Designed for standby use in uninterruptible power supplies (UPS).
The internal resistance of this battery is lower than for EP 7 — 12 but container dimensions are the same.
That is why EV 9 — 12 has higher capacity and much better constant power and constant current discharge characteristics, especially for short discharge times (5-20 min.)
