2. 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 ...

3. 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 ...

5. 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 ...

6. 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.

7. Depth of discharge - Wikipedia

   en.wikipedia.org/wiki/Depth_of_discharge

   Depth of discharge (DoD) is an important parameter appearing in the context of rechargeable battery operation. Two non-identical definitions can be found in commercial and scientific sources. The depth of discharge is defined as: the maximum fraction of a battery's capacity (given in Ah) which is removed from the charged battery on a regular basis.
