How long will your Dyson 215681 vacuum battery last?
Please note that there are two main factors that govern how long a cordless vacuum cleaner battery will last: runtime and charge-discharge cycles.
Runtime is a measure of how much time can elapse before a fully charged battery reaches a charge of 0%. Technically a battery never reaches a 0% charge but a low charge does not permit enough power to be transmitted to the device.
Runtime is controlled by capacity and usage. Capacity is measured in Amp hours or milliamp hours. Battery capacity quantifies the total amount of energy stored within a battery. More capacity equals longer runtime between Dyson Battery 6-CELL(215681) Battery Pack charges. Hence if you want a Dyson battery to last the longest possible be sure to buy a battery with the highest possible capacity.
Runtime is also increased or decreased by usage.
All Dyson cleaner batteries slowly drain regardless if you are using it in your device or not! Once charged an electron flow occurs in a battery and once begun the electron flow will continue until the chemical is exhausted.
Chemical depletion occurs with every charge-discharge cycle. What is actually occurring during this charge-discharge cycle is replenishing spent electrons. In batteries electricity is created by charging two chemicals in a solution. This is done by applying an electrical flow to the battery’s lithium.
Charging lithium can be thought of as the introduction of ions or movement of chemistry. To move the lithium chemistry (lithium-ion, lithium polymer, lithium iron phosphate, etc) you have to have a minimum voltage applied to the lithium. Most battery cells are charged to 4.2 volts with relative safe workings at about 3.8 volts. Anything less than 3.3 volts will not be enough to charge or move the chemistry. Volts are an algorithmic measurement of current. So in a sense to create current through your Dyson SV10 battery you have to introduce current into your battery’s lithium .
