Replacement/Spare battery pack for Cox Box & Megaphone
How to store your battery for long periods unused:
Our typical recommendation with these batteries is to store them with between 40-60% charge, leaving them off the charger and in a temperate climate. 40-60% are guidelines and it’s a little hard to tell with the Blue Ocean, but basically, you leave it on the charger until it gets to flashing green light, let it go for a little while longer and then take off.
*Fully charged or fully discharged or leaving it on the charger are things to try and avoid.
