Two-pack replacement batteries

This set contains two 12 V 35 Ah sealed lead-acid batteries built to U1 form factor with FP terminals. Each unit weighs 23 lbs and measures 7.72 in long, 5.16 in wide and 6.1 in high. They are supplied as direct replacements for electric wheelchair and scooter applications.

Suitability check

The pack suits owners who need a matched pair of 12 V 35 Ah SLA units with FP terminals and the exact U1 dimensions listed. Buyers whose equipment requires a different voltage, capacity, terminal style or case size should look elsewhere. The batteries ship without cables or connectors, so existing hardware must be reused.

Critical specification

Terminal type FP is the single detail that decides fit; the battery will not connect if the device uses a different terminal layout. Verify the FP terminal against the unit being replaced before ordering. All other dimensions and the 35 Ah rating follow the standard U1 envelope.

Questions about this item

Does the 12 V 35 Ah sealed lead-acid battery generate noticeable heat or noise during all-day use?

Sealed lead-acid chemistry runs silently and produces minimal heat under normal discharge; no fan or active cooling is involved.

What existing hardware must I reuse for the FP-type terminals to connect properly?

You need to reuse your current cables, connectors and mounting hardware that match the FP terminal layout on your wheelchair or scooter.

Will the 7.72 × 5.16 × 6.1 in dimensions fit the same U1 battery tray I already have?

The pack matches standard U1 footprint; verify your tray measures at least 7.72 in long, 5.16 in wide and 6.1 in high before ordering.
