How long will Bescor MM7XLRATM Starved Eloctrolyte battery last at DVinfo.net

Rafal Krolik · August 6th, 2004, 12:07 PM

I am looking at ordering the Bescor KIT from B&H. Here is the link.
My question is if any of you know how long will the battery included with the kit last. So far I have not been able to find any reference regarding this issue.

Thanks in advance.

I have an older 50W Bescor woth the MM7 battery (now only used as back up) and that battery will run about 75-90 minutes on a constant run. Generally I use the light with a Bescor battery belt and get about 2 1/2 hours out of it which is in most cases enough for the typical wedding reception I do but it's nice to know the other battery is there just in case. With the dimmable light I would guess the run time will go up depending on the wattage you set the light for but I would be surprised if you could get more than 2 hours out of the battery even with the light at the lowest setting.
Now, having said all that, I will say that other than the weight of the battery belt the light works great and I've had the light and both batteries for almost 3 years and it gets used on a weekly basis and sometimes more. The big challenge is doing a saturday and sunday gig and having to charge the battery to full in that short a time but it's never failed me yet.

Thanks Don. Judging from what you said, this doesn't sound too bad, especially that I saw these batteries for about $80. I guess if I get the kit and two extra batteries I should be good to go. What is the charging time if you don't mind me asking?

The MM7 battery usually takes about 12 hours or maybe a little more. Remember these are lead acid type batteries just like a car battery so they take longer to charge. I have 2 chargers and they have the red light to indicate when the charging is complete. Don't remember the model number right off hand but you want to try to always keep the battery from running completely down as that can damage the battery. Anyway,hope that helps a little,
