Hey, battery nerds on mastodon. Don't mind a bear asking but do y'all cycle Ni-MH batteries? I know they're not Ni-Cd that has a "memory effect", but idk I feel like these batteries last better when cycled at least once.

Also what charger do you use for Ni-MH batteries? If you've got those fancy Li-ion/LiFePO4/Ni-MH battery chargers with adjustable charging currents, what mA do y'all set it on ?

Also an optional question, aside from eneloops and LADDA's (IKEA ni-mh batteries), what are some other reputable brands for Ni-MH batteries? Preferably reasonably priced. I don't got no income to spend on batteries yet so am looking for pretty affordable ones other than those two.

Idk, boosts are welcome but not really needed. I just wanna read at least one opinion or something but more would be definitely better. Thanks in advance.

Edit: just made CD in "Ni-Cd" to Cd up there. Nickel Compact Disc sounds funny

With all the technology we have, you still need to power down a device in order to have it's {lipo} batteries charged at relatively controllable temperatures.

That's the reason why removable batteries are a logical thing. That is also the reason why I do not understand from the perspective of fire safety, that volatile power units are permanently sealed in devices.

I have a few obsolete Android devices that are still perfectly usable, for lighter tasks. I refuse to pry them open in order to replace the volatile batteries which are charging at temperatures where the devices need to be shut down. A procedure I cannot do, because the power buttons and the logic integrated circuits behind them are broken. I need to use PPE in order to charge those things safely!

Luckily The European Union got fed up with this sealed battery phenomena and thanks to the Europeans we shall have normal battery separation again in our devices

Sagt mal, könnt Ihr mir ein ordentliches #Akkuladegerät für #NiMH-Akkus empfehlen? Meins (vor x Jahren mal bei Lidl oder so gekauft) meldet die Akkus seien voll, aber sie halten nur wenige Minuten, bis die Spannung gegen null geht. Auch bei neuen Zellen.
Das neue Gerät sollte idealerweise auch einen Akku einzeln laden können bzw. 3 Zellen, weil ich viele Geräte habe, die immer 3 Batterien brauchen.

Zolder opruimen; jaargangen KIJK doorlezen (deel 10/veel):

Juni 1987 - Met aluminium-batterijen zou de elektrische auto weer een kans krijgen. Bereik 115km is voldoende. Of een natrium/zwavel accu.

Pas in 1996 kwam de GM EV1 met lood- en NiMH-accu en in 1997 Toyota RAV4 EV met NiMH-accu.

People recommending you manually use a CC/CV power supply are not helping you 😉

Good chargers will let you set what *type* of battery it is, and will correctly charge all major types. I've got a four-cell (four independent charging circuits) that will happily charge NiCad, Nickel Metal Hydride, LiFePO4, Lithium-ion polymer, and a few others. It mostly autodetects the correct type.

They're not stupidly expensive. The model I have is currently $37 Canadian from Amazon:

Непросто было найти крону аккумулятор не на литии.

Не, я понимаю, что ёмкость больше. Я даже понимаю, что кому-то зарядка батареек через type-C может казаться удобной.

Но в гитару такие батарейки ставить банально нельзя - их преобразователи шумят.

Ist das normal, dass an aufgeladenen #NiMH-#Akkus eine Spannung von 2,1V anliegt (mit dem Multimeter gemessen, also mit hohem Widerstand)?
Eigentlich haben NiMH-Akkus doch eine Ladeschlussspannung/Nennspannung von 1,2V; es sollten also nur maximal 1,2V anliegen, oder?

Für alles andere bleibe ich definitiv bei #NiMH, aber für solche Sonderfälle ist das schon nicht schlecht.

Man muss aber china-typisch sehr aufpassen, welche 1,5V Li-Ion Zellen man nimmt und wo man sie kauft, da ist nämlich eine ganze Menge Schrott erhältlich :-) ... Die hier gibt es auch bei etablierten deutschen Händlern, was generell ein eher gutes Zeichen ist.

Die aufgedruckte Kapazität hab ich nicht nachgemessen, wäre aber gefühlt skeptisch, ob das so stimmt.

(4/4)

Die 1,5V #LiIon-Zellen (Größe AA, integrierter Spannungswandler) haben sich in den in den Heizkörper-Thermostaten (#DANFOSS Eco) richtig bewährt.

Seitdem ich die Temperaturen via #BLE auslese, sind 1,2V #NiMH leider endgültig keine praktikable Option mehr.

Ich habe dann herumgesucht und die relativ neuen 4150 mWh Zellen von #XTAR als mögliche Lösung ausprobiert.

I don't suppose anyone knowledgeable about #Batteries and their charging mechanisms might have some insight as to what's going on, here...

This is the rechargeable battery for my new (to me) Phillips Velo PDA... It appears to be two #NiMh cells tap-welded together, with a conductive band close to one end that has a lead going to this mid-point, presumably so the PDA knows it's allowed to recharge this one.

I'd like to recreate it, if possible...
