Flash AA 4600mAh (Yellow-blue)

What do you get when you buy batteries rated at twice the normal capacity for NiMH?



Official specifications:

• Type: High Capacity 4600mAH
• Estimated recharge times: Up to 1000 times, expiry dated 2018

Maximum temperature raise at different discharge currents: 1A:+1,7°C, 2A:+4,0°C, 3A:+6,5°C, 5A:+11,5°C, 10A:+13,2°C
Capacity is less than 1/3 the rated capacity, I will not call it a surprise.













The curves do match fairly well, but the batteries has low capacity and the voltage is lower than eneloops.















Conclusion

If the batteries had been marked 1300mAh, they would have been good low capacity NiMH batteries.

To answer the question from the top: You get cheated.
