When you receive your order from us your new batteries will be almost fully charged but you will still need to complete the charge before first use, the charge time will depend on your charger, just leave it on until it indicates its finished, you might just want to fit them and use, but that would be unwise, missing out on charging them first could shorten overall life expectancy
It's not always apparent but it will take up to ten charges combined with use in your device before a full capacity charge can be achieved, this is the normal part of conditioning, letting the batteries sit in a discharged state, even partially is not a good idea, as soon as you have used them put them back on charge, never try to discharge the batteries, with this type of technology it will only mean a shorter life, these batteries need to be kept charged, so if there is any reason where they are not be used then ensure they are charged beforehand and then every 4-weeks, but do not leave on a charger for more than 24-hours
