Disconnect terminals while charging with battery minder?

Do i need to physically disconnect the terminals from the chassis battery while it is hooked up to a "battery minder" charger?

There is a chassis battery disconnect button close by that I engage when in storage. But there is a sign next to the battery that states to disconnect terminal while charging to prevent damage to sensitive equipment.

Thank you for replies.

    No disconnect is required. If rating is less than one amp I recommend using the disconnect.

    Disconnect the terminals. It will be a reminder to clean them before reconnecting.

    Simple answer is that you do not need to disconnect to use the battery minder.

    Yes, a good idea to verify that battery terminal connections are clean and tight.

    There are a number of Battery Minder/Tender (Two different brands of same subject) The one I bought last Halloween can hit 70 amps in jump start mode, 20 amps in bulk mode or I think 3 or 4 in float mode.. I really needed that 20 amps.

    The answer is no, you don't need to disconnect (except in teh 70 amp mode) and most of 'em can't do 70 amps.

    I wanted a really good smart charger.> That's why I got the one I got. Store did not have anything else that looked as good. More expensive yes. as good no.
