Great Batteries
Saturday, 4 April 2020  | 

I recently purchased a Nightcore charger so got these to go with it and use on my bike light. The batteries that I were using were cheap and only lasted about 8 hours on full beam but these Nightcore's last double the time.

Ordered batteries and charger for a torch I had bought ( for a winter trip to Swedish Lapland) unfortunately did not realise that I could not buy batteries and charger at local shops so torch was not taken on trip. Ordered from you on my return, items work well and were rapidly delivered. Shame I was not in the know before my trip. Thanks for the items and service.
