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. Solar charger - Wikipedia

   en.wikipedia.org/wiki/Solar_charger

   A solar charger is a charger that employs solar energy to supply electricity to devices or batteries. They are generally portable. Solar chargers can charge lead acid or Ni-Cd battery banks up to 48 V and hundreds of ampere hours (up to 4000 Ah) capacity. Such type of solar charger setups generally use an intelligent charge controller.

   Power Storage. Some solar chargers come with built in power storage that keeps a portion of the energy captured in a battery connected to the panels.

5. Lead–acid battery - Wikipedia

   en.wikipedia.org/wiki/Lead–acid_battery

   AGM cells already have a high acid content in an attempt to lower the water loss rate and increase standby voltage, and this brings about shorter life compared to a lead–antimony flooded battery. If the open circuit voltage of AGM cells is significantly higher than 2.093 volts, or 12.56 V for a 12 V battery, then it has a higher acid content ...

6. Sodium-ion battery - Wikipedia

   en.wikipedia.org/wiki/Sodium-ion_battery

   Sodium-ion batteries (NIBs, SIBs, or Na-ion batteries) are several types of rechargeable batteries, which use sodium ions (Na +) as their charge carriers. In some cases, its working principle and cell construction are similar to those of lithium-ion battery (LIB) types, but it replaces lithium with sodium as the intercalating ion .

7. IUoU battery charging - Wikipedia

   en.wikipedia.org/wiki/IUoU_battery_charging

   The voltages in the U and U o phases (stages 2 and 3) depend on the type of battery and the temperature. Batteries have varying numbers of cells (typically six for an automotive battery) and may be flooded-cell, absorbed-glass-matt (AGM), or gel-electrolyte types. The numbers in the table below are for a temperature around 20 °C (68 °F).
