Battery life mostly comes down to how often you are willing to recharge a bike radar between rides. The middle range, covering most of the models tracked here, suits regular riding without a daily recharge. Units with the longest battery life are less common in this lineup but tend to rate the highest, while the shortest battery life range rates the lowest overall. Pick first based on how long you actually ride between charges, then compare price within that range.
