  • Bought this as an addition to my 2Ah batteries, as I thought it would be better suited for the circular saw. Only difference is really the time to charge. The saw still cuts well enough on the 2Ah. I was worried about this shop, as I had never had of them, but they had the best prices for what I was looking for, so I decided to take a risk....and, this was the best risk I took. After placing order, I sent an email asking about delivery time, and shop responded to my question almost immediately!! Got delivery next day (less than 24 hours). Got some surprise gifts in my delivery: a 5m measuring tape + a marking pencil. Very good service. Would definitely use them again.

  • Great battery. The one plus system is excellent. I have a drill and nail gun and this battery gives we a much longer working time between charges. Excellent service and very fast delivery. I will be using you again. Keep doing what you are doing!
