Author Topic: Need info: Strong/Eprad CPA-10 battery Aaron Sisemore Flaming Ribs beat Reeses Peanut Butter Cups any day! Posts: 3061 From: Rockwall TX USA Registered: Sep 1999 posted 09-28-2002 03:54 PM                     I have one of three late 80's vintage Strong/Eprad CPA-10 autos that has completely gone to hell after its backup battery failed. Without driving three hours to the location just to figure out what type of battery I need (I am pretty sure its a cylindrical type lithium cell but not 100% sure- I will also need voltage and type number) I am hoping someone out there (Pat?) might know what I will need so that I can order a replacement ASAFP. The theatre is running all shows on that screen in manual mode at this time. Any help would be appreciated. -Aaron  |  IP: Logged Rick Long Jedi Master Film Handler Posts: 759 From: Toronto, Ontario, Canada Registered: Nov 1999 posted 09-28-2002 04:37 PM                     My manual claims that this is a "Size 1/2 AA 3.6V). Hope that helps. I usually warn customers NOT to shut off the automation power at night if they get a low battery warning, and to change the battery with the automation power ON.  |  IP: Logged Richard Fowler Film God Posts: 2392 From: Ft.

We found that soldering the battery leads to the PCB cured it in every case. I'm assuming that contacts on the PCB oxidise after a while.  |  IP: Logged
