Does DEKA make a good UPS battery?

'Wow! Landy, a treasure house of info and links. Thank you. A lot of time has passed. I decided to go with 400 watt rather than 350 watt power supplies. The cheap-o-watt units have increased in price by 50%. ........the fan on the Mega is marginal at best, but for overall outside air circulation meaning for cooling the optional heatsinks and and presenting the coolest air possible to the bottom of the Megawatts, I decided to go with a brushless, ball-bearing 120 volt fan. This is a 3-1/2" inch square fan and cannot be operated unless it is anchored because it will attempt to slide or fly. Your idea of flanging a fan into the lid is truly clever given their performance ratings. I want to keep those bipolar transistor junctions as unwarm as possible. The bottom Mega is a full half inch off the deck of the cabinet. The large 120vac fan is going to present a lot of the "coolest available air" to the Mega's register slots. There is a lot of overhead room for Megawatt exhaust air to rise. The upper unit is set to exhaust directly onto the ammeter shunt. Sounds overboard but with a 100 amp hour battery paralleled with a 180-amp hour battery things can get warm fast. This is going to be my "at home" Bi-PAP and LED lights for night, setup. Quicksilver has a 500-watt Window AC unit in the bedroom, but with almost nightly power outages, it is simpler for me to stay in the umbilical "house" mainly for restroom convenience. Establishing power means hiking 100 meters to the battery generator shed, and starting the Kubota. I've got to do "something" this year about running gen power (soil is almost solid rock) down to the house, setting up a transfer relay. Solid plastic pipe sucks for longevity and it's a fruit tree orchard between the house and gen shed. The "maceta" for each tree was blasted using dynamite long before I got there. A 3-pound drilling hammer and drill and one massive WHACK and the rock gives way 1/4". Getting dynamite now is insanely complex and expensive. A marine has to guard it 24/7 until it is detonated. Procrastination was easy. The freezers are located halfway between the house and the genset and I used 10/2 direct burial cable which was not buried. Enough power for the kitchen and refrigerator freezers but not enough for the "house". Ariel? Yep as long as the power is not 127 or 254 volt alternating current. CFE would throw a fit. My very flaky power arrives via a 122' jump to my pole, then an 80' or so 2nd jump to the Siemen's breaker box in the kitchen. I am using a SJOO 10/3 commercial cord laying on the top of the ground between the kitchen and the house. It is starting to deteriorate. Gotta do something pretty quick.
