NASA MSL Mission Update
Today, Curiosity's two lithium ion rechargeable batteries are being recharged to 100 percent of capacity in preparation for entry, descent and landing.
The batteries, which have been maintained at a 70-percent state of charge during the cruise to Mars, are being recharged using power from Mars Science Laboratory's cruise-stage solar array.
The batteries enable Curiosity's power subsystem to meet peak power demands of rover activities when the demand temporarily exceeds the onboard multi-mission radioisotope thermoelectric generator (MMRTG) steady output level.
With a capacity of about 42 amp-hours each, the batteries are expected to go through multiple charge-discharge cycles per Martian day.
