Secondly and most importantly, make sure you charge until full after every use, a fully charged battery will keep that full charge for a good couple of weeks so no need to recharge if it’s not in use for a week. To begin with, fully charge upon delivery and before first use until they are full (should be no more than a few hours), it doesn’t take very long as we ensure our batteries are kept at a high charge.
