 * The following open-circuit voltage curves have been extracted from the datasheets of the
 * listed battery parts. They will not be 100% correct for all batteries of the chemistry,
 * but should provide a good baseline. These curves will also be affected by ambient temperature
 * and discharge current.
 *
 * Each curve is 11 elements representing the OCV voltage in microvolts for each charge percentage
 * from 0% to 100% inclusive in 10% increments.
