This is an Amptek 24V 28Ah SMF Battery (Lead-acid Battery). This lead-acid battery is especially for Ebike, Solar panels. street light, inverter, etc.
what is a Lead-acid battery?
The lead-acid battery is a type of rechargeable battery.ad–acid batteries are widely used even when surge current is not important and other designs could provide higher energy densities
the chemical energy of the battery is stored in the potential difference between the pure lead on the negative side and the PbO2 on the positive side, plus the aqueous sulfuric acid. The electrical energy produced by a discharging lead–acid battery can be attributed to the energy released when the strong chemical bonds of water (H2O) molecules are formed from H+ ions of the acid and O2− ions of PbO2. Conversely, during charging, the battery acts as a water-splitting device. Accordingly, the chemical-energy content of the battery increases with the proton (i.e. acid) concentration.
