What to check before ordering

Verify that your UPS accepts a 6 V 4.5 Ah battery with T1/F1 terminals and that the physical cartridge matches the PS-640 form factor. Confirm the terminal polarity and wiring layout against the unit you are servicing before installation.

Questions about this item

Does the PS-640 kit come with cables or mounting brackets, or do I need to buy them separately?

The kit contains one 6 V 4.5 Ah SLA battery with T1/F1 terminals and installation instructions; no cables or brackets are included.

Is the PS-640 the only capacity option in this series, or are there higher amp-hour versions I should consider?

This listing is for the 4.5 Ah model only; other capacities are not offered under the PS-640 part number.

What runtime can I expect from the 4.5 Ah battery once it is installed in my UPS?

Runtime depends on the UPS load and efficiency; the 4.5 Ah rating indicates the charge the battery can deliver, not a fixed run time.
