Seriously, I have no idea what null is for - null characters, null processes, errors, null strings, nil, nada, nothing, blank, empty?
I really don't see the point of null when it's not specific enough to determine what is null. Maybe a retag is in order?
When my supervisor pitched the PhD to me, it was all about analyzing "big data". I had BSc/MSc experience in wet-lab biology (mainly culturing cells), however I wanted to branch out into Bioinformatics since I am, and always have been, fairly good at programming in C, and data analysis in general...
amazon.com/… then for AA & AAA only and for super battery geekoids who would go through endless BS to charge, discharge , cycle , break-in, and get complete readouts and capability this one is bestest
Both of them would still have the problem the one reviewer said about Rejecting batteries that are no longer "good" which also means they wont cook bad batteries either.
Well, nickel-based chemistries can be tricky to charge properly. The best charge routine involves detecting that the cell voltage has dropped a tiny bit after increasing continuously under an input current.
This is called delta-V charging.
Detecting this tiny drop can be difficult, which can cause the charger to overcharge and damage the battery.
It's not like lithium-ion, where one could just apply a certain voltage (generally 4.2V a cell) with a current limit (e.g. 1A) and stop when the current drops below a certain point (e.g. 50 mA).
problem is even nickle based could have used a li-ion charging routine of the same type, for the nickle voltage. li-ion was "new" and with it came what i deem a more proper charing method for anything .
New , new :-)
but the Faulter method for ni-?? is so engrained and trained and booked, and teached, that no one can even make one using a "new" method without "experts" rejecting it as bad.
there are 2-3 out there that do use that method though. they are also li-ion chargers , and so they just used the same alogrythm with the different voltage.
Maha (instead) just puts in a "voltage max" into a normal (old school) nickle charge routine, which stops painfull overcharges (most times) and then finishes up with a "topping charge" while most chargers are still reaching overcharge state, oxidising the battery and using that as a stop method.
The old school method is still completely valid, and doesnt destroy the batteries too badly, because manufactures of the battery have insured and tested knowing that the beat it till it faulters method is what is most likely to be used.
@Psycogeek Almost $90... Pricy. My needs are AAA/AA NiMH recharging and I could use 9V batts too.
@Bob Is it not good for AAA/AA NiMHs?
LCD is a plus but I ma looking for one that unlike most would ensure longevity of batts giving love to each battery instead of using common recharging scheme that degrades battery lifetime.
@bwDraco difference is, charging Ni incorrectly just reduces lifetime, or may cause minor venting. Charging Li incorrectly often results in fire and toxic smoke.
[Though this late answer may get little exposure now that the question has exited the hot-list, I think it is essential to further emphasize the contrast between the comprehensive safety features in devices such as laptops and cellphones vs. the typically far less comprehensive safety features in...

The crowded commuter train one is also interesting
@Bob I don't recharge consistently so I don't have average but if I expect I will be working with device requiring batteries like projector for several hours I will usually recharge between 4-8 batts that day.
@Boris_yo I've not seen a projector that takes NiMH...
I don't even use AA much anymore... I might recharge em maybe twice a month. At which point iot'll take me decades to go through the rated 500 or so cycles.
lithium batteries will Blow up, that is soo cool, now where is my nuclear one :-) with all the fear, i have actually had more incidents with lead acid , ni-cd , and ni-mhy . As a kid I blew up a car battery in my face. Had a super explosion of a few china D cell ni-mhy . and a small fire from very high power ni-cad pack in the back of the van while driving down the road.
but as of yet, even after dealing with way more li-ion cells and lithium primary, no cool explosions yet, even from some pretty extreeme testing. Sure the fear helped to educate and control, but any high powered battery (or set) can short out , or charge badly and burn your house down. The only difference with lithium is the contents of the battery itself can make fireworks.
with Much Power comes great Responsibility , just like mods :-)

How do you stop Chrome from reloading all tabs after you recover previous sessions? I have 2 windows with 67 tabs and sudden reloading puts a burden on CPU...
@Bob I think they were probably crappy ones. But that leaves me with a few spare sata power connectors so might try using them to rewire the power supply.
i've noticed recently that a very high rep user is just answering with single line answers or link only answers that should really be comments. What should I do about those sorts of answers?
yes you know the advice you are getting is top notch but seeing that a super high rep user has answered might stop better more accurate answers from lower rep users

@JourneymanGeek I ended up with some Paracetamol/Phenylephrine/Dextromethorphan mix (Codral, Dimetapp, etc.). It works for coughs, but not so much for sinus issues :\
@JourneymanGeek Codral Original does too. Ended up picking up a pack today. Though I'm feeling a tad better now so I'll hold off on it at least till tomorrow.
