Battery runtime in Lectrosonic PDR

[jbuerjes]

 

I did a battery test with Lectrosonics PDR units (recording).
Eneloop black (rechargeable) = 4 hrs
Varta alkaline industrial (not rechargeable) = 2 hrs 15 min
Varta lithium ultra (not rechargeable) = 6 hrs 30 min

Thank you @jbuerjesfor posting this, will be running a PDR through its paces in cold weather for an upcoming shoot and these runtimes are super helpful.

@lazajamsonic I remember that the battery status indicator went down rather quickly in the first half of the runtime, but then it took it a longer time to reach the bottom. The rechargeables are best right out of the battery charger.

The NP-50 batteries will have a temporarily higher voltage right off the charger but that voltage falls quickly to a "normal" value. Li-ion batteries only lose 2% of their charge per month (!) unlike some  high capacity NiMh batteries that can lose 15% or more in a day after being fast charged. All this to say, you can charge a Li-Ion NP-50 and use it a week later with almost unmeasurable capacity loss.

Thank you for sharing.

for critical situations i use lithium aa cells with my audio Ltd A10, gives me with simultanious recording and transmitting minimum 8h

Tell me - if I use black eneloop pro - what should I set PRD - litium in the menu? The (not) second option in the settings is alkaline - there is no menu selection - `NI-MH
