Autonomy announced is 2500 mAh / 2400 mAh for about 500 loads.
Clearly it is better to invest in a lot of 8 AA batteries for about 15 uros only 4 AA batteries for 10 uros!
For "Energizer" is also the rechargeable batteries + preloaded 'for about 10 uros 4 2300 mAh Batteries:
Energizer - 635 730 - Severe 4 HR6 Rechargeable Battery - 2300 mAh.
Now this is a KNOWN Brand & RECOGNIZED I personally use my eyes closed for many years!
Furthermore, this battery Lot, we must not forget to add a Energizer - Universal AC! Unless you already have one, here you are with a very inflated bill ...
Level autonomy, I tested them with my Canon Powershot SX 150IS 14.1 Megapixel Digital Camera Black is a glutton. And for now, still no need to change!
What should have been an innovation is if "AmazonBasic" had included a 'POWERCHECK' (integrated load tester).
For a similar price, it is necessary as always wait until your indicator blinks to change batteries ...
In conclusion, GOOD rechargeable batteries "AmazonBasic" to see in time ... But I remain blocked on the fact to prefer buying a Brand Leader in the Market!
