#2 D BATTERIES SERIES#

Imagine the batteries shown in the diagram are rated at 1.5 volts and 500 milliamp-hours. Most AAA, AA, C and D batteries are around 1.5 volts. In a battery, voltage determines how strongly electrons are pushed through a circuit, much like pressure determines how strongly water is pushed through a hose. Voltage is a measure of energy per unit charge and is measured in volts.

The four batteries in series will together produce the current of one cell, but the voltage they supply will be four times that of a single cell.

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

The diagram shows these two arrangements. You normally group them together in a serial arrangement to increase the voltage or in a parallel arrangement to increase current.

Weight without Batteries: 3.986 oz.In many devices that use batteries - such as portable radios and flashlights - you don't use just one cell at a time.

Brightness Outputs: 35 lumens - 113 hours.Peak Beam Distance: 45 meters (147.64 ft.).Single-output design for effortless utilization.Convenient hanging ring allows for effortless carrying in-between uses.Polypropylene body is chemical-resistant, which prevents corrosion and wear.Non-conductive materials allow for use in sensitive construction job sites.This 2D LED flashlight, which is powered by two D batteries (sold separately) is perfect for those requiring a no-fuss, no-frills single-output light. Finally, the Energizer Industrial 1251L is equipped with a hanging ring on its tail-cap for effortless transport and carrying. The bright yellow light is not only resistant to 1-meter drops and splashes of water, but it is also easy to find, due to its color. The Energizer Industrial 1251L is constructed from polypropylene and other non-conductive materials, therefore making it extremely durable, long-lasting, and therefore perfect for use on a job site or in a construction zone. This 2D LED flashlight, from Energizer, is a simple single-output light with a one-button interface. There are also no Strobe or SOS functions to accidentally activate. There is no need for double and triple taps of the side switch in order to operate the light. This hand-held light features a single output mode of 35 lumens, which makes it incredibly easy to use and beneficial in a variety of settings. The Energizer Industrial 1251L 2D LED flashlight is a simple yet useful illumination tool.
