Combining fully automatic operation, the ability to properly charge multiple battery types and engine starting assistance capabilities, the PRO-LOGIX PL2545 is an ideal all-purpose charger to meet the needs of technicians and home enthusiasts. Intelligent, beneficial, safe and versatile – one charger does it all, from fast charging and battery repair to engine starting assistance and long term storage charging. Plus, with the ability to properly charge virtually any lead acid battery type, it is the only charger you will need. Flooded, AGM, Gel Cell, Spiral Wound, Marine and Deep Cycle batteries all can be charged right with the PL2545.
The charger uses a proprietary Multi-Stage charging process designed to optimally charge and maintain batteries. An example is shown above. The representation above shows the charging routine when charging a deeply discharged AGM battery in the 20A setting.

ENERGIZING PHASE
The charging process includes an initial energizing mode in which the charger determines the best charging path for the connected battery. From there, the charger can enter the Fast Charge stage (most cases), Soft Start Mode, Battery Repair Mode or stop the charging routine because unsafe battery conditions (short, etc.) are detected.
SOFT START MODE
Soft Start Mode is activated when the charger is connected to a deeply discharged battery. This mode protects the battery during the initial charge period, as the battery’s voltage rises to a more normal level, and is beneficial for the long-term health of the battery. If this mode is activated, the display will read Soft Start Mode Engaged.
BATTERY REPAIR MODE
During the Energizing Phase, if the charger detects the presence of battery sulfation, it will activate If this mode is engaged, the display will read Battery Repair Mode Engaged. This indicates the charge time will be extended while the charger attempts to recondition the battery.
PRO-LOGIX PHASES 5-7: IDEAL BATTERY MAINTENANCE
A key feature of this charger is how it manages a battery that remains on the charger after a complete charge has been achieved, such as during the storage of a seasonal use vehicle. Once the charger reaches the Resting Phase, its output is virtually turned off, except to occasionally monitor battery condition. This is beneficial for the connected battery, as it reduces chemical reaction within the battery compared to traditional charger maintenance modes. This greatly reduces the chance of damaging a battery in long-term storage.
In addition, in Phase 6 Exercising, we introduce a load on the battery, simulating active use, and then recharge the battery to full charge. This Exercising feature keeps the battery in optimal condition during periods of storage and non-use.

ADDITIONAL FEATURES
MULTIPLE BATTERY COMPATIBILITY
The charger will properly charge a wide variety of battery types, including Conventional, Maintenance Free, AGM, Spiral Wound, Gel Cell, Marine and Deep Cycle batteries.
SMART CLAMP TECHNOLOGY
The charger will send power to the output leads only when a proper battery connection is made.
REVERSE POLARITY PROTECTION
Guards against reverse connections. When this protection mode is engage, the display will read Reverse Polarity Detected and power will not be sent to the output cables/clamps until the reverse condition is corrected.
BATTERY FAULT PROTECTION
Guards against excessively charging compromised batteries. When this protection mode is engaged, the display will read Battery Error – Suspect Bad Battery and power will not be sent to the output cables/clamps. Conditions that cause this error include: if the battery voltage does not rise appropriately during the charging process (indicating a shorted cell) or if the maximum charge time has been exceeded.
SHORT CIRCUIT PROTECTION
Guards against shorted connections. When this protection mode is engage, the display will read Battery Error – Suspect Bad Battery and power will not be sent to the output cables/clamps.
OVER-VOLTAGE PROTECTION
Guards against charging errors where the charger is programmed to charge in a different voltage than the detected voltage of the battery. When this protection mode is engage, the display will read Charging Stopped – Voltage Error and power will not be sent to the output cables/clamps.
OVERHEAT PROTECTION
Guards against overheat conditions within the charger. When this protection mode is engaged, the display will read Overheat Condition Detected and power will not be sent to the output cables/clamps. Once the charger cools down, it will resume charging.
