The Automatic Charger Pb 2425 SMT 3B from Votronic (MPN 6239) is a modern battery charger for mobile use. It has charging programs for GEL, AGM, acid and modern lithium batteries and is designed for 24 V battery voltage. The charging current at the main output is 25 A. Additionally, there is an auxiliary charging output for the starter battery, which can supply an additional 4 A charging current. The device is suitable for batteries with a capacity of 46 Ah - 290 Ah.

• Important features of the Pb 2425 SMT 3B battery charger
• Reliably charges GEL, AGM, acid and LiFePO4 batteries

The charging voltage is free of peaks and regulated so that overcharging of the batteries is excluded.

• Fully automatic continuous operation: The charger can remain permanently connected to the battery and keeps it fully charged. In case of power failure, the batteries are not discharged (disconnection by safety switch).
• Lithium LiFePO4 maintenance, auto wake up

Lead battery regeneration during long standstill twice weekly against harmful acid stratification.

• Parallel and buffer operation: With simultaneous consumption, the battery continues to be charged or kept fully charged. The adaptation of charging times is calculated and monitored automatically by the charger.
• Unattended charging: Multiple protection against overload, overheating, overvoltage, short circuit, reverse polarity, malfunction and battery reverse discharge through electronic regulation up to complete disconnection of charger and battery by built-in safety switches.

Connection for battery temperature sensor (accessory temperature sensor 825): For lead batteries (acid, gel, AGM), the charging voltage is automatically adjusted to the battery temperature, resulting in better full charge of the weaker battery in cold conditions, and avoiding unnecessary battery gassing and thus battery stress in summer temperatures.

For LiFePO4 batteries, the battery temperature sensor is required for function: It serves as battery protection at high and especially at low temperatures below 0°C.

Charging aid for deeply discharged lead batteries: Gentle pre-charging of the (lead-acid, -gel, -AGM) battery up to 8 V, then powerful support of the battery with possibly still switched-on consumers.

Disconnection of batteries in case of power failure, overheating, malfunction (safety switch per charging output).

Separate auxiliary charging output "S" for support and float charging of the vehicle starter battery.

Charging current distributor optionally switchable to own charging program for starter battery.

Starter battery is charged with full charging current if required (short vehicle standstill).

• Battery capacity 4-way adjustable (total 12 charging programs).

Inputs for voltage sense lines, optionally usable for overlong charging cables and/or external lossy diode charging current distributors.

Mains/charging power reducible with weak or limited mains supply, e.g., weakly fused shore power supply, generator operation etc. (Power Limit function)

• Overview of the charging programs of the Pb 2425 SMT 3B
• "Gel": Charging program for gel batteries, characteristic IU1oU2oU3. Matched to sealed, gas-tight gel/dryfit batteries with fixed electrolyte, which generally require a higher charging voltage level and longer U1 holding times to achieve short charging times with particularly high capacity storage and to avoid long-term battery "starvation".
• "AGM": Charging program for AGM/fleece batteries, characteristic IU1oU2oU3. Intended for charging sealed, gas-tight AGM (Absorbent Glass Mat) batteries in lead-fleece technology, which require a particularly high U1 level with matched holding times for full charge and then a moderate U2 level for float charge (plate and round cell technology).
• "UNIVERSAL": Charging program for lead-acid/wet/AGM batteries, characteristic IU1oU2oU3. Universal program for charging and float charging of acid batteries in vehicles (mixed mobile/stationary). Offers with medium U1 level still short charging times, good charge factor and good acid mixing for open and closed, low-maintenance, maintenance-free standard, traction, lighting, solar and heavy duty batteries, as well as AGM batteries with normal U1 level.
• "LiFePO4": Charging program for lithium batteries, characteristic IU1oU2oU3. Charging program matched to lithium LiFePO4 batteries with own BMS and prescribed or built-in protection circuitry. A special rest maintenance automatically keeps the LiFePO4 battery at a charge level of 50-80% beneficial for lifespan when the vehicle is parked (seasonal operation) and also buffers 12 V consumers and the vehicle starter battery. In addition, a regular auto wake-up function activates the battery cell balancing.
