Reserve Deep Cycle Battery LFP1255D,capacity :12V55Ah batteries is Sealed Lead Acid Battery.The discharging capacity of battery depends on the discharge rate being used and ambient temperature.
Figure 1,2 and 3 show the different discharging current corresponding to discharging capacity at 20 OC(68OF) to 25OC(77OF) for FP, LFP and CFP types batteries.
They show that the rated capacity of a battery is reduced when it is discharged at a value of
current that exceeds its 10-hours or 20-hoursrate.
can be used for just about every application, including: UPS Backup Systems, Alarm Systems, Fire Alarm Systems, Medical Equipment, Test Equipment, and much more.
