Gel battery CARSPA GE40-12 12V 40Ah for UPS and backup power

Sealed gel battery CARSPA GE40-12 is a 12V 40Ah energy storage unit designed for stationary backup and uninterruptible power supply (UPS) applications. The maintenance-free, spill-proof gel electrolyte and robust housing provide long standby performance and safe operation in upright or horizontal installations. With deep-cycle capability, this battery is intended to deliver stable voltage for UPS systems, alarm systems, emergency lighting and similar backup power uses.

Advantages

The gel construction ensures low self-discharge and high resistance to vibration and leakage, enabling reliable long-term storage and repeated discharge/recharge cycles. Maintenance-free design eliminates the need for electrolyte refills and reduces service interventions. Compact dimensions and multiple mounting options make it suitable for confined equipment racks and cabinets. The battery provides consistent output voltage under typical load conditions and supports long standby times when used in UPS and emergency power systems.

Suitable for

• Home and office UPS units for computers and network equipment
• Emergency lighting and exit sign backup
• Alarm and security systems
• Small-scale renewable energy storage and standby power for telecom devices
• Laboratory and test equipment requiring reliable DC backup

How to use

Install the gel battery in a dry, well-ventilated area within the equipment cabinet or rack, observing the manufacturer’s recommended polarity and terminal connections. Ensure the charger or UPS is configured to the correct nominal voltage and charge profile for gel-type lead-acid batteries to maximize service life. Avoid short-circuiting the terminals and protect against incorrect polarity when connecting to systems. For storage, keep the battery at moderate temperature and recharge periodically to compensate for self-discharge.

Usage recommendations

Use a charger or UPS with a charge algorithm suitable for gel batteries and include regular checks of terminal connections and voltage. Store the battery charged and perform periodic recharge during long storage intervals. Replace the battery when capacity falls below the required runtime for your application.
