To be fair mate, dont take no notice its a simple mistake, not all manufacturers supply a product as good and reliable as planet eclipse!
To be honest with you i fully stripped, changed every single o ring, lubed and serviced a whole marker, tried 3 bottles and 2 batterys then just about bounced a ego off the floor before a guy put a old half used battery in it for me and it worked spot on!
It happens! Trust Eclipse, dont trust a billion £ company like xyz (i will refrain from typing battery manufacturers names) lol
