You take copper(like a penny), Zinc (like a Nail). Then u stick them in a potato and touch either the negative or positive end to either one and it should power what ever you need to power.
you take a patato put a zink nail in it then put a penny in it put bolth leads on a light or something it will power it butyou might have to have a huge patato
The Accu-Chek Active glucose meter typically uses two 3-volt lithium coin cell batteries, CR2032. It is important to ensure you use the correct batteries to maintain accurate performance of the meter.
A 3 volt battery is a type of battery that produces a voltage of 3 volts. It is commonly used in various electronic devices such as remote controls, toys, and small gadgets. The most common types of 3 volt batteries are coin cell batteries and AAA or AA batteries.
NiMH batteries must be charged first. The charge won't last as long as an alkaline battery but they can be recharged 100's of times. They have a slightly lower voltage (1.2 instead of 1.5) and should work fine in many devices. For an electronic device, you may see a low battery indicator because of the lower voltage.
Energizer (and many other battery companies) sell two kinds of "lithium" batteries: "Lithium Photo/Coin", Li-Mn, "CR" button cells, such as the CR2032, provide about 3 V. "Lithium cylindrical", "Lithium-iron", "Li/Fe", which comes in AA and AAA, are about 1.5 V, and also comes as those rectangular 9V batteries, which... of course... are about 9V.
The answer is governed by the size of the flashlight. Count the amount of batteries that go into the flashlight and then multiply by 1.5 and this will give you the voltage of the flashlight. For NiCd and NiMH rechargeable batteries multiply by 1.3 volts.
Any lithium coin batter
Coin batteries are better than AAA batteries because they have lithium. Lithium brings the best out of the battery and holds the most amount of energy compared to AAA batteries.
car batteries
Frozen batteries last longer unfrozen batteries.
the sunlight hits the batteries and powers them :)
How do the cars solar collectors work together with the batteries?
It won't work because the polarity of the batteries is reversed.
Get a coin preferably a penny or cent depending where you live unscrew the bolt were the batteries are kept put the new ones in + side down rescrew the bolt push the button on the keyboard and it should work a treat I have an iMac myself.

Batteries only store a certain amount of electricity, then they are depleted and no longer work.
Since Batteries work on DC then it doesnt matter wheter or not they are European or American, as long as you choose the right Voltage and Current for the batteries.
