Car Battery Charger
OPTIMATE AUTOMOTIVE BATTERY CHARGERS
The OptiMate High Performance Battery Charger lineup has the perfect battery charger for every car fitted with either a Pb (lead-acid) battery or an advanced & lighter LiFePO4 (Lithium LFP) starter battery. EV vehicles (Tesla, Porsche Taycan, Hyundai IONIQ/KONA etc.) also have a 12V auxiliary battery (Pb or LFP) that requires charging & maintenance when the vehicle is stored and the main battery is not under charge, or if the main battery is charged at low power.
All OptiMate battery chargers share the following key features:
AUTOMATIC – OptiMate battery chargers are fully automatic after you connect to the battery. Your OptiMate automatically diagnoses the battery’s condition and will then save, charge and maintain as needed. No supervision required! |
24-7 SAFE MAINTENANCE – OptiMate battery chargers are safe to be left connected for a weeks or months. The battery is tested hourly and receives maintenance (float) charge only if needed. Connect & forget for MORE battery power and LONGER battery life! |
LOWER POWER USAGE – OptiMate battery chargers are energy efficient certified. OptiMate’s advanced electronic technology reduces electricity usage and saves you money. |
TWO ACCESSORIES – All OptiMate battery chargers include 2 separate accessories as standard, a set of battery clips and a fused battery lead / harness with ring connectors that can be installed on the vehicle. |
AMPMATIC – standard in all chargers that deliver 6 Amps and higher; charge current is automatically adapted to match battery size and condition – a smaller battery gets less, a larger battery gets more! |
TEMPERATURE REGULATION – OptiMate 6 and 7 series for lead-acid batteries adjust charge voltage match ambient temperature – higher when colder, lower when hotter! OptiMate Lithium battery chargers protects lithium batteries sensitive to extreme temperatures, by reducing charge current below 0°C (32°F) and above 45°C (113°F) and interrupting charge below -20°C (-4°F) & above 55°C (131°F). |
POWERSUPPLY / TUNE MODE – Stable 13.6V power that provide the best environment to troubleshoot an electrical fault, upload a new ignition map or set up electronic modes and personal vehicle settings, without fear that the battery may run flat when the engine is not running. |

General Automotive FAQ
1) We use less AC power, so we are more efficient when it comes to the power you pay for. If the battery charger doesn't have power factor correction it means you are using only parts of the AC wave to generate output power. As your output need is the same it means when you use part of the wave the current is higher, you have very high peaks of current that average to a higher level. OptiMate uses the complete wave to generate power, so it is always low.
2) After initial charge mode selection, we are the only charger that is 100% automatic. A selection made remains in memory after the battery is disconnected and AC power is lost (until the user decides to charge a different type of battery).
3) The OptiMate is the only charger that has an Ampmatic charge program - the output current automatically adjusts to match the battery size - a smaller battery automatically gets less, a bigger battery more. Current automatically varies between 1A and 10A (i.e. 2, 3, 4, 5 etc.) depending on the battery size and condition.
4) What also makes us stand out is the 24-7 maintenance mode of the charger: During every hour 30 minutes rest and 30 minutes charging if needed. Checks every hour if the battery has lost charge and will deliver charge for 30 minutes. Refresh - Will immediately return to charge if sensed that the battery has been used and needs high current charge.
