Replacement batteries for the Symphony EBM3618RT2U

The Uniti Power URBK1 is a replacement battery kit for the Symphony EBM3618RT2U 36V external battery module, used with the Symphony SPY1500RMi2U 1.5kVA UPS. Each EBM3618RT2U takes two URBK1 kits, so a full battery replacement for one module needs two kits. URBK1 uses maintenance-free VRLA batteries and carries a 2-year repair-or-replace warranty.

UPS batteries are consumable components. Their available capacity gradually reduces with age, temperature and usage, even while the UPS electronics remain fully serviceable. Replacing ageing batteries with the specified Uniti Power kit restores the battery performance the module was designed for and keeps the electrical, physical and runtime characteristics of the original system, without changing the UPS electronics.

Compatibility

This is the only URBK1 application confirmed in Uniti Power's published data. For the internal batteries of a SPY1500RMi2U, or for any other Uniti Power unit, confirm the correct kit with Uniti Power technical support before ordering.

Fitting the kit

Battery replacement should be completed by competent personnel, following the EBM3618RT2U and UPS user manuals. To get the best life from the new batteries, keep the module within its optimal 20-25°C operating temperature: the battery module datasheet notes that operation outside this range may reduce battery life and performance.

Warranty and support

URBK1 is covered by a 2-year repair-or-replace warranty. See warranty information for full terms.
