Victron AGM Battery 12V/240Ah

Victron AGM Battery 12V/240Ah

Victron AGM Battery 12V/240Ah For consumer battery banks on yachts, in vehicles, and in off-grid systems used cyclically daily, and for emergency power installations in trickle charging. AGM delivers high short-term currents better than gel, which is suitable for inverters and winches. The battery is sealed and completely maintenance-free; topping up is neither necessary nor possible. Battery voltage and charging voltages Nominal 12 V. During normal cyclic use, the absorption voltage is 14.2–14.6 V, for fast recharging 14.6–14.9 V. Trickle 13.5–13.8 V and storage 13.2–13.5 V. The charging current preferably remains below 0.2 C, for this battery 48 A. Above this, the battery temperature rises by more than 10 °C and temperature compensation is required. Capacity at high discharge current The 240 Ah applies to a 20-hour discharge (0.05 C) down to 10.8 V at 25 °C. At higher currents, the available capacity decreases: 85% after 5 hours of discharge, 65% after 1 hour, and 42% after 15 minutes. With a constant power load, such as an inverter, the capacity decreases more rapidly. The maximum current for 5 seconds is 8 C. Connectable with * Chargers with a 3-stage charging curve (bulk, absorption, trickle) or with Victron’s adaptive 4-stage charging curve * The 4-stage charging curve limits gassing (Battery Safe Mode), adjusts the absorption time, and reduces the voltage during the storage phase * A battery monitor for tracking the charge status Composition Flat-plate AGM: the electrolyte is absorbed by capillary action into a fiberglass mat between the plates. The lead-calcium grids and pure materials keep self-discharge below 2% per month at 20°C. Self-discharge doubles for every 10°C increase in temperature. Construction VRLA construction: the battery is sealed and gas escapes only through the safety valves in the event of overcharging or a cell defect. Copper connections. Dimensions 522 x 240 x 224 mm (lxwxh), weight 67 kg. Installation * High temperature shortens the lifespan in trickle charging: 7–10 years at 20°C, 4 years at 30°C and 2 years at 40°C * At low temperature, capacity decreases significantly; choose a cool, but not cold, location * Use hoisting or lifting aids due to the weight of 67 kg Question & Answer QuestionAnswerWhich absorption voltage do I set on the charger?14.2–14.6 V for normal cyclic use and 14.6–14.9 V for fast recharging. Trickle charge 13.5–13.8 V. What temperature compensation applies to this battery? -24 mV/°C for a 12 V battery, with 25 °C as the midpoint. Necessary if the battery is colder than 10 °C or warmer than 30 °C for an extended period. Does temperature affect capacity and lifespan? Yes. At low temperatures, capacity drops sharply. At high temperatures, trickle charge lifespan decreases from 7–10 years at 20 °C to 2 years at 40 °C.
