Notes:
1
Output voltage of a fully charged, new battery pack is typically more than the
nominal values listed.
2
All of the charge delivered to the battery pack cannot actually be extracted by
the instrument. For a typical battery pack, Sea-Bird recommends assuming
that 75% of the delivered charge is available to power the instrument
For example, for a 12-cell battery pack:
75% * 550 KJ charge delivered = 412 KJ charge available.
Converting, 412 KJ = 8 Amp-hours (see Note 3 for conversion).
If you note during charging that the battery pack temperature rises above
45 °C, we recommend derating the battery pack capacity to 70% of the
delivered charge.

Battery capacity is historically measured in Amp-hours. New technology
makes it convenient to measure capacity in Kilo-Joules, which is a more
accurate indication of battery charge. The following formulas provide a
nominal conversion between Kilo-Joules and Amp-hours:
Amp-hours = Kilo-Joules * 1000 / (3600 * Battery Voltage)
Kilo-Joules = Amp-hours * 3600 * Battery Voltage / 1000
