Did the trickle start immediately after charge ends? Otherwise it would be only a problem for ppl who let the cells long time after charge end in the charger
Just use the eneloop charger for your eneloops, they fit both AA and AAA. I have an old Efest 4 bank that I still use exclusively. It's never faultered and has charged everything lithium based that it can touch both end of...so far. Lol
I don´t have an Eneloop charger and not many Eneloops
I have some older, slow chargers which charges with ? mAh, the C3100, Vapcell S4 +, VC4SL
Even though six months after your question you’ll sure have a new charger, this is my path in case someone finds it useful.
In a similar case I was looking for an advanced charger as a complement for my BQ-CC65 and my Eneloops.
Due to I was interested in: 1) no tricke charge (Eneloop = LSD) , 2) 1,0 V final discharge voltage (IEC capacity test), 3) no-sensitive IR charger (BQ-CC65 is terrible), my only (and better) option and finally acquired has been the discontinued SkyRC NC2600. The MC3000 was too much for me, I didn’t consider.
MODEL / disch V / Trickle / Battery IR / If High IR
———————————————————————————————-
SkyRC NC2600 / 0,5-1,0 / OFF,10-30mA / YES / Charges
SkyRC NC2200 / 0,9 / 50mA / YES / Max Charge current according to IR
POWEREX MH-C9000 / 1,0 / 10mA / NO / No Charges
POWEREX MH-C9000PRO / 0,9 / 10mA / NO / No Charges
The Battery IR value was only a complement for me, I don’t know about this value accuraccy, but it’s interesting NC2600 charges ‘old’ Eneloop Pro (BQ-CC65 refuses in 5 seconds….) indicating > 300 mOHM, a 3-4 times the IR value seen in a white ‘good’ Eneloop.
About the new NC2200, seems the substitute for NC2600, but acoording to the manual the app only permits viewing, no any ‘interesting’ paremeter can’t be configured.
About Powerex MH-C9000Pro, specificates 0,9V as final discharge and ‘matches IEC test capacity’ (requires 1,0 V). I asked MAHA about this and said ‘I will pass this information to the engineering team.’….
What I’ve seen is in most of actual chargers called ‘PRO’ really are almost ‘black boxes’, except the currents, no any more can be modified.

My Vapcell S4+ discharge NiMH to 0,86V, my Accupower IQ338XL to 0,9V, not sure about my other chargers.
it may be so, but I use IKEA branded chargers and I have so many ikea branded AA nimh LADDA 2450 batteries…and the POS charger (I have 2) gives me errors on its own batteries. and understand that these batteries were all new from summer 2021.
Have 2 Panasonic chargers for Eneloops and no problems for 7 years.

sure…but here I am saying the opposite. so were at 50% accuracy between us. or that, or the ikea chargers are garbage.

Someone suggested a charger made to only charge the type of battery you are charging would be wise choice.
Which is pretty much a clear indication that they really don’t understand different battery chemistries and charger capabilities.
Any GOOD NiMh charger can charge ANY GOOD NiMh. Seriously worn out or dead batteries can be a different issue.
A lousy charger can damage almost any battery over time.
I picked up a used very large assortment (AAA, AA, C, D) of EBL NiMh batteries and an EBL charger. They only reason I got it was because I got it for a dirt cheap price, almost new.
The batteries are ……meh, but for the price (like 20 cents/battery), well worth it.
I checked out and tried the charger. Not worth using. I have much better ones.
Not sure if years of the cells are a standalone factor which says something
How many times it was loaded, loaded with high current and so on …
Since I have chargers with capacity test I test sometimes the capaity of the cells, and yes, some older cells have a low capacity. But this was “visible” if I use these cells in my flashlights or my floor lamps with motion sensor, even n my weather stations (one of it discharge the 3 AAA cells in 1-1,5 months).
But overall I can say the Eneloops and most of my other cells can be used for a long time with many charge cycles, at least the Standard Eneloop, not sure about the Pro or other high capacity cells.
I have also some EBL cells, overall it´s OK for the price, I found much more worse cells from other brands.
