Switchgear DC backup load testing
Switchgear DC backup load testing
(OP)
Does anybody have a slick inexpensive way to load test a 120v battery bank? 10 12v lead acid batteries with a constant trickle applied. Please don't suggest light bulbs. I need something that a maintenance guy can use. Also, can you give me any reason not to replace the lead acid with gel cells.

Gell-cells are not an option in my book. Too many users think of them as "maintenance free" and this leads to some really bad incidents when they fail to perform. With the traditional flooded cells, you can see electrolyte levels and other visual indications.
If you go with the gells,, then I'd recommend a load test annually. Also, the gell-cells do not do well in hot environments, so think of your battery location.

Also Miller (the welding company) makes a nice/cheap load bank

The 110V 500W halogen floodlamps used in industrial and construction are a useful solution when you need something quickly unless you're talking about a big battery like a turbine critical services battery. For a substation tripping & control battery they work fine. They just don't look great!
