2. Batteries in space - Wikipedia

   en.wikipedia.org/wiki/Batteries_in_space

   Vehicles such as the Apollo spacecraft and the Space Shuttle required more power than could be supplied by batteries or solar panels, and so relied on hydrogen fuel cells to provide several kilowatts of power for hundreds of hours. [2] A reserve battery is a primary battery that keeps its chemical reactants separated until needed. This improves ...

3. Deep-cycle battery - Wikipedia

   en.wikipedia.org/wiki/Deep-cycle_battery

   A deep-cycle battery powering a traffic signal. A deep-cycle battery is a battery designed to be regularly deeply discharged using most of its capacity. The term is traditionally mainly used for lead–acid batteries in the same form factor as automotive batteries; and contrasted with starter or cranking automotive batteries designed to deliver only a small part of their capacity in a short ...

   The battery charge/discharge units (BCDUs) regulate the amount of charge put into the battery. Each BCDU can regulate discharge current from two battery ORUs (each with 38 series-connected Ni-H 2 cells), and can provide up to 6.6 kW to the Space Station. During insolation, the BCDU provides charge current to the batteries and controls the ...

   For example, a 250 CCA battery will have more starting power than a 250 CA (or MCA) one, and likewise a 250 CA will have more than a 250 HCA one. [26] Cranking amperes (CA): the amount of current a battery can provide at 32 °F (0 °C), again for 30 seconds at a voltage equal to, or greater than, 7.2 volts.

6. VRLA battery - Wikipedia

   en.wikipedia.org/wiki/VRLA_battery

   A 12V VRLA battery, typically used in small uninterruptible power supplies and emergency lamps.. A valve regulated lead‐acid (VRLA) battery, commonly known as a sealed lead-acid (SLA) battery, [1] is a type of lead-acid battery characterized by a limited amount of electrolyte ("starved" electrolyte) absorbed in a plate separator or formed into a gel, proportioning of the negative and ...

7. Lead–acid battery - Wikipedia

   en.wikipedia.org/wiki/Lead–acid_battery

   [17] [18] Specific values for a given battery depend on the design and manufacturer recommendations, and are usually given at a baseline temperature of 20 °C (68 °F), requiring adjustment for ambient conditions. IEEE Standard 485-2020 (first published in 1997) is the industry's recommended practice for sizing lead–acid batteries in ...
