Power Chargers

OPTIMATE POWER 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.
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. |
CHOOSING THE RIGHT CHARGER
OptiMate power chargers are arranged in 3 groups, EASY, MORE and BEST, according to the vehicle owner’s battery knowledge and functions demanded from their battery charger.

The EASY group includes all OptiMate battery chargers that automatically adapt to your battery’s condition and will start charging automatically, no need to select anything.
Function – To charge & maintain a stored vehicle’s 12V battery.
Popular – with vehicle owners that want easy ‘connect and forget’ battery maintenance.
OptiMate 5 Start-Stop, a popular choice for car/automotive vehicles with modern electronic systems (e.g. start-stop system, GPS tracking / web connect), offer a higher charge current of 4 Amps and 24-7 maintenance.
If you store your vehicle outside, OptiMate SOLAR CAR KITS offer easy in-cabin maintenance charging in 2 STEPS: 1) Position the solar panel inside the vehicle, 2) Connect the controller to the OBDII connector of the vehicle. The rest is automatic; the battery is maintained daily.
OptiMate Solar 10W CAR KIT is ideal for smaller vehicle batteries (< 2000cc).
OptiMate Solar 20W CAR KIT is ideal for medium to large vehicle batteries (> 2000cc).
OptiMate Solar technology delivers charge even in cloudy conditions. Learn more about how our OptiMate Solar Battery Chargers work: https://optimate1.com/solar

The MORE group of battery chargers offer additional features; they can SAVE a battery from dead-flat, and will then test, charge and maintain the battery.
Function – Save, charge, test and maintain any Pb – lead-acid – battery (STD/flooded, VRLA AGM or GEL).
Popular – with vehicle owners that know their vehicle’s battery’s voltage and may need to recover a ‘deadflat’ battery and then test its state of health.
OptiMate 5 SELECT charge 12V batteries and have an option for the 6V battery in classic car / old-timer vehicles or the 6V deep-cycle battery in an American RV.
OptiMate 6 Ampmatic is a popular choice for medium to large 12V automotive batteries. No need to make a selection, just connect to the battery and the charger does the rest. OptiMate 6 includes temperature regulation that ensures your battery gets the right charge in any temperature.
The BEST group of battery chargers offer most features and are battery chemistry specific (Pb or LFP), subsequently they can SAVE a battery from dead-flat, and will then test, charge and maintain the battery.
Function – Save, charge, test and maintain a 12V Pb (lead-acid: STD/flooded, VRLA AGM or GEL), OR, Reset the BMS and save, charge, test and maintain a 12V/12.8V/13.2V or 16V LFP Lithium-Ion battery.
Popular – with vehicle owners that know their vehicle’s battery’s voltage and chemistry type and may need to recover a ‘deadflat’ battery and then test its state of health.
GOLD – ADVANCED
The Gold battery charger series is packed with the most advanced OptiMate technology & programs that matches a premium battery’s specific charge requirement.
Select the right charge program for your battery (only once, selection remains in memory even if power fails), connect to the battery and the rest is fully automatic. Your Gold series charger’s advanced program includes a two-step desulphation save mode, a temperature regulated Ampmatic program that optimizes charge exactly to the battery’s requirement, advanced state of health testing followed by OptiMate’s unique and 100% safe 24-7 maintenance.
OptiMate 7 Select offers STD and AGM charge profiles for a faster recharge of automotive / truck engine start batteries. The power supply / battery support mode offer a fixed 13.6V for troubleshooting or show room support.
Lithium series battery chargers are the ‘expert’ choice if your high-performance car is fitted with a Lithium Ferrous Phosphate (LFP / LiFePO4) starter or auxiliary battery.
LITHIUM – EXPERT
OptiMate has been leading the industry of Lithium starter battery knowledge since its inception (2007-2008) focusing on Lithium battery care and longevity with the latest technology. A Lithium battery requires a charge program that is completely the opposite of a lead-acid battery when deep discharged, it needs to be delicately and precisely brought up to its normal voltage range before it can accept high current again.

OptiMate Lithium series chargers include Ampmatic current adjusting technology, low voltage pulse recovery from 0.5V, state of health testing, temperature compensation and active BMS (battery management system) reset for advanced Lithium batteries that have a built-in protection system for deep discharge or over charge.
OptiMate Lithium 4s 10A is for 4-cell-in-series 12.8V (4 x 3.2V) LFP batteries. The TUNE mode offers fixed voltage (13.6V) battery support during troubleshooting.
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.
We recommend our OptiMate 5 Start/Stop to charge and maintain your start/stop car.
Yes, the OptiMate is the perfect charger and maintainer for your car. The charger is ideal for 12V starter & deep cycle lead-acid (AGM, GEL, STD, EFB) batteries ranging from 12-160Ah.
PS mode is the Power Supply mode and it provides constant power for vehicle tuning, diagnostics and troubleshooting.
Yes, it is! That is exactly what the OptiMate is designed to do. The gentle charging algorithm will never overcharge or undercharge your battery.
