Universal battery change with LC display for charging and maintaining 12 V car and motorcycle batteries – incl. a supply mode for battery changes without data loss

An all-rounder for maintaining 12 V batteries

The battery chargers from Trotec’s PBCS series offer you the right charger for every vehicle type. The portable battery charger PBCS 4A with a charging current of 4 amperes and a backlit LC display is a microprocessor-controlled all-round charger with a 10-stage charging cycle. Whether you use it for quick charging, reconditioning after deep discharging or to ensure that all settings remain the same when the battery is changed – thanks to its excellent full equipment, the PBCS 4A is ideal for maintaining 12 V batteries between 4 Ah and 120 Ah, for example of small cars, saloon cars and motorcycles. Both non-maintenance-free and maintenance-free 12 V batteries are supported, including wet batteries like lead acid, Ca/Ca and EFB batteries as well as gel and AGM batteries. Adapted to technically advanced and powerful batteries of modern vehicles, the charger offers you a comprehensive range of technical protective and maintenance mechanisms and ensures quick, gentle charging, thus attaining a long battery lifetime at full performance.

Protection against deep discharge, battery damage and battery-related breakdowns

If you drive a convertible with a seasonal license plate, a classic or vintage car or a motorised two-wheeler, you’ll be familiar with this problem: Low temperatures in the winter, rare use, short distance rides and age affect the battery and impair its performance. A lack of maintenance and care considerably decreases the battery’s service life. And this may well be the reason why your car refuses to start from one day to the next.

A problem that is not only time-consuming but also cost-intensive. Especially if a battery replacement is the only way to get your vehicle going again. Although battery technology is already very advanced nowadays, deeply discharged car batteries remain the most common cause of breakdowns – and there’s not always a neighbour with a jumper cable on the spot. With the trickle charging mode, the PBCS 4A protects the battery from deep discharge and maintains it at a constantly ideal charging level.

To ensure that your vehicle starts reliably

With the universally applicable battery charger PBCS 4A you ensure the reliability of your fleet and extend the service life of 12 V batteries. Problems with the battery pack are prevented, annoying starting issues are a thing of the past, important vehicle settings are maintained when the battery is changed.

The scope of equipment features and functions of the PBCS 4A comprises: 

  • Six adjustable programs (standard charging mode, AGM mode, winter charging mode, trickle charging mode, reconditioning mode, supply mode)
  • Five-stage charging progress indication (20 %, 40 %, 60 %, 80 %, 100 %)
  • Optical warning function in the case of incorrect polarity of the battery terminals (incl. reverse polarity protection functionality)
  • Practical suspension eye for wall mounting
  • Fully insulated battery terminals

The intelligent microprocessor control of the PBCS 4A monitors the multi-stage charging cycle constantly and adapts it fully automatically if required.

Operational safety is a top priority of the PBCS 4A

The charger is protected against dust and splash water by IP65 degree of protection. The PBCS 4A reliably protects the battery against excessive charge and overheating. Inadvertently reversing the battery poles during the connecting procedure is no problem either: The integrated reverse polarity protection functionality prevents short circuits, sparking as well as damage to the battery or the charger. A warning message in the LC display indicates that the battery voltage is too low or too high.

For reliable charging, care and change of 12 V batteries

The easy-to-handle PBCS 4A features the following charging programs:

Standard charging mode

The standard charging mode is suitable for charging partially discharged lead acid and gel type 12 V batteries. The cyclically optimised charging process increases the battery’s service life.

AGM charging mode

The AGM charging mode is specifically suited for charging 12 V batteries of the AGM type. The cyclically optimised charging process increases the battery’s service life.

Winter charging mode

Modern batteries (lead acid, AGM and gel) are extremely temperature-sensitive. When the ambient temperature drops below 5 °C, the chemical processes in a lead acid battery slow down. Then the winter charging mode is perfect for quickly charging 12 V batteries in cold environments (-20 °C to +5 °C) with an increased charging end voltage.

Trickle charging mode

Trickle charging mode serves to permanently and reliably compensate for the battery’s self-discharge (lead acid, AGM and gel). The maximum charging capacity is maintained constantly without damaging the battery by excessive charging. Ideally suited to prevent deep discharge of the batteries of rarely used vehicles like vintage cars or convertibles with seasonal licence plates.

Reconditioning mode for dismounted and freestanding batteries

Reconditioning mode serves to repair deeply discharged lead acid batteries to ensure that they can resume their nominal capacity. The battery’s lifetime is extended, in many cases reconditioning can prevent the necessity of purchasing a new battery. For batteries with a closed design (e.g. AGM or gel), the reconditioning mode is not suitable.

Supply mode

When a battery has to be disconnected or changed, the PBCS 4A in supply mode serves as a power source. All electronic settings of the vehicle remain unchanged.

Notes regarding the charging time of batteries with the PBCS 4A

The duration of the charging process depends on the respective charging status and the charging capacity of the battery. A five-stage charging indicator provides information on the charging progress.

Approximate charging time (up to 80 %):

  •   8 Ah: approx. 2 hours
  • 20 Ah: approx. 5 hours
  • 40 Ah: approx. 10 hours
  • 70 Ah: approx. 18 hours
  • 80 Ah: approx. 20 hours

The convenient and compact battery charger PBCS 4A extends the service life of 12 V vehicle and motorcycle batteries as well as batteries for mobile lawn mowers and ensures the reliability of vehicles that are rarely used.

The right charger makes all the difference

The choice of the right charger should be carefully considered, depending on the amount of charging energy you require for your vehicle. Trotec offers you a total of 4 battery chargers, PBCS 2A, PBCS 4A,  PBCS 6A and PBCS 10A, with a charging current of up to 10 A and a capacity of up to 200 Ah in the comprehensive car technology product rangeHere you can find an overview of the different battery chargers and their fields of application.  To make sure that you have the right charger for every application purpose at hand!
