[11] [12] [13] Battery-operated electric razors have been available using rechargeable batteries sealed inside the razor's case, previously nickel cadmium or, more recently, nickel metal hydride. Some modern shavers use Lithium-ion batteries (which do not suffer from memory effect). Sealed battery shavers either have built-in or external ...
Philips Norelco is the American brand name for electric shavers and other personal care products made by the Consumer Lifestyle division of Philips. [ 1 ] [ 2 ] For personal care products marketed outside the United States, Palau, Micronesia, and the Marshall Islands, Philips used the Philishave trademark until 2006.
Philips is now co-branding their shavers sold in the US as "Philips Norelco" in preparation of a phase-out of the Norelco name. Philips have celebrated their 80th anniversary in the electric shaver business by marketing special 'Heritage Edition' shaver models reviving the Philishave brand.
Battery balancing and battery redistribution refer to techniques that improve the available capacity of a battery pack with multiple cells (usually in series) and increase each cell's longevity. [1] A battery balancer or battery regulator is an electrical device in a battery pack that performs battery balancing. [ 2 ]
A battery management system (BMS) is any electronic system that manages a rechargeable battery (cell or battery pack) by facilitating the safe usage and a long life of the battery in practical scenarios while monitoring and estimating its various states (such as state of health and state of charge), [1] calculating secondary data, reporting that data, controlling its environment ...
Inductive charging is not considered a mature dynamic charging technology as it delivers the least power of the three electric road technologies, its receivers lose 20%-25% of the supplied power when installed on trucks, and its health effects have yet to be documented, according to a French government working group on electric roads.

The actual voltage, matching the car battery's voltage, will be approximately 12.5 volts when dormant (less in cold conditions), approximately 14.5 volts when the engine and the alternator/generator are operating (more when cold), and may briefly drop as low as 5–6 volts during engine start due to the high temporary battery current usage.

Technically: it is the "thermal propagation" properties of the battery pack which may, or may not, prevent it from getting involved in an automotive fire – even if one or more of the cells in the battery pack has overheated dangerously, the upholstery has already caught on fire, or the car's wiring harness is severely damaged.
