Is there such a thing as long lasting AA batteries?

My main use for AA batteries is in my Speedlight Flash at shows or events. It’s worth noting there are different types of batteries available

  • Alkaline AA batteries
  • NiMH rechargeable
  • Lithium AA batteries

I have been using Sanyo XX High Capacity Eneloop Ni-MH 1.2V 2500mAH rechargeable batteries in my flashes for a few years. They are amazing for lasting power and low self discharge. They are also known to maintain 85% of their charge after 1 year of storage. The eneloop pro batteries can be recharged up to 500 times.

A good charger is also important to condition your batteries. I use the Fast Smart Charger for 1 – 8 AA or AAA NiMH batteries with a LCD display.

Charging times for my batteries  is between 1.2 hours to 5 hours depending on the initial battery level.

I am always looking fot the best flash recycle times so purchased a new pair of Vapex AA 8 x NiMh+ Rechargeable Batteries.

What’s New?

  1. The batteries are ready to use as soon as you have removed them from their packing.
  2. They will stay ready for use for over a year without the need to recharge


Type AA Nimh+
Capacity Nominal 2500mAh (about the same as a good non-rechargeable)
12 months About 70% of charge is held (normal nimh would be empty)
6 months About 80% of charge is held
Capacity Rated 2400mAh
Weight 27g

I am using these at the moment so will provide a further update post with my findings.
