeable battery. If you don't have one already, you should buy the Tenergy universal smart charger. That charger has a temperature sensor and if the battery overheats, it will stop charging until the battery cools to a safe temperature. It will also stop charging once the battery is fully charged. I have found that a rubber band is the most effective at keeping the temperature sensor attached to the battery.

Compatibility (I know for a fact that the battery will fit in these guns):

- G&G M4A1 (front-wired) - The battery fits in the handguard with plenty of clearance. It will work on any TM compatible M4 that is front wired to the handguard. Magpul MOE handguards will also fit the battery with clearance.

- JG G36C - The battery fits in the handguard, but is a tight fit and you need to be careful not to pinch the wires. The G36C is the smallest handguard for G36's, so it will probably fit in any front-wired G36. The butterfly configuration is best for this gun.

- G&G M4 (rear-wired) - The battery fits in the crane stock just barely. It is a pain to put in the battery on this gun. The butterfly configuration works, but there are batteries that are specifically designed for crane stocks that will fit better. It may or may not fit in different stocks.

- SCAR-L (rear-wired) - It fits well in the stock with a little clearance. It is likely to fit in any brand SCAR-L or SCAR-H.

- CYMA AK-47 (rear-wired to stock) - The battery fits, and there is enough space to hold a spare battery of the same type. It will fit easily into any gun that uses large-type batteries with a small tamiya connector.

Conclusion:

If you are looking for a small-type battery for your gun, this battery is probably the best non-Li-Po battery available on the market. Yes, it costs more than other brands, but it is definitely worth the extra money. It will last an incredibly long time if you take care of it. The long-term cost is lower because you won't have to replace it after 3 years. I recommend the butterfly configuration instead of the normal brick configuration, because it will fit anywhere that a 9.6v small brick battery can fit, plus crane stocks.

"10/10
I use this battery in my AGM MP40 big difference in rps and charge compared to a 8.4v 1100MaH that my gun came with

"It does what its supposed to and holds up decently. For the price definitely recommend
