rechargeable

There are rechargeable alkalines that provide 1.5V but they are very unreliable and the rest of the rechargeable AA market is lower voltage.

Except they forgot to mention that some types of rechargeable batteries get damaged if you discharge them completely.

Idea: make a chess clock where the two sides are independently powered by rechargeable batteries that start with low charge.

Perhaps a bit of a novelty given the rechargeable battery argument others have mentioned.

What I don't get: I stopped using alkalines long ago, and have since settled for Eneloop rechargeable batteries.

I think its fair to compare onsie-twosie rechargeables to bulk disposables; isn't that the entire point of being rechargeable?

Solar lights and rechargeable flashlights cost about US$6 to US$10 at retail today, which is a significant amount of money to a lot of people.

Oh and the pen takes 2 batteries - one for the stylus and one watch battery for the button - neither of which are rechargeable.

So I need to keep that clock powered up for more than a decade to run a profit on the rechargeable.

Also, it doesn't help that the cheapest rechargeable batteries and chargers lead to a comparatively bad user experience (batteries not holding a charge long, low lifetimes).

>There's no reasons you can't put a voltage boost circuit into a device It will kill rechargeable lithium batteries.

The article briefly mentions using them with rechargeable batteries.

On the other hand, making it rechargeable would allow for a pile of "charge card" puns.

He has an entire team of people who read reviews on Amazon, looking for moments when people say, "I wish this speaker were rechargeable." Pikarski then makes a rechargeable version.

It has to pass thru zero otherwise we call it a "rechargeable battery".

> "Roohparvar says the sleeve will also work with 1.2 volt rechargeable batteries, boosting them up to 1.5 volts."

Rechargeable batteries are larger and less efficient than the equivalent non-rechargeable battery, and you then need some circuitry and mechanism to charge them.

Rechargeable batteries can be reused, but still need to be replaced; this may prove lower maintenance, which means once you can get it, you are more secure with it with a less secure distribution system.
