The Ikea batteries that I have are the green and silver ones made in China so that probably accounts for their poor performance.
Ahhhh……YEP! hat would most definitely account for it.
lol
LADDA (plain white with black lettering)…not the cheap green & silver ones.
I have these and they usually test out at 2800mAH+ when new.
And I don’t know how old your HarborFreight batteries are, but the newer ones are quite good.
Maybe 4 or 5 years ago they really upped their game on their Best Rechargable batteries.
(Not the old Orange ones, those were crap)
For capacity and quality, the ones they sell now they’re not easy to beat for the money. My local store is often sold out.
HF has a lot of junk. But their top line of NiMh rechargable batteries rock.
