Today I picked up the makings of my future battery bank. I got four CS3 HRL12390 batteries rated at about 108AH. These batteries retail for about $250 and I scored an excellent deal and paid a fraction of that. My initial calculations show that I should be able to get about 5 days out of these operating 24 hours a day. I know I won’t be operating anywhere near that so I’m willing to bet I could last about 2 weeks.
I’ll say one thing, too. These puppies are heavy! They weigh in at just under 73 lbs ea. Here’s the manufacturer’s description:
HRL 12390W is specially designed for high efficient discharge application. Its characteristics are high energy density, small footprint and high discharge efficiency. It can be used for more than 260 cycles at 100% discharge in cycle service, up to 10 years in standby service.
I probably won’t be able to get started on the bank project until after Thanksgiving but I’m at least happy to have the batteries sitting in the garage.
