Victron Energy BAT412550084 - 12V/60Ah AGM Deep Cycle Battery
Deep Cycle AGM batteries
Victron deep cycle 12V AGM batteries
VRLA technology
VRLA is the English abbreviation for Valve Regulated Lead Acid, i.e. the battery cells are valve-controlled and overcharged or a cell error gas can escape through a safety valve. VRLA batteries have excellent leak resistance and can be used in any orientation. They are absolutely maintenance-free.
Sealed (VRLA) AGM batteries
AGM stands for Absorbent Glass Mat. With this type of battery, the electrolyte is absorbed by capillary action in a fleece made of fine glass fibers. In our book "Always Power" we have pointed out that AGM batteries are primarily suitable for short-term high current requirements (engine start).
Low self-discharge
Victron VRLA batteries can last for a long time because of the use of lead-calcium grids and high-purity materials be stored for periods without intermediate charging. The self-discharge rate is less than 2% per month at 20°C. It doubles for every 10°C rise in temperature. When stored in a cool place, Victron VRLA batteries can be stored for up to a year without being recharged.
Excellent behavior after deep discharge
Victron VRLA batteries have excellent recovery behavior even after prolonged deep discharge. However, it must be pointed out that frequent and prolonged deep discharges can also lead to irreversible damage to Victron batteries.
Discharging behavior of the battery
The nominal capacity of the Victron batteries refers to a discharge time of 20 hours i.e. H. to a discharge current of 0.1 C. A lower discharge current increases the effective capacity, and conversely it decreases with a higher discharge current (see table in data sheet). The AGM series from Victron is characterized by excellent behavior at high discharge currents.
