What is a Replacement Battery? Please see the following document for information on what a replacement battery is.

Why should I choose a Cameron Sino Replacement / After Market Battery? Because Cameron Sino Batteries have better performance (higher capacity) and reliability (longevity and safety). This superior performance improves batteries’ running time, which is often better than the original brand replacement. This superior quality results in longer battery life and better protection of the powered device. All products are passed through a QA department which help Cameron Sino to achieve the lowest return rate in the industry.

Please be aware that the changes in the IATA regulations for batteries is impacting on some of our air consignments from overseas – apologies in advance if this affects your order.
