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 ...

   en.wikipedia.org/wiki/IUoU_battery_charging

   Example charging graph. On the left: per-cell quantities. On the right: example values for a 40 Ah, 6-cell (12 V) battery. Note: schematic illustration; not based on actual measurements. IUoU is a DIN-designation [1] (DIN 41773) for a lead-acid battery charging procedure that is also known as 3-stage charging, 3-phase charging, or 3-step charging.

4. Lead–acid battery - Wikipedia

   en.wikipedia.org/wiki/Lead–acid_battery

   To reduce the water loss rate, calcium is alloyed with the plates; however, gas build-up remains a problem when the battery is deeply or rapidly charged or discharged. To prevent over-pressurization of the battery casing, AGM batteries include a one-way blow-off valve, and are often known as valve-regulated lead–acid (VRLA) designs.

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.

   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.

   Here's what some of the latest EV charging vs. gasoline data found: Charging an EV is cheaper than filling up with gas in all 50 states, according to The Washington Post.

9. 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.
