SmartCharge 4A Portable Battery Charger
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.
Product warnings
- This product is not intended for use by children or people with reduced physical, sensory or mental capabilities, unless under the supervision of a person responsible for their safety.
- Children shall not play with the appliance.
- Children shall not clean or maintenance the appliance without adult supervision, the appliance shall be repaired by the professionals.
- The mains’ power supply cord cannot be replaced. If the cord is damaged, discontinue usage.
- This charger is designed for use only with LEAD/ACID type (both open and closed) batteries including AGM, GEL and Calcuim types; and for battery sizes 12V/8–225Ah. The charger should not be used for other battery types. Recharging the non-rechargable batteries is forbidden!
- Batteries can emit explosive gases during normal charging. Avoid sparks in the immediate area and always provide proper ventilation during charging.
- Connect the chargers plus clamp to the plus terminal on the battery. Connect the minus clamp to the chassis of the vehicle away from petrol pipes. Connect then to the wall socket.
- After charging, power-off the charger and disconnect from the mains’ power supply. The minus and plus terminals can then be disconnected.
- This charger includes high-strength magnets and should not be placed in close proximity to magnetic storage devices such as computer hard drives and tape media.
Charging phase details
Provide chargers for a variance of vehicles and equipment such as motorbikes, snowmobiles, lawnmowers and boats etc.
Battery Type
Lead acid battery (open and closed types), AGM and Gel batteries included.
Pre Analysis
The charger checks if the battery is correctly connected. The battery’s charge
level (V) and total capacity (Ah) is measured to determine the correct
settings for charging.
| Battery voltage | Battery status | LED indication |
|---|---|---|
| >12.65V | 95–100% | All segments on |
| 12.55V–12.65V | 80% | 4 segments on |
| 12.45V–12.55V | 60% | 3 segments on |
| 12.35V–12.45V | 40% | 2 segments on |
| 2.0V–12.35V | 0-20% | 1 segment on |
Charging
The charger starts charging the battery with constant current up to 14.4V (at
25°C). The charge voltage is then held constant at 14.4V and the charging
current is reduced until it is below a defined level. The charge voltage then
drops to 13.8V, before the long-term charging phase starts. During charging,
battery charge is shown by the number of LEDs illuminated. The blinking
segment above these LEDs indicates active charging. Once full battery charge
is reached, all 5 LED segments remain illuminated.
If the measured battery voltage is below 2.0V, the charger will enter Error
Mode.
Post Analysis
The charger analyses the battery again after the charging phase. If the
charger detects an error in the battery, the warning triangle will flash. Post
analysis can detect batteries with a short circuit in individual cells. This
cannot be detected in the pre analysis. If the battery voltage drops below
12.5V within 2min, the charger will go into error mode.
The charging sequence will be stopped.
Long-term charging
240 hours after the battery is fully charged, the charger will go in to Sleep
Mode. This is indicated by all battery LEDs slowly pulsating. This mode has a
very low power consumption. After a week in Sleep Mode, the charger will wake
up and begin a new charging cycle. The charger will also wake up and start a
charging cycle if battery voltage drops below 12.6V.
Additional charger functionality
Temperature based voltage compensation
The charger automatically adjusts the charging voltage to the correct level
according to the ambient temperature. The default ambient temperature is 25°C.
Voltage is reduced for higher ambient temperatures and increased for lower
ambient temperatures. The correct amount is ±0.03V/°C. Max temperature
compensate charging voltage is 15.3 V.
14.7V button
Some batteries require a higher charging voltage than other batteries. If the
14.7V button is activated the initial charging voltage will be 0.3V higher
than the standard level.
Before activating this button, the 14.7V charge voltage requirement should be
confirmed. If a battery requires this higher charge voltage, it will be
described on the battery.
Power Supply mode
Keep pressing the button until the LED shines one by one in a regular buttom
to the top cycle, the charger will start power supply mode. In this mode, the
charger supply 13.6V.
If the output short circuit or connect with incorrect polarity in this mode,
the charger will go into error mode. You should press the power button to turn
off the charger, then restart the charger (go to charger or power supply
mode).
Automatic restart after power interruption
If the mains’ power supply is temporarily interrupted, the charger will
continue charging when the power supply returns.
