    Current that exceeds this value will be interrupted by the battery’s protection circuitry. Although high ripple current at low frequencies (60Hz/120Hz) is not recommended, the ALM 12V7 s-Series battery will support average ripple current with peaks up to 53 amps without any adverse effects. As a comparative example, the maximum ripple current for a typical AGM (absorbent glass mat) 12 volt 7 Ah VRLA battery (@ 20hr rate) would be 7 Ah/20 hr or 0.35 amps.

  • Page 29: Over Discharge Protection Under Voltage Protection (Uvp)

    The ALM 12V7 s-Series is designed to enter an Under Voltage Protection (UVP) state if any cell drops below 2 volts. In the UVP state, the ALM 12V7 s-Series battery will disconnect its terminals causing the output voltage to drop to 0 volts. Slight differences in the cells’ state of charges lead to differences between the cell voltages, especially at low states of charge.

  • Page 30: Smart Charger Support

    ALM12V7 s-Series batteries are designed to enter an Over Voltage Protection (OVP) state if any cell rises above 4.1 volts. In the OVP state, the ALM 12V7 s-Series will disconnect its terminals and not accept further charge current. To exit the OVP state, apply a load to discharge to the battery.

  • Page 35: Charge Rate By Temperature

    For charge acceptance, do not exceed the limits specified. For the higher temperatures (and charging rates), exceeding these rates may result in engaging the ALM 12V7 s-Series protection circuitry. For lower temperatures, exceeding these rates will result in a shorter battery life.

  • Page 40: Alm 12V7 S-Series Typical 50W Constant Power Discharge Behavior

    12V7 s-Series User’s Guide Chapter 5: Operation and System Design Considerations Voltage drop in the ALM 12V7 s-Series is an inverse function of the ALM 12V7 s-Series battery’s internal temperature. As the internal temperature of the ALM 12V7 s-Series drops, the impedance rises leading to an increased voltage drop.

  • Page 41: Balancing

    Balancing Over time, the ALM 12V7 s-Series cells diverge in both capacity and SOC. All ALM 12V7  s-Series batteries perform cell voltage balancing at high SOC values based on cell voltage to maximize the available capacity of the battery. The balancing circuit’s purpose is to drive all cells to the same voltage.

  • Page 42: Shelf Life

    Storage temperatures above 25 °C accelerate the rate of self-discharge and reduce the shelf life. At 10% SOC, the ALM 12V7 s-Series battery has about 5% of usable energy, on average, before entering into an Under Voltage Protection (UVP) state as described in Over Discharge 406014-02EN, Rev.
  • Page 43 Under Voltage Protection UVP state there is a limited time that the battery can remain without being charged. If the ALM 12V7 s-Series battery is discharged to the UVP 5% SOC level, it has approximately 30 days in this state, at 25 °C, before reaching its lowest power mode called the Under Voltage Lock-Out (UVLO) state.
