Some things will only work with the full 1.5v, not 1.2v from NiMH batteries.
Poll: Time to ban alkaline batteries?
- Thread starter clv101
- Start date
That would have to be a particularly badly designed product - alkalines don't stay at 1.5v for very much of their lifetime at all. Alkalines voltage vs discharge curves are steeper than NiHM - sure they start of higher, but relatively early in their total life fall below NiMH.
Pretty much the same here
I think when my current supply of duracells run out (only use them in remotes/clocks and a couple of torches), i'll be buying more hybrios to replace them, as the rechargeables don't cost any more than decent non rechargeable batteries.
However I think it's a bad idea to ban alkaline batteries quite yet, as there are still devices that may not work as well with nimh, or that will likely only use a single battery a year (clocks) etc.

That's pretty impressive. I will look into that.
Indeed, my thermostat only works with alkalines in it. It won't switch on if I put my GP rechargeables in.
Yeah, I guess there are still some things that need them. How about a minimum price on alkaline such that they are at least same price as NiMH? Dunno what that you be, kinda like a minimum price of £1 a battery or something. Bit like the minimum alcohol price they are talking about in Scotland. Just so there is no price incentive to buy alkaline, they are available if you specifically *need* them, but otherwise buy LSD NiMH.
I have the Uniross version (Hybrio) in my keyboard and mouse. Compared to the old rechargeable batteries, which I had to swap & charge every week or two, these new LSD batts are incredible.
They last so many months between charge that I completely forget I'm using wireless devices
I think I charge them twice a year, maybe.

As my various batteries run out I've been replacing them with eneloops as once you have the recharger most applications only benefit.

We're not just arguing about batteries now (batteries? really?) but actually calling for a type to be banned? And there are graphs?
This has got to be a new low.

I have a set of the Hybrios, there great cant fault them. Been using rechargeable for years where possible and there a lot better than they used to be.
It wouldn't be so bad if batteries all got recycled but i'm pretty sure most people will chuck them in the bin once dead.
I'm no expert, but there's Li-Ion, and Li-Poly, so which Lithiums you talking about?
Also don't Lithiums have some serious problems? The early ones had the memory effect thing, and I read somewhere that fully discharging the newer Lithiums seriously damages them (you're supposed to keep them topped up).
But then, as said, I'm no expert.
I'm talking about 9v batts, and its the peak voltage I need. When my gat stops running off of a 9v I can take it out and continue to use it in other devices. I use less than half of its actual capacity before it is unable to operate the solenoid properly. Also, keep in mind I only use the best batteries as standard brands are often a let down, non brand batteries often behave as though they are dead when I stick them in. What quality battery was used in that test?

Both use lithium ions and perform comparably.
They don't suffer from memory effect. And I've never had any problems fully using lithium batteries, there may be a problem if you leave it fully discharged but who does that?
I am actually leaning towards it being true too. I've had some eneloops sat in one of my Wii controllers for well over a year without using it at all (boxed up in a cold loft). After bringing it all down for a game I was finally interested in on the system a couple of months ago, i automatically assumed that they would need charging. Not so it seemed, they lasted for a good 10 hours of game time before they started to give the battery low warning.
Doubt they were even fully charged when the controller was packed away too. Eneloops are just brilliant.
Sanyo Eneloop are my favourite, they have the lowest discharge over time that i know of, as a result they're actually useful for things like clocks and TV remotes.
Hybrio batteries are also excellent, however from what i've read their latent discharge (as in, losing charge even when not in use) is slightly higher than the Sanyo. They are still miles better than 'normal' rechargeable and are a bit cheaper than Sanyos. Certainly not a bad investment if you'd like to start cheaper as a test run, like Sanyos they're rated to last for over 1000 recharges.
Buy a good charger though, pick a bad one and you'll end up killing the batteries much faster. I bought an official Sanyo charger for approx £20 which came with 4 batteries and it works perfectly, though it is very slow, overnight charging is essential, spend a bit more however and you can get chargers that are much, much faster.

It's not the length of time they hold a charge, it's the capacity.
In a low drain application a good alkaline can have 3000mah+ capacity, wereas an Eneloop will typically have 1900mah - meaning the alkaline will run something like a clock, remote control or smoke alarm 50% longer than an LSD NIMH once self discharge is taken into account.
