   Battery chargers may be strictly manual, or may include controls for time and charging voltage. Battery chargers that apply a high voltage (for example, more than 14.4 volts on a 12-volt nominal system) will result in the emission of hydrogen gas from the battery, which may damage it or create an explosion risk.

   A typical 12 V, 40 Ah lead-acid car battery. An automotive battery, or car battery, is a rechargeable battery that is used to start a motor vehicle.. Its main purpose is to provide an electric current to the electric-powered starting motor, which in turn starts the chemically-powered internal combustion engine that actually propels the vehicle.

   Each radio would be issued with three batteries, and a range of battery chargers was available for this common battery. With the exception of the PRC 349 and UK RT 350 which are 12 Volt (nominal), The Manpack and Portable sets and their chargers were almost all nominally rated 24V DC ( Direct Current ) to match the British Army's choice of 24 ...

5. Trickle charging - Wikipedia

   en.wikipedia.org/wiki/Trickle_charging

   Trickle charging is the process of charging a fully charged battery at a rate equal to its self-discharge rate, enabling the battery to remain at its fully charged level. This state occurs almost exclusively when the battery is not loaded, as trickle charging will not keep a battery charged if current is being drawn by a load.

6. Lead–acid battery - Wikipedia

   The sum of the molecular masses of the reactants is 642.6 g/mole, so theoretically a cell can produce two faradays of charge (192,971 coulombs) from 642.6 g of reactants, or 83.4 ampere-hours per kilogram for a 2-volt cell (or 13.9 ampere-hours per kilogram for a 12-volt battery).

7. Porsche Taycan - Wikipedia

   en.wikipedia.org/wiki/Porsche_Taycan

   According to manufacturer estimates, the battery pack can be charged from 5% to 80% in 22.5 minutes in ideal situations, using an 800-volt DC fast charger with 270 kW (367 PS; 362 hp) of power. The Taycan is also backward compatible with existing 400-volt stations up to 150 kW (204 PS; 201 hp) using an onboard step-up converter that converts ...
