Chargers
Chargers by battery type
Use the right charger and mode for your battery: AGM, EFB, lead-acid, lithium, leisure, and gel. Wrong voltage or profile can damage the battery.
Your battery type dictates which charger and which mode to use. AGM (Absorbent Glass Mat) batteries—common in Start/Stop and modern cars and vans—need a charger with an AGM mode or profile; wrong voltage or a lead-acid-only setting can undercharge or overcharge them and shorten life. EFB (Enhanced Flooded Battery) batteries work with many smart chargers; some chargers offer a dedicated EFB mode for optimal charging. Standard flooded lead-acid batteries are the most forgiving and work with most conventional and smart chargers.
Lithium (LiFePO4) automotive batteries require a dedicated lithium charger; never use a lead-acid or AGM-only charger—it can overcharge the cells and create a safety risk. Leisure and deep-cycle batteries need a charger with a leisure/deep-cycle profile; gel batteries need a charger that limits voltage and does not use equalisation. If you are unsure of your battery type, check the label on the battery or use our Battery Type Picker; then choose a charger that explicitly supports that type.
Chargers for AGM Batteries
AGM batteries need chargers with an AGM mode or profile. Wrong voltage or charge algorithm can damage them.
Chargers for EFB Batteries
EFB batteries work with many smart chargers; some have a dedicated EFB mode for optimal charging.
Chargers for Lead-Acid Batteries
Standard flooded lead-acid batteries are compatible with most conventional and smart chargers.
Chargers for Lithium Batteries
Lithium automotive batteries require dedicated lithium chargers. Never use lead-acid or AGM-only chargers.
Chargers for Leisure Batteries
Leisure and deep-cycle batteries need chargers suited to deep-cycle charging profiles.
Chargers for Gel Batteries
Gel batteries need chargers that limit voltage to avoid damaging the gel electrolyte.
Not sure which battery you have?
Check the label on your battery for AGM, EFB, or standard. Use our Battery Type Picker or battery type detector (charger tools).
