Hi I use a couple of fans that run costatly when the utility power is available, the air sweep is hgh enough to prevent any Hydrogen build up. One fan alone is enough in case one fails. Also have several other repeaters in with me that have deep cycle batteries in the cabinet with no venting. Not been a problem, well so far any way.

I have room in the bottom of the cabinet for a couple of batteries. I know If I want to have them in the cabinet then i need to look at AGM type so I don't have to worry about venting & spillage. I can fit 2 120AH AGM batteries in the bottom of the rack, so that's my plan for permanent installation. However, there are "insufficent funds" available to purchase those right now. I do however have a Marine Deep Cycle 120AH battery at my disposal I could use for the time being. It would give me some run time in a power failure. I know that it could not be in the radio cabinet due to the hydrogen venting. My question for the group: Is there a way I can install this for the time being safely? The repeater is in the base of a large water tower that is far from airtight but still enclosed. How much venting would be required? Do I need to vent it outdoors for one battery? Is this a bad idea & I should just wait until I can get the AGM batteries I need? Thank you for any replies. I know we have covered some of this before but searching the archives failed to yield the answer I'm looking for. Tom W9SRV ------------------------------------ Yahoo! Groups Links
