No memory to worry about. Just be careful removing the positive cable that it does not come in contact with any metal. If it is the original battery, I would consider replacing it with a new battery. At the time, I found a great price on this battery
Amazon Amazon
Any 14-BS type battery would work.

WIS says remove main battery first, but if you wait 15 mins before touching aux battery (car goes to sleep) there should be no issues...

Pretty much what I did just wait no need to remove the main battery, just changed my SBC battery. Batteries are one of the very few things I don't order online even though it is cheaper. For warranty reasons, if mine goes bad I want to go to the store I bought it at and exchange it hassle free.
Also I swapped over to the 14 type/group battery for the upgrade compared to puny stock one.
