  • Product typeKit/Package
  • Product weight15
  • 12V 18Ah SLA chemistry delivers reliable backup power

Purpose & fit

This is a 12 V 18 Ah sealed lead-acid replacement battery kit for uninterruptible power supplies. It suits IT managers and home-office users who need a single drop-in cartridge to restore backup runtime. The pack is not intended for applications that require multiple battery strings or higher-capacity modules beyond 18 Ah.

Sustained-load behaviour

The high-rate discharge chemistry is designed to deliver steady current during extended mains outages rather than only short bursts. Factory-fresh cells help maintain consistent voltage across the discharge curve so connected servers or networking gear stay powered until utility supply returns or a graceful shutdown completes.

Compatibility check

Verify that your UPS specifies a 12 V 18 Ah SLA cartridge with the same physical footprint and terminal layout before ordering. The kit includes installation instructions, but it does not contain mounting hardware or cables, so confirm whether your chassis reuses existing connectors or requires additional parts.

Questions about this item

How much heat does the 12V 18Ah SLA battery generate during continuous float charging?

The sealed lead-acid chemistry produces minimal heat while on float charge; normal ventilation inside the UPS cabinet is sufficient.

What existing UPS hardware is required to install this replacement cartridge?

You need a compatible UPS unit that accepts a single 12V 18Ah brick and the original cable harness or Anderson-style connectors.

Will this 15 kg battery fit the same tray and connect to the original terminals in my older UPS?

Yes, the Wong Long WP18-12 matches standard 12V 18Ah dimensions and terminal layout for direct drop-in replacement.
