Batteries uninstalled...can I connect shore power safely?

I own a 2015 27 FB International Signature. I noticed my batteries would barely hold a charge, I found out they are "unstable" according to a load test. So I removed them and are waiting for replacements.
My question is, can I connect the shore power without batteries being installed? I don't want to damage anything.
Thank you in advance......

Yes, the converter can be used without batteries connected. This is essentially what happens when the Use/Store switch is in the store position.

Just tape off the battery leads so they don't short out.

A related question about battery connecting

As a newbe, I was surprised recently when on shore power, the power died (in a windstorm) lasting for two hours but I could not get the battery to kick in. I have a FC25, 2016. On the inverter remote control switch (green light) when I pushed the on/off switch the light went on and off. On the battery disconnect switch pushing the use/store switch changed nothing (the red light stayed on). So when I do not have shore power or shore power is not working, how do I get the battery to come on? Thanks for insight.

The USE/STORE switch will always be lighted when connected to shorepower. If not on shorepower it will be lighted only when in USE, which connects the batteries to the DC loads. I am not sure what you mean by getting the battery to come on. If you lost shorepower and also all DC there are only two possibilities: your switch was in the STORE position or the batteries are discharged. There have been a few reports of the relay not operating the switch but that seems somewhat rare. If your batteries are shot, you would not know when connected to shorepower as the converter supplies the DC.

NO!
Batteries, even 'pooched' batteries, act as an accumulator, (snubber) which protects against voltage spikes, and heavy amperage flow.

Without them, your eguipment can be Slugged with damaging loads.

You have a modern converter therefore there is no risk of a surge.
You can safely use the 12 volt system without a battery.
Per my previous post just protect the battery cables from shorting out.
