Test/Review of King Kong ICR26650 4000mAh (Gold)

[size=+3]King Kong ICR26650 4000mAh (Gold)[/size]



Official specifications:

• Volt:3.7v
• Capacity: 4000mAh
• Size: 26mmx66mm.
• Charge current: <=1a?
• Weight: 95 g

The capacity is well above the marked value.








The two cells has the same capacity, but the voltage is not the same at higher loads.















[size=+3]Conclusion[/size]

The cells has a good performance, but they has a slightly different voltage when loaded.
I will rate this battery as acceptable.



[size=+3]Notes and links[/size]

How is the test done and how to read the charts
How is a protected LiIon battery constructed

So if we're not using this battery at loads above around 5A it should be perfect, right?

It works fine at 10A load, the difference in voltage does just mean that two batteries might not have the same performance.

okay thanks! i misinterpreted your results.

do you know if they're magnetic ends (like for a CottonPickers charger)? what normal retail charger (XTAR, etc.) would work well for these in the button top style? I think the WP6 II charger may be too short for the button top versions of these King Kong cells but I want the button top

Magnets does work on the battery. For a retail charger I would look at the SP2.

Many thanks for your another excellent review. HKJ! :thumbsup:

Have you tested the INR version of these? How would these compare? Thanks.

Not yet, I have ordered them and will test them when they arrive, i.e. the result will be up in one to two months, depending on shipping time and how many other batteries I have to test at when it arrives.

I own a couple of ICR and INR King Kong.
All of them can be connected with magnets.

I recommend XTAR SP2 charger.
Both flat-top and button-top batteries fit and are charged quick and spot on to 4,20V,
if You give them a second charge, at 0,5A, after LED went green.

thanks a lot you two! I appreciate it.

I'll pick up some of these King Kong cells and an SP2. thanks!

Review of King Kong INR26650 is up.

These suckers are pretty consistent over the years.
I just bought one of these to run in a new 26650 flashlight, and did a quick initial 1A discharge test and this is the results I got:

Measured at 4335mAh / 15.8Wh with a 1A discharge. Rated at 4000mAh, so I'm pretty happy with that.
