Ordered the new editions:
BK-4MCC/8TN
BK-3MCC/8TN
directly from Japan now. (I just wanted the newest). But they was not free…$6.5/battery when I order two 8 packages of AA and one packages of AAA.
Anybody that know the real price per package in Japan?
Prices in Japan go up and down almost daily. These are new, so probably around 20-25 usd, shipping would be another $4 per pack. PayPal eats $1,50 and they take a $1 exchange fee again when you withdraw the money in Japanese yen.
You can do the math. But 6,5usd per battery you paid is quite a lot.
It was from the first and then only seller in Japan I got them, now there is several sellers from Japan, and the price is down to around $3.75/battery. Still direct from Japan.
Can you read the circular picture on the package (from my picture in my last thread) and confirm/not confirm that this is the 10 years batteries as well? I can see the number 10 there, but don’t understand the rest.
Might be because most people don't know about them, and therefore sellers are less likely to sell them. With this in mind, they are usually more expensive than other brands outside Japan, that it's difficult to sell them..
Don't know exactly but I thought this could be the case ;)
All the talk about fakes has me worried about ordering online. What about a trusted source like walmart with their free store pick up like this Robot or human?
My understanding of the 90% after one year, 70% after 5 years etc just say that if you buy a package and it’s one year old, the batteries has 90% capacity. If you charge the battery, it will have 100% capacity again. And you can recharge it to 100% 2100 times, or 1900 times or what it says on the package? Anything else will be bad practice, if a 5 year old battery, new out of the box, just can be charged to 70% max, all 2100 times.
I think there are enough tests here and at CPF that will show what I meant.
What do you mean by "buy first generation eneloop made back in 2009"?
In Japan its very hard to find anything older than 4th generation eneloops, and in Holland I havent seen them anywhere for sale yet (in a street store). And in 2009 we got 2nd gen cells.
They just confirm the 70% energy left after 10 years, i.e. nothing about the full capacity of the battery, that must be at least 70%, but as know from other testers it is larger.
Unfortunately, these terms always get mixed up. Almost everywhere.
Capacity (Ah) (more exactly: discharge capacity) is how much charge a battery can hold. Like the capacity of a bucket.
Charge (Ah) is how much is actually inside, i.e. how many Ah you can draw from it until it's empty.
Energy (Wh) is, well, energy. Similar to charge, but voltage also taken into account.
If a 2000mAh/2400mWh battery after 10 years has 70% capacity left, it is degraded to a 1400mAh battery.
If it has 70% charge left, then there are still 1400mAh inside, but it could still be a full capacity 2000mAh battery (i.e. one can recharge it an then discharge 2000mAh).
If it has 70% energy left, this means 2400mWh x 0.7 = 1680mWh energy. It says nothing about charge or capacity.
