Battery AVACOM DeepCycle 12V 20Ah PBAV-12V020-M5AD - sealed lead-acid rechargeable

The AVACOM DeepCycle 12V 20Ah sealed lead-acid rechargeable battery (model PBAV-12V020-M5AD) provides a nominal voltage of 12 V and a capacity of 20 Ah. Designed for both cyclic and standby applications, this VRLA (valve-regulated lead-acid) battery features a maintenance-free construction that allows indoor installation under moderate ambient temperatures. The battery is intended to deliver reliable power for medium-load systems where a sealed, spill-proof solution is required.

Advantages

The sealed VRLA design eliminates the need for regular electrolyte maintenance and reduces the risk of leaks, while the deep-cycle construction supports repeated charge and discharge cycles with improved cycle life compared with standard starter batteries. Its compact form factor and standardized terminal arrangement simplify installation in cabinets and portable enclosures. The battery is compatible with common charging algorithms for lead-acid chemistries and offers stable voltage delivery for backup and off-grid equipment.

Suitable for

• Uninterruptible Power Supplies (UPS) for small to medium systems
• Standalone and hybrid solar energy systems
• Electric scooters and mobility devices
• Emergency lighting and alarm systems
• Portable equipment and field instruments requiring rechargeable backup

How to use

Before installation, verify that the battery dimensions and terminal polarity match the equipment requirements. Use a compatible charger or charging system configured for sealed lead-acid deep-cycle batteries and follow the manufacturer's recommended charging voltages and current limits. For standby applications, keep the battery connected to a float or standby charger to maintain charge. For cyclic use, follow a charge/discharge regimen appropriate to the depth of discharge to extend service life. Ensure proper ventilation, avoid exposing the battery to temperatures outside the recommended range, and secure the battery to prevent movement during operation.

Usage recommendations

To maximize service life, avoid deep discharges below recommended depth-of-discharge limits and store the battery in a partially charged state if it will be idle for extended periods. Periodically check terminal connections for corrosion and ensure charging equipment is set for sealed lead-acid chemistry to prevent overcharging.
