SKU CH-XPC8-W3KRG

Kit of two 6 V 9 Ah sealed lead-acid batteries for MGE Pulsar ESV5 UPS units

  • TypeKit/Package
  • Weight8
  • Two high-rate 6 V 9 Ah SLA cells power the ESV5 UPS
  • Factory-fresh batteries deliver reliable backup when mains fail
  • Kit includes both cells for a complete single-install swap
  • Comprehensive fitting instructions enable straightforward self-installation
  • Built for dependable performance in critical power-protection roles

Ready for Eaton-MGE Pulsar ESV5

This kit supplies two factory-fresh 6V9A sealed lead-acid batteries built as direct replacements for the Eaton-MGE Pulsar ESV5 uninterruptible power supply. It restores backup runtime without requiring modifications to the existing UPS chassis. The pack is intended for IT staff or facility managers who maintain this specific UPS model and need a drop-in refresh.

High-rate discharge under load

Each 6V9A cell is rated for high-rate discharge, meaning it delivers the current spikes demanded during a mains failure or self-test without excessive voltage sag. The chemistry is optimised for standby service rather than deep cycling, so capacity remains stable across repeated brief outages. Runtime scales with the connected load; the kit does not alter the UPS firmware or charging profile.

Simple cartridge swap

The two batteries arrive pre-wired as a matched pair with installation instructions included. Typical replacement involves powering down the UPS, opening the battery compartment, disconnecting the old pack and connecting the new one using the existing terminals. Polarity is keyed, but reversing the leads will prevent start-up. No soldering or firmware update is required.

Questions about this item

How much heat or noise should I expect from the two 6 V 9 Ah batteries during continuous UPS operation?

The sealed lead-acid cells produce no fan noise and only minimal warmth under normal float charge; measurable heat appears only during extended discharge or recharge cycles.

What existing hardware must I already have to install this kit in my UPS?

You need an MGE Pulsar ESV5 UPS with its battery compartment accessible and the original wiring harness in place; the kit includes two 6 V 9 Ah cartridges and printed replacement instructions.

Will the 6 V 9 Ah cells work correctly if my Pulsar ESV5 still uses the original charger firmware from several years ago?

Yes — the batteries match the original voltage, capacity and high-rate discharge profile, so the UPS charger firmware requires no update to recognise and charge them properly.
