Verified Customer Reviews for TecMate OptiMate DC to DC Battery Optimiser (SAE)
Problem solved
31 Oct 2025 by Spencer M
This is a great product for trickle charging a motorbike battery is a garage with no power supply. Really easy to use and good instructions (although easier to watch on YouTube ) Just hook up to a larger battery and then connect to the motorbike battery. I used the O Rings. No need to jump start the motorbike anymore!

My garage is separate from my house so has no power. Purchased previous model 6 years ago for my Mille - never had a problem starting in all that time. New RSV4 Factory was delivered last week so had to buy another. Both coupled to a Leisure Battery which also powers the lights. Great solution to my problem.
