Rechargeable alkalines?

[Jacobe Hazzard]

Would these batteries be a good choice for use in a bicycle LED blinking
lights?

The application is low drain, alkaline batteries typically last me about a
year, but I'm loathe to use disposable batteries in anything these days.
I'm told that rechargeable alkalines don't exhibit the same self-discharge
characteristics of other batteries like NiMH.

I would also like to put rechargeable alkalines to use in other low-drain
apps, like remote controls. Interested to hear what people think of them.

some apps do not allow rechargeables
voltage of rechargeables usually 1.2V as opposed to 1.45V for "normal"
batteries

Well, this is bad news for sure, but thanks for the warning guys.

I did have some bad experiences with rechargeable alkalines probably 8
years ago, I was hoping they had improved.

Thanks.

Avoid rechargable Alkalines. They are bascially a gimick and a very
poor choice for almost all applications.
They are a crap technology, have reliability issues, and frequently can
and do simply "die" for no apparent reason. This is the last thing you
want for your bicycle lights I'm sure.

If you are getting 1 years use from a set of Alkalines then I'd say you
are going great, and you should not be feeling guilty about replacing
them once a year. You could perhaps even put the "dead" ones to use in
very low power devices like a wall clock.

Perhaps you could even try D cells with a DC-DC converter to give you
much high capacity than say AA's.

For infrequent use long life items you simply cannot beat
non-rechargable alkalines, and the newer lithiums etc. Rechargable
Alkalines for infrequenct use items would cost you a fortune compared
to regular Alkaline.

From an environmental perespective, throwing out half a dozen Alkalines
every year is insignificant compared to the amount of power and waste a

single person such as yourself uses every day.

If you want to talk environmental issues with batteries, I'm involved
in a project which has the potential to use 20 *TONS* of Alkaline
batteries for a single use! We try to push the customer towards a
rechargable solution, but they want Alkalines. The amount of guilt I
feel is incredible!
