Have had two of these units fail recently after several years use. Examination indicated that the rechargeable battery had failed on both of them. Had difficulty finding an equivalent battery and phoned Horstmann to ask the part number; they refused to tell me, and said that the battery was not replaceable. They never asked who I was or what my trade status was, but said that the health and safety law forbids them from telling me the part number! When I asked them which particular law they were quoting, they hung up!
Have now replaced the batteries with the nearest equivalent that I could find and they are both working fine.
