What is a "Deep-Cycle" Battery?
A deep-cycle battery is a lead-acid battery designed to be regularly deeply discharged using most of its capacity. Deep-cycle batteries are designed to discharge up to 80% (DOD) of its capacity, depending on the manufacturer’s specifications and the construction. Some deep-cycle batteries can be discharged up to a 100% (DOD). These batteries are typically been used for solar / off grid applications, server rooms (UPS), telecommunications, backup power etc. . .
What is an "AGM" Battery?
AGM is an acronym, for "Absorbed Glass Mat". These batteries feature a white fiberglass mesh between the battery plates which serves to contain the electrolyte. They are also known as "Dry Cell Batteries”, “Waterless Batteries”, “Gell Batteries”, “Lead Crystal Batteries”, or “Telkom Batteries”.
AGM Batteries differ from flooded lead acid batteries as that the electrolyte is held in the glass mats, as opposed to freely flooding the plates. Very thin glass fibbers are woven into a mat to increase surface area enough to hold sufficient electrolyte on the cells for their lifetime.
AGM Batteries can deep-cycle and they charge up to three times faster than conventional batteries.
AGM Batteries are ideally for solar / off grid applications due their long lasting and deep-cycle capabilities.
What is a "Starting" Battery?
A Starting battery is a battery that is designed to deliver short bursts of high-current electrical power for
cranking (starting) an engine.
Thus frequently discharging only a small portion of its capacity. These types of batteries needs constant charging, especially after starting a vehicle!
What is a "Stop/Start" Battery?
Stop/Start batteries are designed for vehicles that turns of its engine when the vehicle stop, i.e. at a robot.
Stop/Start batteries remains fully charge for a longer period. Yet, it’s not a deep cycle battery. These batteries can produce a lot of short bursts of high-current, electrical power to restart an engine while stopping within minutes from each other. Under normal circumstances, a normal lead-acid battery will overheat, which could dramatically shorten its service life as it will build up resistance..
