OptiMate 4 Dual Program 12V Motorcycle Automatic Battery Charger Optimiser

Product Information

It also looks like the Optimate 4 will be released at the 2009 Indy Powersports Dealer Expo, and perhaps the Editor will give us a report from that show. Although I will admit that some features are nice to have, like the microprocessors in the Optimate and other battery chargers like those made by Battery Tender, Acumen and others. Hi, which Optimate would you recomend for a Triumph Tiger 800 xrx , the 3 or the 4? December 10, 2019

Bulk charge stage: Charges at 0.8 Amps constant current until such time as the battery is normally able to crank the engine. 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. Final battery float voltages never went above 13.3 to 13.5 volts vs. 14.0 to 14.5 volts needed to bring wet cell and AGM batteries to full charge.Various size and types of motorcycle batteries where connected to the OptiMate 4 over a two week period to test all OptiMate4 functions. They seem work just as well as the old-fashioned Battery Tender, but I’m wondering what the real difference is with some of them.

I just wish I could tell you that paying the extra money for one is worth it, but it’s beyond my abilities to tell.About 8 hours later, I went out into the garage and the green lights were on, so I assumed the process was complete. During the next 30 minutes the OptiMate offers the battery a supporting (and) maintaining charge, but only to the extent necessary to counter any losses or connected loads such as an electronic alarm or immobilizer. Overcharging and/or overheating of the battery is ruled out by this 50% duty cycle as the battery is interactively maintained for 30 minutes and then rests during the power drain tests of each alternative 30 minutes. So the battery is always 100% good to go, but never overcharged.
