Cost-based pricing is applied through setting the price of a product or good based on its production and delivery cost with a certain target margin. This method shows an emphasis for cost recovery and profit maximisation which tends to result in lower prices in commodities and/or lower quality of goods. [3]
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.
Cell balancing in a 5-cell battery, where the fifth cell has a lower capacity. Legend: A , Case where cells are unbalanced; B , Case where cells 3 and 5 and significantly discharged; C , Case where cells 2 and 5 and significantly over-charged; D , Case where battery is being charged with a passive balancer working on cells 2 and 5.
A common application for charge-pump circuits is in RS-232 level shifters, where they are used to derive positive and negative voltages (often +10 V and −10 V) from a single 5 V or 3 V power supply rail. Charge pumps can also be used as LCD or white-LED drivers, generating high bias voltages from a single low-voltage supply, such as a battery.
Quick Charge (QC) is a proprietary battery charging protocol developed by Qualcomm, used for managing power delivered over USB, mainly by communicating to the power supply and negotiating a voltage. Quick Charge is supported by devices such as mobile phones which run on Qualcomm system-on-chip (SoCs), and by some chargers; both device and ...

Nickel–zinc batteries have a charge–discharge curve similar to 1.2 V NiCd or NiMH cells, but with a higher 1.6 V nominal voltage. [5]Nickel–zinc batteries perform well in high-drain applications, and may have the potential to replace lead–acid batteries because of their higher energy-to-mass ratio and higher power-to-mass ratio – as little as 25% of the mass for the same power.

Float voltage is the voltage at which a battery is maintained after being fully charged to maintain that capacity by compensating for self-discharge of the battery. [1] The voltage could be held constant for the entire duration of the cell's operation (such as in an automotive battery) or could be held for a particular phase of charging by the charger. [2]
