Note on Ordering Batteries

All the smaller SLA Panasonic batteries use spade type terminals.

There are two sizes of spade terminals (small and large).

Small size is 4.75 mm : Faston tab type 187 (4.75mm=0.187 inches hence the name) – F1

Large size is 6.35 mm : Faston tab type 250 (6.35mm=0.250 inches hence the name)- F2

UPSs – Alpha, Power Bank, PowerVAR, Soltec, TrippLite and JST Power Kinetics etc all use the 6.35mm connectors to create the lowest current density at the terminals.

To get the correct terminal size, please measure if in doubt.

MasTec will not restock batteries once sold.

Discharge Recovery:-

These SLA batteries are renowned for their ability to recover from complete discharge to still take a full charge.

After years of using SLA, MasTec has found Panasonic is unique in this ability.

Most other brands of SLAs if discharged to 0 VDC, will not recover and the battery must be removed and replaced.
