Power-Sonic PS-1270 F2 — 12 V 7 Ah valve-regulated sealed lead acid battery on F2 quick-disconnect tabs, from the PS general purpose float series.
A standby battery sits on constant float charge for years and then has to deliver alarm current without warning, which is what a float cell is built for rather than a cycling cell. Power-Sonic names fire and security systems, emergency lighting and UPS among the applications for this series.
- 12.0 V nominal, six cells; 7.0 Ah at the 20-hour rate (0.35 A to 10.5 V)
- 6.53 Ah at 10 hours, 6.05 Ah at 5 hours and 4.27 Ah at 1 hour
- 5.94 × 2.56 × 3.70 in. (151 × 65 × 94 mm), 3.94 in. over the terminals; 4.34 lb
- Internal resistance approximately 33 mΩ; maximum short circuit current 196 A
- F2 is a 0.250 × 0.032 in. faston quick-disconnect tab
- Float 13.5 to 13.8 V and cyclic 14.1 to 14.7 V at 20 °C; discharge 5 to 140 °F
- ABS case to UL94 HB; UL 1989 and IEC 60896
The 9 Ah PS-1290 F2 shares this case exactly and drops into the same space, but it is not the same cell: 17 mΩ against 33, 252 A short circuit against 196, 5.56 lb against 4.34. The PSL-SC-1270 F2 is lithium at 12.8 V nominal and is not a drop-in.

FAQ
What is the PS-1270 F2 rated at?
12 V nominal and 7.0 Ah at the 20-hour rate.
What does F2 mean?
F2 is the terminal type: a 0.250 x 0.032 in. faston quick-disconnect tab.
How should it be charged?
For cyclic use Power-Sonic specifies a constant voltage charge of 14.1 to 14.7 V at 20 °C; for standby, float at 13.5 to 13.8 V.
Is there an F1 version?
Yes. The PS-1270 is also available with F1 terminals.
