2. 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 ...

3. Lead–acid battery - Wikipedia

   en.wikipedia.org/wiki/Lead–acid_battery

   In the 1970s, the valve-regulated lead-acid (VRLA), or sealed, battery was developed, including modern absorbed glass mat (AGM) types, allowing operation in any position. It was discovered early in 2011 that lead-acid batteries do in fact use some aspects of relativity to function, and to a lesser degree, liquid metal and molten-salt batteries ...

4. Silver–calcium battery - Wikipedia

   en.wikipedia.org/wiki/Silver–calcium_battery

   Silver-calcium batteries generally require more charging voltage (14.4 to 14.8 V) and deteriorate rapidly in vehicles which do not provide the required voltage range. ( Alternators ) which never reach required voltage range will cause rapid sulfation due to battery never being charged fully.

5. Automotive battery - Wikipedia

   en.wikipedia.org/wiki/Automotive_battery

   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.

6. Comparison of commercial battery types - Wikipedia

   en.wikipedia.org/wiki/Comparison_of_commercial...

   Under certain conditions, some battery chemistries are at risk of thermal runaway, leading to cell rupture or combustion.As thermal runaway is determined not only by cell chemistry but also cell size, cell design and charge, only the worst-case values are reflected here.

7. IUoU battery charging - Wikipedia

   en.wikipedia.org/wiki/IUoU_battery_charging

   In practice, it depends on the capability of the charger. The battery capacity C is expressed in Ah units, typically the C 20 value based on a 20-hour discharge time. [3] The charging current (in A units) can be written as C/t where t is a time. For example, for a battery with C = 40 Ah, a current C/10 is equal to 4 A. The charging current is a ...

8. Electric battery - Wikipedia

   en.wikipedia.org/wiki/Electric_battery

   The VRLA battery uses an immobilized sulfuric acid electrolyte, reducing the chance of leakage and extending shelf life. [38] VRLA batteries immobilize the electrolyte. The two types are: Gel batteries (or "gel cell") use a semi-solid electrolyte. Absorbed Glass Mat (AGM) batteries absorb the electrolyte in a special fiberglass matting.

9. Rechargeable battery - Wikipedia

   en.wikipedia.org/wiki/Rechargeable_battery

   A rechargeable battery, storage battery, or secondary cell (formally a type of energy accumulator), is a type of electrical battery which can be charged, discharged into a load, and recharged many times, as opposed to a disposable or primary battery, which is supplied fully charged and discarded after use.
