I haven't returned it and did some more test.

I charged it to 100% and after 4 days it is at 80%.

This product is very bad at holding charge.

How are you measuring that it's dropped to 80%? These batteries don't have integrated BMSs like lithium ion batteries do, so the ONLY way to accurately gauge what capacity remains is to do a drain test.

Are you just sticking these things into a smart charger and reporting what the charger thinks the capacity is? Or are you using a proper tool?

Assuming a valid measurement regime, your particular unit is a dud, return it.

Battery nerds, should I just get Ikea Ladda's to optimize price and quality? Anyone know a good source for LR44 batteries?

For what it's worth, the Ikea Ladda 900 mAh AAA batteries were Eneloop Pro 2nd Generation (2013-2014). The Ladda 750 mAh AAA are Eneloop 5th Generation (2021-Present). The Pro has a higher capacity but can be recharged much less times than the regular Eneloop.

Get Eneloops if they're on sale and you need to spend a few more dollars to get free shipping on an order. Get Laddas if there's an Ikea close to you. I have and use both.

How many times recharged less are we talking about here? Something like 500 times for the 900 mAh vs 2000 times for the 750mAh?

Thanks! Actually I found some Eneloop AAA from years ago that I've never used still in their original packaging. I might just get a 4-pack of Ladda's since they're cheap enough, and they're new. I need it to power a TI-84. I also have Amazon Basics that were made in Japan (bought years ago). I'm sure I can use my OPUS BT-C3100 to get a glimpse of battery health?
Yeah, Ikea is within walking distance.

2AA+2AAA rechargeble battery (@C$21.99).

The 4AAA is around the same price but not available now.
I bought 2 Packs of the 4AAAs about 2 months ago.

This works quite good for my Qardio blood pressure monitor.
These AAA batteries will run longer than the usual AAA batteries.

Eneloop Pros of any generation are 500 recharges. Eneloops (regular) of the current 5th generation are 2100 recharges.

I bought used the ZTS pulse load battery tester and Opus BT to drain.
