Projecta AC015
Charge N’ Maintain Battery Charger
12V 1.5A 4 Stage Switchmode Battery Charger
The Projecta AC015 is a compact 12V 1.5A automatic battery charger designed for maintaining small to medium 12V batteries.
It uses 4-stage automatic charging to safely charge and maintain the battery. Once the battery is fully charged, the charger moves into float mode and can remain connected to maintain the battery.
The AC015 is suitable for 12V automotive, marine and LiFePO4 batteries within the rated battery range.
The AC015 includes:
4-stage automatic charging
Battery health check
Bulk charging
Absorption charging
Float maintenance charging
Switchmode technology
Spark-free protection
Reverse polarity protection
IP65 weatherproof rating
LED charge indicator
Fused wiring harness or battery clips
Mounting bracket and 3m extension lead
The AC015 is designed for 12V rechargeable batteries only.
The manual states it is suitable for most 12V automotive, marine and lithium batteries.
The AC015 is intended for maintenance charging of small to medium batteries.
Battery range:
Automotive: 200–650CCA
Marine: 250–700MCA
Lithium LiFePO4: 1–15Ah
No.
The AC015 is a 12V battery charger only.
Do not use it on 6V or 24V batteries.
The AC015 uses a 4-stage charging process:
Battery Health Check — Checks that the battery can accept charge.
Bulk — Charges at maximum current up to the set voltage.
Absorption — Charges the battery to 100% using constant voltage.
Float — Maintains the battery at full charge without overcharging.
Yes.
Once fully charged, the charger enters float mode and can remain connected to maintain the battery.
For permanent hard-wired installations, if the vehicle will not be used for some time, it is recommended to leave the charger connected to mains power so it can maintain the battery.
Before using the AC015:
Read the instruction manual.
Use 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, leaking 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 AC015 can be hard wired using the supplied fused wiring harness.
For AC015, use a 3A fuse.
Connection:
Any modification to the 240V mains lead must be carried out by a qualified person.
The LED indicator shows the charger status.
Green flashing — Charging
Green solid — Fully charged / float mode
Yellow — Fault condition
The charger will show the full / charged indication.
A battery hydrometer can also be used on serviceable lead acid batteries. A reading of 1.250 or more in each cell indicates a fully charged battery.
Check the following:
Battery voltage is above the minimum start voltage.
Battery connections are clean and secure.
Red lead is connected to positive +.
Black lead is connected to negative – or correct chassis earth.
The 240V mains outlet is switched ON.
The battery is not frozen, damaged or faulty.
The AC015 is designed to start charging from 2.0V. If the battery voltage is lower than 2.0V, the charger may not start.
If the battery is below 2.0V, the charger may not detect it.
The manual advises that booster cables can be used between two batteries to provide more than 2.0V 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.
A yellow fault indication can be caused by:
Reverse polarity
Poor battery connection
Battery voltage too low
Faulty battery
Battery unable to accept charge
Check the battery leads, polarity and battery condition.
No.
The AC015 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.
The battery may not be holding charge.
Possible causes include:
Sulphated battery
Faulty cell
Battery at end of life
Parasitic drain in the vehicle
Accessory or load left ON
Load-test the battery before replacing the charger.
