The NOCO GENIUS5 is our top pick because its listing states a 5A output for 6-volt and 12-volt lead-acid and lithium-ion (LiFePO4) batteries, a 72-inch AC cable, an 80-inch DC cable with battery clamps and a 3-year warranty. For a 12V/24V charger, the EAFC lists 20A at 12V, LiFePO4 support and a 2-year warranty; for maintenance charging, the MOTOPOWER MP00205A lists an 800mA output with SAE quick release leads.
This guide compares six car battery chargers from NOCO, PROFIKLA, MOTOPOWER, EAFC, Aptliton and HAUSPROFI, using what each listing states: charging current, battery voltage, battery types, capacity range, protections and warranty. Stated 12V charging currents run from 800mA on the MOTOPOWER to 20A on the EAFC.

Our process
How do we choose our picks?
We don’t lab-test products ourselves. Instead we synthesise current Amazon UK listings and published specs into clear, honest recommendations. We earn a commission if you buy through our links, but that never changes which products we rank.
Current UK availability
We check each pick against live Amazon UK catalogue data rather than last year’s model lists. Stock moves fast, so a listing can sell out after we publish.
Published specs
We compare manufacturer specifications so each pick is right for a real budget and use-case.
UK-specific fit
We factor in UK voltage and plug/fitting standards — details that generic global lists miss.

Editor's Note
Four of these six listings state battery capacities in Ah (PROFIKLA, HAUSPROFI, Aptliton and MOTOPOWER); the NOCO and EAFC listings do not. Cable details are sparse: NOCO states a 72-inch AC cable and an 80-inch DC cable, EAFC a 2m power cord, and the other four give no cable length. None of the six states an IP rating, and the HAUSPROFI listing states no warranty term.
Our Take
As a default, the NOCO GENIUS5: 5A for 6-volt and 12-volt lead-acid and LiFePO4 batteries, stated cable lengths and a 3-year warranty, all on the listing. For a 12V/24V charger, the EAFC lists 20A at 12V and a 2-year warranty. For maintenance charging of a 12-volt lead-acid battery, the MOTOPOWER MP00205A lists 800mA and a 2 year manufacturer warranty.
Questions & answers
Frequently asked questions
How many amps does a car battery charger need?
The listings here state outputs from 800mA to 20A and tie them to battery size in different ways. MOTOPOWER says its 800mA unit quickly charges motorcycle batteries up to 30Ah and slowly charges car batteries up to 80Ah. PROFIKLA and HAUSPROFI list 8A at 12V for batteries of 6Ah-150Ah, and Aptliton lists a 15A/8A charger for 12V/24V batteries of 2-200Ah.
Can a car battery charger be left connected for long periods?
Several listings describe a maintenance mode. NOCO says its charger constantly monitors the battery so it can be left connected indefinitely; EAFC says its charger switches to a float/trickle maintenance mode once the battery is fully charged; MOTOPOWER says its unit maintains the battery at 13.6V; Aptliton lists a maintenance mode for long-term charging. These are the brands' own statements.
Do car battery chargers work with lithium (LiFePO4) batteries?
Three of these listings say so: NOCO names lithium-ion (LiFePO4) alongside lead-acid, and EAFC and Aptliton name LiFePO4. The PROFIKLA, MOTOPOWER and HAUSPROFI listings name lead-acid battery types and do not mention lithium.
Which car battery chargers work with 24V batteries?
The PROFIKLA, EAFC, Aptliton and HAUSPROFI listings state 12V and 24V. The NOCO listing covers 6-volt and 12-volt batteries, and the MOTOPOWER listing 12-volt batteries.
Can a battery charger recover a flat or dead battery?
The listings set different limits. NOCO says the GENIUS5 charges batteries from as low as 1 volt and has a Force Mode for completely dead batteries down to zero volts; Aptliton lists a repair function for deeply discharged batteries (from 0.3V). EAFC says its Pulse Repair cannot revive completely dead batteries or repair physically damaged ones, HAUSPROFI says its repair mode cannot activate a dead battery, and MOTOPOWER says batteries with cellular problems may not charge.
What warranty do car battery chargers come with?
On these listings: a 3-year warranty on the NOCO GENIUS5, 2 years on the MOTOPOWER MP00205A and the EAFC, 12 months on the PROFIKLA and 1 year on the Aptliton. The HAUSPROFI listing states no warranty term.
