OptiMate 4 Dual Program 12V Motorcycle Automatic Battery Charger Optimiser

Product Information

Or, if you want to set it and forget it, you can practically do that, too. Assuming the battery and vehicle electrical system are good, the Optimate 4 will at least charge and maintain a battery with or without your knowing what it’s thinking. The Tecmate Optimate 4 Dual Program is a battery charger designed for a range of 12V lead-acid batteries. The device can be used to maintain and charge all types of batteries, including AGM, GEL, and STD. The charger comes with two separate programs, one for direct charging and the other for maintenance. This ensures that the battery remains in top condition at all times. The charger also has a unique feature that allows it to automatically diagnose the battery's condition and adjust the charging process accordingly. This feature can help extend the life of the battery and avoid damaging it due to overcharging or undercharging.

Considering that the Optimate 4 appears well designed and is priced within range of competitive brands, we think it’s worth considering. It should at least do what other smart chargers also claim to be able to do, if not also a few things more.For all 12V power sport battery types including lead-acid (Pb) > STD (with filler caps), AGM & GEL (sealed VRLA) ) and Li-Ion made with LiFePO4 / LFP technology. The alternating test and charge maintenance program is designed to provide the recommend maintenance voltage for AGM / GEL batteries whilst reducing the average voltage as required by STD filler cap batteries, making it ideal for indefinite and 100% safe long term maintenance charging of any type of 12V lead-acid battery. Technical Specifications Multi stage charging – bulk, pulse absorption, cell balancing ensures each cell in the battery performs at maximum. Assuming the battery is disconnected from a vehicle, and the Optimate 4 sees the battery as deeply discharged, it will use one of two desulfating modes indicated by the orange #3 LED.

Will this optimiser work with a BMW R18 and what is the right cable option to chargeit? January 17, 2023How smart is it? It’s so smart, that if they gave out degrees to consumer battery chargers, some might say this one should have a PhD. It’s so transcendently gifted, in fact, it can even raise the dead!

Bulk charge stage: Charges at 0.8 Amps constant current until such time as the battery is normally able to crank the engine. The automatic multi stage program engages as soon as the OptiMate is connected to a 12V battery that has at least 2V. So I leave you with mixed feelings on the Optimate 4. There’s nothing at all wrong with it, it seems very well made and solid and I like the quality of the hardware and connectors it is supplied with. The Optimate 4 works, it has a lot of lights, a two year warranty, and many different types of accessory harnesses. It’s been “Recommended by 8 major powersport manufacturers”, according to Tecmate.This will be fine to use on your Honda, unless you have a Lithium battery fitted, in which case you would require a Lithium specificcharger. The Optimate4 did not revive either and in the case of the motorcycle battery, reported it as good and charged but it was not. Repeated cycles of charging (as suggested by their documentation) yielded no improvement. It gave up on the deeply sulfated battery. Three (3) near new (12.5 + volts) lead acid wet cell 7 ah to 24 ah batteries went through all the charger cycles and both green lights lit continuously indicating the charger had completed it’s full range of tests and charging sequences. When the ground signal can’t find a good path to ground, you can get all sorts of strange electronic burn-out issues, especially if there are 230 volt devices on an uninsulated (grounded) floor, such as ovens & electric water-heaters.”
