    Posted by John on 18th Oct 2016

    I just bought the new TN42. It's massive head gives an indication of the power it has ! These 18650 batteries are the best way to power this beast.

    I have a tn12 that I use at work every day and I only need to charge these batteries once every few weeks. They charge quickly and they hold a charge very well.
