Vapex instant AA 2500mAh (Silver-green)





Official specifications:

  • Capacity Nominal: 2500mAh (about the same as a good non-rechargeable)

  • Capacity Rated: 2300mAh

  • Weight: 27g

  • 6 months: About 80% of charge is held

  • 12 months: About 70% of charge is held (normal nimh would be empty)



Maximum temperature raise at different discharge currents: 1A:+1,4°C, 2A:+3,6°C, 3A:+6,2°C, 5A:+12,5°C, 7A:+18,4°C, 10A:+18,8°C,
I got these battereis from Ebay. Their capacity is slightly lower than rated, but not much.











The discharge curves looks fairly decent, expect they cannot do 10A















Conclusion

The cells are not top performers, but they are fairly good.
