Ruvis Posted February 23, 2015 Report Share Posted February 23, 2015 Good day my fellow sound peeps. Not sure if I'm posting in the right thread.Sorry if I do!! Just a question.... I usually use the NP-F970 lithium batteries on my SRb receiver and it lasts a few days. Bought a NP-F550 today and just want to know what the average hours you guys get out of it?Or should I rather ask,at what voltage does the SRb switches off? Thank you in advance Quote Link to comment Share on other sites More sharing options...
LarryF Posted February 23, 2015 Report Share Posted February 23, 2015 Hi Ruvis, From the data sheet for the SRb on WWW.lectrosonics.com, the run time is "Typical runtime with a 7.2 V, 2200 mA “L” style battery is approximately 11 hours." If you have a battery with a different rating, you can take a ratio. Be aware (Beware) that most generic "replacement" batteries are usually junk and typically have less than half their rated capacity. The SRb will run from the battery until the protection circuity in the battery shuts down, typically around 5.5 Volts.

osa Posted February 23, 2015 Report Share Posted February 23, 2015 Mine usually last 5-6 hrs per full charge continuous. Easily a full day if you manage your on/off times -Ken Quote Link to comment Share on other sites More sharing options...
al mcguire Posted February 23, 2015 Report Share Posted February 23, 2015 I swap mine out at lunch. More reliable method than expecting camera op to notice no audio signal. Quote Link to comment Share on other sites More sharing options...
Derek H Posted February 23, 2015 Report Share Posted February 23, 2015 I get 10-11 hours, which is amazing for such a small pack. Buy three and you're set for life. Quote Link to comment Share on other sites More sharing options...
Ruvis Posted February 23, 2015 Author Report Share Posted February 23, 2015 Thank you so much guys,I really appreciate all the input. Will keep an eagle eye on it,with my 970's as backup. Thank you again Quote Link to comment Share on other sites More sharing options...
Nathaniel Robinson Posted February 23, 2015 Report Share Posted February 23, 2015 Yup, making it to lunch easily with my knockoffs (DSTE brand on Amazon). Camera seems to grumble less than when using the NPF970. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...

Sent from my iPhone using Tapatalk I ordered a NP-40 battery rated at 1400 mAh. Will test when it gets here Friday and see how it does. DTSE seems to have an extensive line. If it doesn't make at least 700 mAh, Amazon will get it back. Best, Larry F Lectro Quote Link to comment Share on other sites More sharing options...
Ruvis Posted February 23, 2015 Author Report Share Posted February 23, 2015 That's exactly why I've ordered the 550 Nathaniel.I have to do a velcro job on the SRb onto camera.So less strain on velcro.Keep you guys posted. Thank you all for the reply,you guys rock!! Quote Link to comment Share on other sites More sharing options...
