I think the battery tender would be a good idea. That way the security system stays intact and the low current drain from the ECU and other components that draw energy when the key is off will not drain the battery. Everytime you disconnect the battery, you will loose the EPROM memory used by the ECU for data storage of load tables and A/F corrections. So every time you reconnect it, the ECU will have to relearn everything which will cause the A/F to run rich and then lean out a few miles. The ECU will do this a couple of times so it can reload the load tables. Using a battery tender will prevent the loss of data.
