In the strict sense of the terminology they are not the same as cognaccruiser explains. Battery tender is a brand name that has evolved into a generic term, kind of like aspirin and xerox. A battery tender is a battery maintainer. A maintainer squirts a little bit of electricity into the battery as needed to keep it fully charged. A trickle charge continues to send a small current all the time.
To confuse the issue the terms are often used interchangeably so make sure you look closely at the description on the unit. A maintainer will usually use the word maintain. Many maintainers will work as a charger until the battery is fully charged and then change into maintenance mode.
You are wise to be asking before you accidentally ruin a good battery! :thumbup:
Battery Tender brand product is very popular, but there are others out there equally good. I have one from NAPA. Schumacher makes a good one.
My explanation was simply that a Tender or as other like to say "maintainer" is not the same as a trickle charger for the reason given. I was trying to not be too long winded. My bad.
I think we are all actually on the same page. See my post 20.
