I bought this battery as a replacement for a defective battery in a GPS receiver from Q-Starz because it should be identical, according to Internet. In the battery provided herein applies absolutely to the both of the dimensions, such as, from the terminals and also of the electrical values The shroud is indeed ultimately not big important but affects quality than the original, and ev. Says yes also about the overall quality. Anyway, working again my GPS receiver and both charging as discharge times are the same as the original (as long as it was a safe place).
