Q: 1. Will this run a Sony camera? Some non-Sony batteries do not.

A: If the Sony camera takes NP-F batteries, the Sound Devices XL-B3 Lithium Ion Battery should be compatible, as it is an NP-F-type battery.

Q: 2. What have people found is an average charge time using the Sound Devices L-series Battery Charger?

A: In general, charging times vary greatly for it depends on the amount of discharge, the charger and things like ambient temperature. With a fully discharged battery you should minimally consider 1-2 hours, maybe 3-4. In time you will get a feel of how long. Keep in mind generally when a battery takes longer to charge it will work longer. Generally batteries that charge from a fully depleted state in a few minutes last only a few minutes. That is because they are at end of life since the chemicals inside are exhausted and thus the battery will accept only a small charge.
