Power-Sonic PS-1270 F1 — 12 volt, 7.0 Ah sealed lead acid AGM battery with F1 faston terminals.
This is the standard sealed lead acid size for standby power in fire alarm and security panels, emergency lighting and small UPS equipment, where the battery floats for years and delivers its rated capacity only during a mains failure.
- 12.0 volts nominal from six cells; 7.0 Ah at the 20 hour rate, 0.35 A down to 10.5 volts
- 6.53 Ah at 10 hours, 6.05 Ah at 5 hours, 4.27 Ah at the 1 hour rate
- F1 faston quick-disconnect tabs measuring 0.187" × 0.032"
- 5.94" long × 2.56" wide × 3.70" high, 3.94" over the terminals; about 4.34 lb
- Internal resistance about 33 mΩ; maximum short circuit discharge current 196 A
- Float charge 13.5 to 13.8 volts, cyclic charge 14.1 to 14.7 volts at 20 °C
- Discharge 5 to 140 °F, charge -4 to 122 °F; UL 1989 and UN2800 non-spillable
Read the suffixes carefully. The case here is ABS; Power-Sonic supplies UL94 V-0 flame retardant material only under the FR designation, as in PS-1270 FR F1, so do not assume one here. PS-1270 F2 is the same battery with the wider 0.250" tab.

FAQ
What terminals does the PS-1270 F1 have?
F1 faston terminals. The PS-1270 F2 is the same battery with the wider F2 terminal.
What float voltage should the charger use?
For standby (float) service, 13.5 to 13.8 V for the 12 V monobloc at 20°C. For cyclic use, 14.1 to 14.7 V with initial current below C/5.
How long does it last on float?
Power-Sonic shows a float life of about 5 years at 20 to 25°C, dropping at higher temperatures (about 1.9 years at 40°C).
Is the case flame retardant?
The standard case is ABS (UL94 HB). UL94 V-0 flame retardant cases are available as the FR versions, such as PS-1270 FR F1.
