In the 1970s, actor Robert Conrad was the spokesman for Eveready Alkaline Power Cells, in which he compared his tough physique to the performance of the battery placed on his shoulder, and daring someone to knock it off. In the early 1980s, it utilized the slogan, "Energized, for life!", showing people using Energizers in everyday situations.
It can use nearly all of the energy in a single-cell electric battery, even far below the voltage where other circuits consider the battery fully discharged (or "dead"); hence the name, which suggests the notion that the circuit is stealing energy or "joules" from the source – the term is a pun on "jewel thief".

The Headset Profile (HSP) connects headphones and earbuds to a cell phone or laptop. The Health Device Profile (HDP) can connect a cell phone to a digital thermometer or heart rate detector. The Video Distribution Profile (VDP) sends a video stream from a video camera to a TV screen or a recording device.
Example charging graph. On the left: per-cell quantities. On the right: example values for a 40 Ah, 6-cell (12 V) battery. Note: schematic illustration; not based on actual measurements. IUoU is a DIN-designation [1] (DIN 41773) for a lead-acid battery charging procedure that is also known as 3-stage charging, 3-phase charging, or 3-step charging.
The maximum point-blank range of a firearm will depend on a variety of factors such as muzzle velocity and the size of the target. [3] In popular usage, point-blank range has come to mean extremely close range with a firearm, yet not close enough to be a contact shot. [4]
A simple charger typically does not alter its output based on charging time or the charge on the battery. This simplicity means that a simple charger is inexpensive, but there are tradeoffs. Typically, a carefully designed simple charger takes longer to charge a battery because it is set to use a lower (i.e., safer) charging rate.
Normal operation of a pre-charge circuit is to terminate pre-charge mode when the circuit voltage is 90% or 95% of the operating voltage. Upon completion of pre-charging, the pre-charge resistance is switched out of the power supply circuit and returns to a low impedance power source for normal mode.
