That test is not very relevant, unfortunately. You can easily get false 
results ( as in battery OK when it is not really OK ). The only relevant 
test is under real load, which is why I suggested using a small motor or 
a light bulb.

It's your choice but unless you short circuit the terminals which you 
should not do with ANY battery, there is no danger. It's as dangerous as 
working on the electrical system of a car or with a battery for a 
flashlight. True, it's 12V vs 1.5V but still not dangerous. All you have 
to do is to disconnect the battery ( which you know how to do, since you 
replaced it once ), connect a lamp with a 12V light bulb to the 
terminals and use a clock to monitor how fast does the battery discharge.

Unfortunately that list is rather unmaintained.
