Update: I have uploaded the figure on AA batteries, the conclusion is pretty the same as that of AAA - hope it helps.
It looks OK, but to be honest, really basic looking. Wait, we are more interested in performance, aren't we? Tried to answer some frequently asked questions.
1. claimed 850 mAh, minimum 800mah, really ?
I tested 2 randomly chosen batteries: 860 mAh and 894 mAh, respectively. I noticed a previous review reporting much less than my findings. A bit more specific, I used a specialized charger with a test mode which full discharge then charge to report battery capacity, running at 500mA discharge rate, room temperature.
2. Does it hold?
Once fully charged, I removed the batteries from the charger, and measured the voltage over a period of 1 month (31 days). As you can see, the voltage does drop a bit the first few days but stabilised in about one week's time and change little for the rest 3 weeks. Really impressive and useful: the voltage remains >1.3v after a month.
3. Internal resistance, what is it?
This is more technical but high resistance may cause the battery to heat up and the voltage to drop under load. The typical internal resistance for new NiMH rechargeable AA/AAA batteries is between 10mΩ and 100mΩ. Faulty rechargeable batteries have a much higher internal resistance.
The tested Amazon AAA has a internal resistance of 15mΩ, both of them. For your reference, I have an old half-faulty battery measured at 120 mΩ.
4. Will it last?
Oh, no, forgive me, not in a position to test them over years! Amazon claims you could charge hundreds of times with minimal power or capacity loss - I will leave this challenge to you...
5. Am I paid by Amazon?
Nope, purely out of interest, and solely out of my own pocket. I am testing other batteries and will upload my reports in due time.
I have been using rechargeable batteries, initially due to environmental considerations and then found actually they save money. Compared to Alkaline batteries, rechargeable ones used to have lower capacity hence introduced complaints. A Duracell Alkaline battery has a typical capacity of 1000 mAh, while an old rechargeable one 500 mAh or less.
With technical advances, rechargeable batteries have been improved a lot. Modern AAA batteries range in capacity from 750mAh to 1100mAh. I bought in Amazon a lot Panasonic batteries (NiMH AAA 750 mAh) and found they were excellent. Unfortunately, I lost most of these batteries due to my home extension mess. Ironically, these Panasonic batteries are becoming more and more expensive over years. Having read reviews, I therefor purchased EBL batteries, and then Amazonbasics and Duracell AA and AAA.
6. Are Rechargeable batteries better than Alkaline?
Yes, most of the time. They’re safe, reliable, and most importantly environmentally friendly. They pay for themselves after a few recharges, even counting the cost of a charger.
After testing AA/AAA batteries from EBL, AmazonBasics, Panasonic and Duracell, I am pretty sure it is time for rechargeable batteries and no more single-use ones to help our environment while saving you money!
