Make sure to get the standard capacity Amazon Basic," the reviewer warns, noting anecdotally that the high capacity version "will start to fail if left on a trickle charger 24/7." Amazon Basics ...
Whether a charger can charge the battery depends largely on the dimensions of the battery and internal chemistry (I.E., disposable batteries cannot be charged). Testing a nine-volt battery can be done using a multi-meter by probing the voltage across the two terminals.
A battery's capacity depends upon its cell chemistry and current draw. Duracell brand rates its alkaline D cell performance as approximately 20,000 mAh at 25 mA draw, but about 10,000 mAh at 500 mA draw. [5] This effect is generally less pronounced in cells with NiMH chemistry and hardly at all with NiCd. Many commonly available size D ...

Credit card companies don't work for free. Every time you use one, the store you're buying from is charged a "swipe fee" — and that charge will get passed down to you in higher prices.
The N-cell battery was designed by Burgess Battery Company and was part of a series of smaller batteries including the Z battery and the Number 7 battery ().. A zinc–carbon battery in this type is designated as R1 by IEC standards; likewise, an alkaline battery in this type is designated as LR1.
