This rechargeable battery is a replacement for the Varta 55630101501 & CP300H.
Had been looking all over in big box stores, popular chain stores and even battery specialty stores for this rather obscure battery to no avail for the better part of two years. Was just on the verge of throwing out the flashlight for which I needed it when I got he bright idea to look for it on the internet. I mean, everything's on the web, right? What had I been thinking? Was pleasantly surprised to find the item at Battery Mart and even more pleased at the reasonable price and ease of ordering it. The battery came well packaged and quicker than expected and has worked perfectly. No issues, but greatly appreciative of the company's responsiveness and courteous in following up to ensure that I'm satisfied with my purchase. Will definitely be returning as a customer.
