Never use recharchables for stuff like TV removes and clocks, basically anything that doesn't consume your battery power in 2 weeks.

The reason is that a TV remote will prolly consume your recharchable in 6 months, 10% by the remote itself and 90% by the battery's self discharge. The Alcaline batteries have a much lower self discharge rate and they will last in your TV remote for years.

@ Sqrl

The Lithium batteries tend to have big problems when you charge them before they completely wear off. Some of my lithium batteries went down to 25% power after I've put them in the charger at 75% power (this was a $75 genuine Sony battery).

Are you sure it was Li-Ion?  Li-Ion batteries  aren't susceptible to a memory effect.

"Unlike Ni-Cd batteries, lithium-ion batteries should be charged early and often. However, if they are not used for a long time, they should be brought to a charge level of around 40% - 60%. Lithium-ion batteries should not be frequently fully discharged and recharged ("deep-cycled") like Ni-Cd batteries, but this is necessary after about every 30th recharge to recalibrate any external electronic "fuel gauge" (e.g. State Of Charge meter). This prevents the fuel gauge from showing an incorrect battery charge.

That's the theory, but practice kills the theory.

Any battery, no matter of it's type lasts longer and holds more power if you charge it 100% after it's 100% discharged.

I'm owning shitloads of batteries of all types and my experience says that Lithium batteries suffers more from the memory effect than the NiMH batteries (ain't got Ni-Cd to test but the difference shouldn't be big at all).

Also Lithium batteries tend to cost much much more than NiMH and Ni-Cd. I seriously doubt the quality of the charger and battery you buy for $10.

Manufacturer does matter. Here's an example for my PSP:
$10 no-name 3600 mAh battery - lasts ~1 hour
$50 Sony 1200 mAh battery - lasts ~6 hours

I have some very cheap Ni-Cd  (the rest of my rechargables are NiMH) in my electric toothbrush, which I rarely use, and yet they seem more powerful than standard batteries each time I do use the toothbrush, so I don't know what's going on there.

normal alkalines will be really strong in the brush for the first 3 or 4 goes, and then they will die a bit, eventually with me changing the batteries when the brush stops if I press it.

These recharchables seem to keep it on full power every time I use it, and have been in for 6 months, it's very odd.... especially considering they are cheap, only 800 mAh and last barely 15-20 hours in my Wii remote. (depending on the game)

Anyway yes, I didn't think of that for TV remotes.

@Sqrl... I agree itis a good deal, but I am happy with what I do (that and I presume this deal is American)

Its not just theory, the reason Li-Ion batteries are gaining popularity is because they actually perform well compared to other batteries.

As I've said already regarding the quality, I'm confident it will be high quality because I've dealt with monoprice before, they sell high quality products at ridiculously low prices, and everything I've purchased from them has followed this pattern so I'm not going to doubt it now, I'll know soon enough though.

The problem you're describing in your anecdote  makes me think that something is wrong with the internal resistance of the 3.6 Ah battery.  A malfunction is really the only explaination for it being outperformed by a factor of 6 by a battery with 1/3rd the capacity.

Honestly I'm not sure that the subject of a simple battery choice is worth all this fuss, but just the same I ran across a site that actually gathers data on this stuff (batterydata.com) and their position is that Li-Ion and eneloop NiMH batteries are roughly equivalent in terms of prices, power, efficiency, etc...The only real differences are the convenainces each offers (eneloop is better at longterm storage while Li-Ion needs less frequent replacement, charging habits don't matter, and it weighs less). Personally, I'm happy to take their word for it until another group of people who have actually collected data and done the research come along and say otherwise.

Well go ahead and buy it. It's only $14 after all ... Let us know of how it performs. Maybe someone else will find it interesting.

The PSP battery I was talking about has no problem. It just performs really bad, lots of reviews says the same thing.
