Projecta PC800
Pro-Charge Battery Charger
12V 8A 6 Stage Switchmode Battery Charger
The Projecta PC800 is a 12V 8A Pro-Charge automatic battery charger designed for charging and maintaining 12V lead acid batteries.
It uses a 6-stage automatic charging process to help charge, test and maintain the battery. Once charging is complete, the charger moves into float mode and can remain connected to maintain the battery.
The PC800 is suitable for most 12V automotive, marine and deep-cycle lead acid batteries, including GEL, AGM, WET CELL and Calcium batteries.
The PC800 includes:
6-stage automatic charging
Normal and Calcium charge modes
Manual Rejuvenation mode
Adjustable charge rate
Switchmode technology
Spark-free protection
Reverse polarity protection
Moulded battery clips
Side mounting wings
Cooling vents
Float maintenance charging
The PC800 is designed for 12V lead acid batteries only.
It is suitable for:
GEL batteries
AGM batteries
WET CELL batteries
Calcium batteries
Automotive batteries
Marine batteries
Deep-cycle batteries
No.
The uploaded manual states the PC800 is for 12V lead acid batteries only.
Do not use the PC800 to charge lithium batteries.
Recommended battery range:
Deep cycle: 14–160Ah
Automotive: 80–1000CCA
Marine: 110–1300MCA
No.
The PC800 is a 12V charger only.
The PC800 uses a 6-stage charging process:
Rejuvenation — Manually initiated 24-hour high frequency charge to help break down sulphation.
Soft Start — Gently introduces power to the battery.
Bulk — Charges at maximum current up to the set voltage.
Absorption — Charges the battery to 100% using controlled voltage.
Battery Test — Checks whether the battery has accepted charge.
Float — Maintains the battery at full charge without overcharging.
In Calcium mode, the charger also uses an Equalisation stage to support calcium batteries.
Yes.
When the battery is fully charged, the green Float / Full LED illuminates and the charger moves into float mode.
The charger can remain connected to maintain the battery.
Normal mode is used for most 12V lead acid batteries, including:
GEL
AGM
WET
Calcium mode adjusts the charge profile for calcium batteries.
It includes an Equalisation stage that can raise the battery voltage to support recovery of deeply discharged calcium batteries.
Rejuvenation mode is manually started and runs a high frequency intermittent charge for up to 24 hours.
It may help restore tired or sulphated batteries.
To start Rejuvenation mode, hold the Battery Type button for approximately 3 seconds until the Rejuvenation LED starts flashing.
To stop Rejuvenation mode manually, hold the Battery Type button again for approximately 3 seconds.
The PC800 supports:
2A
4A
8A
Select the charge rate based on the battery size.
Recommended guide:
2A: 14–40Ah deep cycle / 80–240CCA automotive / 110–330MCA marine
4A: 30–80Ah deep cycle / 180–480CCA automotive / 250–650MCA marine
8A: 60–160Ah deep cycle / 360–1000CCA automotive / 500–1300MCA marine
Before using the PC800:
Read the instruction manual.
Use indoors only.
Do not expose the charger to rain.
Charge in a well-ventilated area.
Keep flames, sparks and smoking materials away from the battery.
Do not charge a frozen battery.
Do not charge a damaged or non-rechargeable battery.
Turn off vehicle accessories before charging.
Disconnect the 240V mains supply before making or breaking battery connections.
Most vehicles are negative earth.
Yes.
The PC800 can be hard wired to the battery for permanent installations.
Required fuse rating:
PC800: 10A fuse
Connection:
Any modification to the 240V mains lead must be carried out by a qualified person.
The PC800 uses coloured LEDs to show charging stage.
Bulk blue LED — Soft Start, Bulk, Absorption and Equalisation stages
Full green LED flashing — Analysis stage
Full green LED solid — Float / fully charged
Rejuvenation amber LED flashing — Rejuvenation mode active
Fault red LED — Fault condition present
Check the following:
Battery voltage is above 3.0V.
Battery clamps are connected correctly.
Red clamp is connected to positive +.
Black clamp is connected to negative – or correct chassis earth.
The 240V mains outlet is switched ON.
The correct battery type is selected.
The battery is not frozen, damaged or faulty.
The PC800 is designed to start charging from 3.0V. If the battery voltage is lower than 3.0V, the charger may not start.
If the battery is below 3.0V, the charger may not detect it.
The manual advises that booster cables can be used between two batteries to provide more than 3.0V to the battery being charged. Once the charger starts charging, the booster cables can be removed.
This should only be done by a competent person and only if the battery is safe to charge.
No.
The PC800 is designed to supply power only when correctly connected to a battery.
This spark-free safety feature prevents the charger from being used as a standalone power supply.
Calcium mode includes an Equalisation stage.
This stage uses constant current up to 16V and can take up to 12 hours. This is normal for calcium battery recovery.
Possible causes include:
Sulphated battery
Faulty cell
Battery at end of life
Parasitic drain in the vehicle
Load left connected during charging
Battery too large for selected charge rate
Load-test the battery before replacing the charger.
Possible cause:
Battery may be sulphated, deeply discharged or faulty.
Recommended action:
Initiate Rejuvenation mode. If the fault returns, the battery may need to be replaced.
Possible cause:
Clips are touching each other or connected incorrectly.
Recommended action:
Check the clips are not touching and confirm correct polarity.
Possible cause:
Bulk charging has stopped after 24 hours.
Recommended action:
Battery may be faulty or too large for the selected charge rate.
Possible cause:
The charger is too hot or airflow is restricted.
Recommended action:
Move the charger to a cooler location and check that the fan and vents are not blocked.
Possible cause:
Battery voltage did not rise as expected.
Recommended action:
Check the battery condition and remove any load from the battery.
