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 ...

   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 ...

   This battery, introduced in 1901, was very common in continental Europe until the 1970s. It usually contains three B cells in series. In Switzerland as of 2008, 4.5-volt batteries account for only 1% of primary battery sales.

6. Lead–acid battery - Wikipedia

   en.wikipedia.org/wiki/Lead–acid_battery

   IUoU battery charging is a three-stage charging procedure for lead-acid batteries. A lead-acid battery's nominal voltage is 2.2 V for each cell. For a single cell, the voltage can range from 1.8 V loaded at full discharge, to 2.10 V in an open circuit at full charge.

   For a lead–acid battery is typically between 1.1 and 1.3. For different lead–acid rechargeable battery technologies it generally ranges from 1.05 to 1.15 for VRSLAB AGM batteries, from 1.1 to 1.25 for gel, and from 1.2 to 1.6 for flooded batteries. The Peukert constant varies with the age of the battery, generally increasing (getting worse ...

9. Electric battery - Wikipedia

   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.
