GOOWEI ENERGY Pb backup battery VRLA GEL 12V 250Ah (OTL250-12)

GOOWEI ENERGY OTL250-12

Lead 12 V (250 Ah) battery in VRLA GEL design designed for deep discharge and cyclic stress. It is thus suitable for backup systems.

Traction gel accumulators of the OTL series. These are sealed lead accumulators in the VRLA design. It is a construction in which internal pressure is regulated using valves (VRLA - Valve Regulated Lead Acid = valve-controlled lead-acid accumulators). GEL technology means that the battery does not contain an electrolyte in a liquid state. The electrolyte is solidified in a hybrid gel (combination with AGM) and is thus firmly bound in the bowels of the battery cells, thereby preventing its leakage. The extra strong grid of cells ensures high cyclic endurance of the battery.

The battery can also be used for applications in "standby" mode, when the batteries are permanently powered and serve as a backup source in the event of a power failure. They are especially suitable where there are frequent outages or where the batteries are deeply discharged.

Properties

• Hybrid GEL = the electrolyte is bound in a hybrid gel (combination with AGM)
• Higher maximum discharge currents
• Absolutely maintenance-free (in terms of water refilling)
• Much longer cycle life than a conventional flooded battery
• During cyclic operation, charging voltage 14.5 - 14.9 V at a temperature of 25 °C (cyclic application)
• When operating the backup source, charging voltage 13.6 - 13.8 V at a temperature of 25 °C (station application)
• Deep Discharge Resistance (Resists deep discharge better)
• Vibration-proof
• Indestructible block (Leak-Proof) - the battery can work permanently at an angle of inclination of up to 90°
• It is not a dangerous product of the FAA and IATA category (batteries can therefore normally be transported by air and by sea)
• Lifetime: 800 cycles (at 50% discharge depth)
• Connector type: M8 internal thread

Batteries are intended primarily for the following applications

• Uninterruptible Power Supplies (UPS)
• Electronic fire protection systems (EPS)
• Electronic security systems (EZS)
• Telecommunication equipment
• Emergency lighting
• Powering electric motors and other traction EV applications
• Backup of circulation pumps and boilers

Maintenance of batteries

In order to achieve optimal battery life with frequent cyclic operation, it is necessary to respect the maximum permitted discharge depth of 80% D.o.D. (Depth of Discharge) specified by the ČSN EN 61044 standard. When storing batteries for a longer period, it is necessary to ensure their continuous charging. At a storage temperature of 25 °C, charge every 6 months, if the temperature is higher, charge more often. Operating temperature range: charging -20 to +50 °C, discharging -20 to +50 °C, storage -10 to +40 °C. Long-term exposure of batteries to temperature extremes shortens their lifespan.
