Connecting two 12-volt batteries in series adds their individual voltages together to create a 24-volt battery pack. The series arrangement does not increase the capacity of the batteries.Continue Reading
Connecting the positive battery post to the negative post of a second battery and then connecting the leads of the load to the remaining two battery posts results in a series connection. This is the arrangement used in most flashlights, where the batteries stack on top of one another. Connecting a series battery pack to a device designed to operate on a single battery often burns out motors and sensitive electronic parts.
Connecting batteries in parallel increases the capacity of the batteries without increasing the voltage. The parallel connection indicates the positive post and negative post of one battery connect to their corresponding post on the second one. The load then connects to the posts of one battery. A parallel battery pack allows the load to operate twice as long. Doubling both voltage and capacity of a battery pack requires connecting two two-cell series battery packs together in parallel.
Regardless of how batteries connect, it is essential to match their type and capacity. Differences in battery chemistry result in differences in battery voltage. These differences in capacity cause one battery to drain the second below the normal level. As a result, the over-drained battery is often unable to recover from the deep discharge, shortening its life.Learn more about Electrical
After wiring all of the solar panels together to combine the amps and voltages, connect the panels to a charge controller, deep-cycle batteries and an AC inverter, then run the AC inverter to the main electric box. Most appliances within a building use alternating current, so the direct current coming from the solar panels needs to be converted before it can be used.Full Answer >
Some tips for wiring 240 volt outlets include obtaining the necessary permits, using a circuit breaker of 240 volts, using a deep and wide outlet box, connecting the ground wire, and grounding a metal outlet box. Also, use the appropriate cables for appliances that use 120 and 240 volts and those that use only 240 volts, and do not use the cable's neutral wire when outlets with three poles are used.Full Answer >
Depending on composition, AA batteries put out 1.1 to 3.6 volts of electricity during a discharge and contain between 590 and 2,100 amp hours. The major types of AA battery are lithium ion, nickel-cadmium, NiMH, carbon-zinc and Alkaline long life.Full Answer >
A fresh, single AA battery supplies between 1.2 to 1.65 volts, depending on its composition. Nickel-metal hydride and nickel cadmium batteries put out 1.2 volts and are rechargeable. Lithium, zinc-carbon and alkaline batteries put out 1.5 volts but are not rechargeable. Nickel-zinc batteries put out 1.65 volts.Full Answer >
