Many registered nurses (RNs) and licensed practical nurses (LPNs) are finding the education and support they need to reenter nursing by enrolling in a refresher program. Offered through colleges and hospitals, nurse refresher programs are designed for RNs and LPNs who have been out of the field for at least three years. Whether your current nursing license is inactive or lapsed, your state board of nursing requires you to take a nurse refresher course to return to active status.
How to charge a battery. An average car battery has a capacity of around 48 amp hours which means that, fully charged, it delivers 1 amp for 48 hours, 2 amps for 24 hours, 8 amps for 6 hours and so on.
An amp hour (AH) is a rating usually found on deep cycle batteries. The standard rating is an Amp rating taken for 20 Hours. What this means, say for a 100 AH rated battery is this: Draw from the battery for 20 hours and it will provide a total of 100 amp-hours. That translates to about 5 amps an hour.
