Re: [AFMUG] Sealed or flooded batteries for DC backup?

[chuck]

I used to insist that once a quarter - if a tech was visiting a site - they 
took an extra half hour – pulled the power and logged cell voltages every 5 
minutes for at least 15 minutes in an onsite logbook.  Bad cell will show up 
pretty quick.  

Then send the results to the office where they can note in a master log book 
when the last battery test was done.  Ditto for reading the hour meter on the 
generator to make sure it was doing its exercise cycles properly.

Yea, but at the cost of those plus the size I can pay someone to drive once a 
year and do it. Although if I were to do it again I think I would just put in 
bigger conditioned cabinets so I could put whatever I wanted in there.

  AGM still needs an annual check if you want  your sites to stay up. We 
started a maintenance routine after we got caught with our pants down. We load 
tested them once every year and always ended up replacing 4 or 5 across all the 
sites. Maybe 50 or so sites or roughly 100 batteries. So maybe a failure rate 
of around 5%. Maybe I was just buying crappy AGM but they weren't cheap.

Gave up flooded years ago.  Had a few sites where the APC exploded the 
batteries.  Even when that didn't happen, I got tired of the yearly battery 
check and fill at all the sites.  When I started my own company I switched to 
AGM and never looked back.  They are amazing.  Also, we don't use APCs anymore 
except at a couple of large sites where we use the 3000XL, which has a much 
better charging system.

Re: [AFMUG] Sealed or flooded batteries for DC backup?

[Carl Peterson]

Best bang for the buck depends on a lot of things.  What does maintenance
cost you?  What does shipping cost?

I've settled on Northstar NSB100FT Red for our core sites.  If I get 8-10
years out of them without touching them, then I'd say they are a good
deal.  Less then 8 and they aren't worth it.  More then 10 would be best
bang for the buck IMHO.

[AFMUG] Sealed or flooded batteries for DC backup?

I have been really liking flooded batteries over the last 10 years or so
because I am able to service the battery and extend the life but I am
finding that on sites that I forget to add distilled water at least twice a
year sometimes the batteries dry out due to the charge controller over
gassing the batteries.

Right now I'm trying to decide between Walmart deep Cycles, rack mount
telecom batteries or just sealed RV Marine deep cycle batteries.

What is the best bang-for-the-buck currently considering the life span and
capacity ?

Thanks
