Think of the "tender" as a device to "tend" a fully charged battery- a balance against the draw of the alarm, radio etc. and also against time and temps.
a "charger" will charge a decharged battery.
for most motorcycle batteries 5 or 6 amps is about right- a higher charge rate can damage the battery through heat and/or boiling out the electrolyte
so a charger chargers, a tender tends.
when I get my new battery in a few weeks I'll charge it at 5 amps for about 12 hours before putting it in the bike.
once it is in regular use, I'll plug it into a tender.
should the battery discharge, I use a charger

find the amp hour spec ( say 32 ) divide by charge rate ( 2) = 16 for this example
I usually do this out of the bike- on the floor inside a metal baking pan- rare but I have seen new battery cases split or leak when first activated...ventilated area is important too....hydrogen gas
check with a meter that your charger puts out no more than 15 volts DC ( 14.8 is perfect), if it does, find another.
