| 193817 | 2003-11-22 07:04:00 | With Computers you have a CMOS battery for time etc, with digital cameras one of the setting up jobs is setting the date/time, am I correct in assuming that there is a built in battery which keeps the clock running when you take out the main rechargable batteries for recharging. Is this built in battery kept charged up by the main batteries or is it non rechargable and going to have to be replaced after 3 or 4 years or more similar to a CMOS battery?. | FrankS (257) | ||
| 193818 | 2003-11-22 10:14:00 | Its more likely to be a "supercap" which is a high capacity condenser (typically 1 Farad) that will hold a charge for many days and power the miniscule drain of the basic real-time-clock function. These would replenish from the camera batteries. You may find you need to reset the date/time if the batteries are out for a few weeks. One older camera here uses a lithium battery just like a PC does, in a slot accessible from the outside. |
