“Just I was about to replace my 1 year+ AGM battery, decided to give the nanopulser a try.

Before the nanopulser, for the past few months no matter how I charge, it is harder and harder to get beyond 12.2V. with the nanopulser installed, first noticed is the car response is smoother and sharper but still rather still unsatisfactory as the voltage still hovering around 12.5 max when engine off.

Give Ian a ring and he mentioned AGM should be charge with a higher voltage between 15-15.5V and he voluntary loan me a charger, somemore deliver to my doorstep. It been 2 weeks since returning the charger, and the voltage stays around 12.8-13V when engine off.

Thumb up for the great service and good product.”
