It's probably the units that are charging at much higher rate that may be a concern.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

My owners manual (2000 C2 Cab) says to disconnect the battery when using a charger or the alternator could be damaged. Is this for real? I would have to reset my clock, radio presets, radio theft code, etc. - a real pain. How about for a low amperage charger, say 2 to 5 amps? Can I use a battery maintainer/tender without disconnecting the battery? I'm going into my 1st New England winter with this car and its already cranking slowly.

POST 2Original post

Really? I used a battery tender on my 2003 and now use one on my 2004. I have never disconnected the battery while charging or using the maintainer either. Maybe it is in reference to a high amp charger?

POST 3Original post

I would think a trickle charger/maintainer would be fine. It's probably the units that are charging at much higher rate that may be a concern. If your voltmeter is still running between 13 and 14 then you're alright.

POST 4Original post

That is referring to when higher amperage commercial chargers are in use (a good shop charger can put out between 30 and 200 amps, which can fry the voltage regulator or diodes in the alternator). Good quality battery maintainers are under 5 amps, and usually are only running at a fraction of one amp. We store cars over the winter for some customers using very good maintainers, and never disconnect the batteries.

This is a source reference. Confirm exact model applicability in the original material.
