In many devices that use hp spare battery 484170-001 -- such as portable radios and flashlights -- you don't use only one cell at any given time. You normally group them together inside a serial arrangement to improve the voltage or perhaps in a parallel arrangement to improve current. The diagram shows both of these arrangements.

Top of the diagram shows a parallel arrangement. The four batteries in parallel will together produce the voltage of 1 cell, however the current they supply will be 4 times that of a single cell. Current may be the rate at which electric charge passes through a circuit, and it is measured in amperes. Batteries are rated in amp-hours, or, in the case of smaller household batteries, milliamp-hours (mAH). An average household cell with a rating of 500 milliamp-hours will be able to supply 500 milliamps of current towards the load for just one hour. You can slice and dice the milliamp-hour rating in lots of various ways. A 500 milliamp-hour hp spare battery 484170-001 could also produce 5 milliamps for 100 hours, 10 milliamps for 50 hours, or, theoretically, 1,000 milliamps for 30 minutes. Generally speaking, batteries with higher amp-hour ratings have greater capacities.

The low diagram depicts a serial arrangement. The four batteries in series will together make the current of one cell, but the voltage they provide is going to be four times what single cell. Voltage is a way of measuring energy per unit charge and is measured in volts. In a hp spare battery 484170-001, voltage determines how strongly electrons are pushed via a circuit, much like pressure determines how strongly water is pushed through a hose. Most AAA, AA, C and D batteries are around 1.5 volts.

Imagine the batteries shown in the diagram are rated at 1.5 volts and 500 milliamp-hours. The four batteries in parallel arrangement will produce 1.5 volts at 2,000 milliamp-hours. The four batteries arranged in a series will produce 6 volts at 500 milliamp-hours.

hp spare battery 484170-001 technologies have advanced dramatically since the times of the Voltaic pile. These developments are clearly reflected within our  484170-001 often be Recovered , portable world, which is more dependent than ever before on the portable source of energy that batteries provide. One can only imagine exactly what the next generation of smaller, stronger and longer-lasting batteries will bring.
