4AH Vanon battery bought over 4 years ago as spare for Bosch drill
Bought a 4AH Vanon battery as spare for my Bosch hammer drill kit over 4 years ago. It has, so far, been reliable and lasts as long as expected between charges - in fact I don't recall it ever going flat in typical 'handyman' use. A few weeks ago one of my sons borrowed the drill + battery to replace over 1000 (1200?) roofing screws in his house. He did not take the OEM Bosch 8Ah battery (it would have required special permission to transport by air) so the Vanon was the only battery he had. He used it for about 12 hours over two days, and was highly impressed. I assume he charged it whenever he had a break, but, as far as I am aware, it never let him down - and he is young, strong, fit and didn't let up - gave it as good a work-out as anyone might. And this was a 4 year old battery. Stark contrast to most of the other reviews! The 'date of experience' below is misleading: May 2019 to today, and my son used it a few weeks ago.
