OT, Dead APC backup

[Snow White]

Most times the units will function with a new battery installed, but 
you must open it to see what battery specifically it needs and most 
times batteries are need what a new unit costs.  When you want to open 
a UPS pay attention to the Htz.  50-60 Htz is the same frequency as the 
human heart.  So, with the right frequency you can jump-stop your 
heart.  Always use insulated pliers to uncouple the batteries to avoid 
a shock.  Thankfully this frequency is very rare in UPSes that are 
sold, therefore most are reasonably safe to work inside - just be 
careful.  By the way, they are very simple devices inside.

Most battery companies sell only minimum orders and a single UPS does 
not require enough batteries to surpass the minimum order - collect 
them up and fix all at once.

Don't forget to recycle the batteries - the dumps do not need the toxic 
chemicals from your batteries.  In Canada, Canadian Tire and some Fire 
Stations will take them at no charge.
