Ancient idea, today's technology with quirks

Bought 3 packs = 12 HQ NiZn batteries AAA.
Unfortunately, only 4 were actually recycled, the remaining 8 seconds "loaded" between 0.3 V to 1.4 V. In NiZn Charger, they were just as quickly back down.
In my question to the community have responded to me 5 hard-working helpers - thank you! - Now the 8 items as returns go to England.
Who needs scrap, hopefully I can see from the purchase price and costs a small refund ....
