How-to: revive an APC-Smart UPS 1400

Some days ago a friend of mine gave me his old APC – Smart UPS 1400 because the batteries after 5 years on-line were gone and he preferred to buy a new (but cheaper) UPS instead of replacing them.

I immediatly opened it and found that it uses two sealed batteries with 7,5 amp-hour capacity and 12v nominal voltage connected in serie to obtain a final nominal voltage of 24v.
