Projecta 21 amp 6 Stage Charger
$299.00
6 Stage Charging
6-stage charging is ideal for use on a wide range of battery types including automotive and marine as well as deep cycle batteries commonly found in boats, caravans and other recreational vehicles.
6-stage charging uses sophisticated electronic monitoring to ensure a faster, comprehensive and professional style charge giving your battery longer life and better performance compared to using traditional chargers.
Calcium Mode
Pro-Charge is designed to charge traditional lead antimony as well as modern calcium batteries. Calcium mode adjusts the charging profile to suit calcium batteries, and is best suited for calcium batteries that have been deeply discharged and require an equalisation charge to restore a full electrolyte reading.
Adjustable Current
Suitable for a wide range of different size batteries, Pro-Charge battery chargers feature an adjustable output that can be set as low as 1A to deliver optimum and safe charging for all your batteries.
Rejuvenation
Pro-Charge's rejuvenation mode can restore tired batteries by breaking down sulphation and revitalising the battery cells, increasing battery life and performance. This mode is optional and runs for a full 24 hours and is ideal for periodic maintenance.
Safe & Easy
Fully automatic and spark-free, Pro-Charge is short circuit and polarity protected, safe to use on batteries still connected to the vehicle and can be left connected indefinitely without risk of overcharging. Pro-Charge features user-friendly controls and remembers the last settings used even after the power has been turned off. A mounting kit is included for permanent installation.

Know before you buy
Before you buy a battery set-up
A second battery runs your fridge, lights and charging without touching the starting battery. Modern vehicles and lithium batteries change how that system should be built.
- Smart alternators
Many late-model vehicles have smart alternators that vary their voltage. A simple isolator doesn't charge a second battery well from these, so a DC-DC charger is recommended (Redarc).
- Where lithium can go
Lithium batteries must not go in the engine bay: the heat is too much (Redarc, Enerdrive). They go in the cabin, tub or canopy.
- Charge it correctly
Lithium needs a charger with a lithium profile, and most can't be charged below 0 C unless the battery is heated. Don't mix battery brands or sizes in one system (Redarc).
- Sizing solar
Work out how many watt-hours you use a day and divide by 5 to 6 sun hours to size your panels. A panel laid flat can lose up to 38% of its output (Enerdrive).
Common questions
Do I need a DC-DC charger?
If your vehicle has a smart alternator, yes: isolators charge poorly from them. A DC-DC charger also gives the second battery the right charging profile, including for lithium (Redarc).
Can a lithium battery go under the bonnet?
No. Battery makers say lithium batteries can't handle engine bay heat and must not be installed there (Redarc, Enerdrive).
Lithium or AGM?
Lithium needs a charger with a lithium profile, a location out of the engine bay and, below 0 C, a heated battery to charge. Compare usable capacity and weight on each battery's specifications, and follow its maker's mounting guidance.
How much solar do I need for a fridge?
Add up your daily use in watt-hours, then divide by 5 to 6 sun hours (Redarc). Allow extra if the panel will lie flat or sit in shade.
Can I run my fridge off the starting battery?
You can, but you risk a flat battery and no start. A second battery with a DC-DC charger keeps the starting battery for the engine.
