There are three primary battery types available for consumer use. They are alkaline, nickel metal hydride (NIMH), and lithium ion. Each type has its pros and cons. Each one also has a distinctive place in technology history.
Can you use D batteries instead of C?
The D cell batteries can give more current than the C batteries. If you needs lots of current and try to get it from a tiny battery, it won't work as well. As for adding them together, you'll notice that in most electronics, you put them in so that the positive end of one touched the negative of the other.
What do D batteries look like?
What does a D size battery look like? Typically, they are squat and solid, with a barrel-like shape. The positive contact point or terminal on the top of each battery has a distinct metal cap shape. D batteries were first invented in 1898.
What do the numbers on rechargeable batteries mean?

Same diameter as AA battery, used in small electronics, including pulse oximeters, as well as use in some computer models (such as most pre-Intel Macintosh models and some older IBM PC compatibles) as the CMOS battery.
What is the nomenclature of a battery?
The complete nomenclature for a battery specifies size, chemistry, terminal arrangement, and special characteristics. The same physically interchangeable cell size or battery size may have widely different characteristics; physical interchangeability is not the sole factor in substituting a battery.
What is a cell with a nub on the terminal called?
Cylindrical cells typically have a positive terminal nub at one end, and a flat negative terminal at the other. A cell with a nub on the positive terminal is called a button-top, and a cell without a positive nub is called a flat-top. Two different cells of the same nominal size, e.g. two 18650 cells, may have different diameter buttons if made by different manufacturers, and this can lead to incompatibility with devices. Flat-top cells cannot be used in series without modification or soldering into position, because the flat positive terminal of one cell cannot contact with the next cell's negative terminal. Rarely, however, a manufacturer may include tiny bumps on the negative terminal, so flat-tops can be used in series.
How long is a lithium ion battery?
Many are also available with internal protection circuits that can increase their physical length; for example, an 18650 is around 65 mm (2.56 in) long, but may be around 68 mm (2.68 in) long with an internal protection circuit. Some such circuits increase cell diameter instead. The increased dimensions may mean the cell will no longer fit in battery compartments intended for cells without such circuitry.
What does the IEC designation number mean?
IEC designation numbers indicate the physical dimensions of the cylindrical cell. Cells less than one centimeter in height are assigned 4-digit numbers, where the first 2 digits are the diameter in millimeters, while the last 2 digits are the height in tenths of millimeters.
What is a PP battery?
The PP ( Power Pack) series was manufactured by Ever Ready in the UK ( Eveready in the US). The series comprised multi-cell carbon-zinc batteries used for portable electronic devices. Most sizes are uncommon today; however, the PP3 size (and to a lesser extent PP8 and PP9, which are used in electric fencing and marine applications respectively) is readily available. The PP4 was cylindrical; all the other types were rectangular. Most had snap terminals as seen on the common PP3 type. These came in two incompatible sizes, as is evident in some of the pictures below, those on larger, mostly older, battery types such as the PP9 being somewhat larger than those on the smaller batteries such as the PP3.
What does the increased dimensions mean in a cell?
The increased dimensions may mean the cell will no longer fit in battery compartments intended for cells without such circuitry. Commonly-used designation numbers indicate the physical dimensions of the cylindrical cell, as given in IEC standard 60086-1 for cylindrical primary cells.
What is the best source of information to find the recommended battery group size and specifications?
The best source of information to find the recommended battery group size and specifications is your Owner’s Manual.

How to clean battery terminals?
How do you clean battery terminals and contacts? 1 Remove the battery cables and inspect them. 2 Spray the battery cleaner on the terminals. You can also mix up one tablespoon of baking soda to one cup of water and apply it to the terminals. 3 Scrub the terminals with an old toothbrush or wire brush that is made for this purpose. Scrub until all of the buildup is removed. 4 Rinse off the residue with plain water and allow the terminals to completely dry. 5 Reconnect the battery cables.
How many times can a rechargeable battery be used?
Rechargeable batteries can be recharged and reused from 500 to 1000 times depending on usage. The different battery technologies affect the performance of the batteries. There are 3 main types of rechargeable batteries: NiCd (Nickel-Cadmium) NiMH (Nickel-Metal Hydride) Li-ion (Lithium Ion)
What is the capacity of a battery?
Capacity is the amount of electrical charge stored inside the battery. The more charge there is in a battery, the more electrical current it can deliver and the longer it can power your device. For AA rechargeable batteries, you’ll find capacities between 1,300mAh and 2,900mAh AAA rechargeable batteries range from 500mAh to 1,100mAh.
How does a stay charged battery work?
Stay-charged reachargeable batteries hold their charge much more effectively when not in use. Standard NiMH rechargeable batteries (those that do not have the Stay-Charged technology) will gradually lose their power over a period of weeks and months even when not in use (around 30% per month) in a process known as ‘self-discharge’. This occurs when the internal chemical reactions reduce the stored charge of the battery even when the battery is not in use. By comparison, stay-charged batteries have a low self-discharge rate of around 2-3% per month, therefore retaining their charge and remaining ready to use.
Why are NiCd batteries so cheap?
NiCd (Nickel-Cadmium) NiCd is now the older technology, these batteries are fairly cheap because they suffer "memory" problems. The golden rule with NiCds is to completely discharge them every time before charging them again, that way they will always be at their best performamce.
What does "stay charge" mean on a rechargeable battery?
If your device requires batteries which hold their charge in between uses and perhaps are not used for a period of time you may wish to choose a rechargeable battery with stay-charge technology which means the batteries retain their charge between uses. H. Temperature VS. Battery Life.
Why does self discharge cause less than a full charge?
Self-discharge decreases the shelf-life of batteries and causes them to initially have less than a full charge when actually put to use. The rate at which self-discharge in a battery occurs is dependent on a range of factors such as the type of battery, state of charge, charging current and ambient temperature.
What temperature should a battery be charged at?
Most battery manufacturers will recommend the ideal operating temperature of their products to be at or around room temperature, around 68°-80°F. Operating or charging your battery at different temperatures outside this range will result in very difference performance from the same battery. Interestingly, there you can see a big difference in operation between a battery operated at low temperatures vs. the same battery operated at high temperatures
How many digits are in a lithium battery?
Cylindrical lithium-ion battery cells are usually represented by five digits. From the left, the first and second digits refer to the cell diameter, the third and fourth digits refer to the battery height, and the fifth digit refers to the circle.
