Typical Niterider, customer no service when you have a problem.. They will of course try to convince you to buy another battery at more expense to you.. Spend 90.00 and get a Magicshine.. When NR was the only game in town I spent lots of $$$ with them and whenever I had a problem, they could care less..

Had a similar issue with a NR12E that would not hold a charge, sent the light back to them 2 times and each time they said it's working fine for us.. When I would fire it up, it would work fine for 30 minutes and then drop into reserve.. There solution was for me to buy a $200.00 battery..
