I switched over my 2008 Touring from OEM cells to Cylinder cells, marketed by NewPriusBatteries . Since the prizmatic batteries are nominal 7.2 Volts, I was curious what the best 'load' would be for the reconditioning process. Headlight lamps don't make sense to me, since they are a higher voltage than the source battery. Does anyone think that a 6V 'Lantern' type bulb would make a reliable, steady resistance for a 7 V source? Thank you.
