1. General Safety information
Before using the charger, read all instructions and cautionary markings on the charger, the
batteries, and all appropriate sections of this manual.
Use BS battery charger only for its use as intended purpose.
Use BS battery charger only in well ventilated rooms. Do not expose the charger to rain, snow,
spray, or bilge water. To reduce risk of fire hazard, do not cover or obstruct the ventilation
openings. Do not install the charger in a zero- clearance compartment.
Always interrupt the power supply when doing repair work on the unit.
Recommend that all wiring is done by a certified technician or electrician to ensure adherence
to the local and national electrical codes applicable in your application.
Always check that existing wiring is in good condition and that wire is not undersized. Do not
operate the charger with damaged or substandard wiring.
Always use socket which are earthed and secured by earth leakage circuit breaker.
Batteries contain aggressive acids. Avoid the contact with the battery fluid agent. If a contact
with battery fluid agent should occur, then rinse the affected parts of the body or clothing etc.
with plenty cold water. It is imperative to seek medical treatment from a doctor with injuries
caused by acid.
DO NOT disassemble the charger by yourself, which may result in a risk of electrical shock or
fire. Always refer to professional electrician or our local distributor for support.
ALWAYS interrupt both theAC and DC connect when doing repair work.
DO NOT expose lead acid batteries to a lit cigarette, sparks or flames because they produce
flammable gasses and could explode.
 NEVER charge NON-rechargeable battery.
Never try to charge a frozen battery. There is danger of explosion. In this case, place the
battery at a frost resistant location and wait until the battery has adapted to the ambient
temperature. Only by then, start the charging process.
This appliance can be used by children aged from 8 years and above and persons with reduced
physical, sensory or mental capabilities, or lack of experience and knowledge if they have been
given supervision or instruction concerning use of the appliance in a safe way and understand
the hazards involved. Children shall not play with the appliance. Cleaning and user
maintenance shall not be made by children without supervision.
Children should be supervised to ensure that they do not play with the appliance.
If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or
similarly qualified persons in order to avoid a hazard.

2. Introduction
Batteries will be permanently damaged if they are overcharged or left discharged for a period of
time. The Trident range of smart battery chargers will continuously monitor and deliver the correct
charging profile for all battery types and conditions.The built in battery management software
ensures the batteries life expectancy is maximized.
Using the latest technology and our knowledge of batteries, the Trident range of smart battery
chaRgers are specifically designed for mobile and marine applications where on-board charging
is required.
2.1 Features
Active PFC featuring smaller and higher efficiency, max 88%
Multiple isolated outputs, including slave charger for starter battery
Automatically work as power supply or charger
Sophisticated TBB premium II multiple stages charging algorithm for lead acid battery
Suitable for lithium batteries.
Automatic temperature compensation charging.
Automatic voltage compensation charging
Programmable with software
Special silent design
TBB premium II multistage adaptive charging algorithm for lead acid battery
Fitted with multistage charging algorithm (bulk-absorption-float-recycle), BS battery charger is
designed to charge battery quickly and fully. Microprocessor controlled charging algorithm with
variable absorption charging timer guarantee the optional charging for batteries of different
discharged state.

Float charging and Recycle charging program guarantees your battery will be properly maintained
in the event of long-time fixed installation.
Battery temperature compensation
Battery temperature is a key factor in correct charging, the charging formula must be adjusted
(automatically and in real time) according to the actual battery temperature to ensure that
battery are fully charged but not overcharged or undercharged.
All charging voltages recommended by battery manufacture are in fact only applied at 20℃-
25℃.
The battery temperature and voltage sensor supplied with BS charger measures the
temperature of battery and automatically adjusts in real time to properly charge your batteries at
compensation rate of –4mv / ℃/ cell.
In case the battery temperature sensor is not present, BS charger will use 25℃as default
setting.
Voltage compensated charging
Through the battery temperature and voltage sensor, BS charger will automatically adjust its
output, compensating the voltage drop on the cable ensuring the correct charging current and
voltage is delivered the battery.
Charging current adjustable
Using the multifunctional smart button, user can choose the different charging current
according the battery capacity. We recommend the charging current set as 10%-20% of battery
capacity (I=0.1C/0.2C) for lead acid battery and 30% of battery capacity for lithium battery.
Slave battery charger for starter battery（In addition to 12V10A model）
Along with a powerful charger for stationery/service battery, BS battery charger also offers a
slave charger of max 3A to keep starter battery charged.
Special silent design
User-friendly special silent design. The fan of charger will stop working after the charging
current drop to a predetermined level for a period of them. And it will then automatically resume
working if internal temperature increases.
Using the Silent button on the remote control (optional accessory), the BS battery charger will
automatically to reduce the output of the charger and stop the fan.
