Is it just me or have rechargeable NiMH improved?

These are the ones to get and they aren't terribly expensive given what they are:

https://power.tenergy.com/16pcs-tenergy-centura-nimh-d-1-2v-8000mah-rechargeable-battery/

They have a 'Premium' high-self discharge 10Ah version and a 3Ah 'Centura Lite' version, neither of which seems worthwhile.   I've been using the regular (heavy) Centura model for a while now and they really do hold up.

I don't  use many of that kind, so instead I use an adapter that takes AA and just holds them in the right place. They last long enough, and being able to replace with common stock is better than keeping C or D spares.

I see this one looks good but is a bit on the pricey side:

It looks like the one shown here in this bigclive video, which seems to critique smart chargers but I’m not sure what his final conclusion is except you need to sometimes revitalize batteries that drop voltage too low or reverse and that smart chargers don’t always help inform the user. Anyways, bigclive seems to be using that Tenergy charger I linked above:



I’m looking at something that will do slow charging, I don’t care about speed as I have enough batteries to swap. I just want to make sure it doesn’t kill the batteries. These Duracells mention absolutely nothing about whether they are LSD or similar to eneloops, maybe they make them or maybe they just rebadge them from another supplier and not allowed to use certain trademarked terms? They are obviously low self discharge as they come pre-charged and so far have far outlasted anything I’ve ever used before. I fully expect to need to spend a good 16 hours charging them slowest safest method possible like it says on the package (250mA for 16h). But the Panasonic eneloop charger which comes with 4 AAA at 6h charge time doesn’t tell me anything about how many mA it uses to charge.

Until they state 'low self-leakage' it probably doesn't matter - you'll be binning them before they discharge.

If they're "pre-charged" they must be the LSD kind, otherwise they'd die sitting on the shelves hahaha. These days you honestly just expect it and from a cursory glance on Amazon AU like 70% of listings are LSD.

Changing regions on Amazon is making my head spin, is something like the XTAR VC4 available for a good price? (is that CAD26?) Good to have if you ever want to use some 18650's in a flashlight or something.

Again I urge you to check out this site for charger reviews. Just sort by the smiley faces and see what's available to you.

Don't overthink it too much, these LSD batteries can take a pounding and in all honesty you're probably buying a solid charger that terminates properly. So what if they die an early death and can "only" give you 100-200 cycles before going high internal resistance? I have eneloops from 2009 still serving remote control or clock duty in their retirement.
