Battery Packs and Battery Pack Chargers

If you want to know what a battery pack is, you’ll discover the answer on this page. We dedicate this article to the fundamentals about battery packs (and their chargers).

First off, what is a battery pack? It’s a battery comprised up of individual battery cells inside attached/encased to form a single battery component. To illustrate this more clearly,  here’ s an example:  A 9.6 Volt battery pack, is really 8 single 1.2 Volt cells grouped together. One could say that as long as there are two or more individual cells inside a battery pack, then it is in fact a battery pack. But why do these exist? Well, many consumer electronic products are built at the factory with battery packs instead of using single cells. When these batteries need to be replaced, they need to be replaced as what they are, which is a battery pack. Sometimes, purchasing a new battery pack at the store can be as expensive as the whole product was to begin with that hold the original battery pack. So..........many people opt to build them themselves or purchase them online from a reliable battery pack supplier who can provide better pricing than can brick and mortar stores.

There are many difference size cells that can make up a battery pack. Sub C cells, AA, AAA, 2/3A, 2/3 AA and so on, can all be the inside cells used in battery packs today.

If the batteries inside the battery pack are rechargeable, then the battery pack becomes a rechargeable battery pack and can be used in a battery pack designated charger, to replenish their power.

Cordless telephones use battery packs, computers can have battery packs and many other products we all use each day. Until you actually open the battery compartment of a device, you might not be aware that there’s a battery PACK inside it!

Of course, a rechargeable battery pack needs a battery pack charger to go with it to preserve the intended life cycles of the battery pack.

For your information, we provide a little chart of the most commonly sized battery packs around.

2.4 volt: to help you understand, this size pack would require 2 cells of 1.2 volt each

Then there are: 4.8 volt, 6 volt, 7.2 volt,  8.4 volt 9.6 volt 12 volt,  24 volt, and 36 volt battery packs.

The above packs are available for NiCD (Nickel Cadmium) or NIMH (Nickel Metal Hydride) battery chemistry.

3.7 volt: 1 Lithium Ion (Li-Ion) cell (Re: Lithium-Ion, there are also: 7.4 Volt Lithium ion Battery Packs, and 11.1 Volt Lithium Ion  Battery Packs
