Deep Cycle Battery | 12V 120AH | Sealed | Maintenance-free | Dimension: 407x174x210x233mm
Prostar best 12v 120ah deep cycle battery is a lead battery designed to provide sustained power over a long period and run reliably until it is 80% discharged or more, at which point it needs to be recharged. It is important to note that although deep cycle batteries can be discharged up to 80%, strongly recommend not discharging below 45% to extend the life of the battery.
Maintenance free sealed 12v 120ah deep cycle battery is an inverse correlation between the depth of discharge (DOD) of the battery and the number of charge and discharge cycles it can perform; with an average “depth of discharge” of around 50% suggested as the best for storage vs cost.
Sealed 12v 100ah deep cycle battery is the battery that user can charge and discharge again and again without posing much damage to the cells of the battery. Deep Cycle Batteries are the vital part in different types of renewable energy systems, which require electricity to be stored for future use.
Deep Cycle (high-density active material and thick plates) design & special 4BS lead paste technology prolongs the cycle service life.
Radial grid design & tight assembly technology ensures an excellent high-rate discharge performance.
Unique grid alloys & special positive/negative lead paste formulations makes the battery perform excellent in deep cycle using and recover quickly upon over discharging and extend the float service life.
Using high purity raw materials ensures the battery has less self-discharge.
Gas Recombination technology ensures the battery high seal reacting rate, which can prevent the acid fog from separating out.
Efficient venting system automatically release excess gas when the pressure rises above the normal level & reseals the valves when it returns to the normal rate, which can protect the battery from bursting.
