So, it is “OK” to use that auxiliary battery to jump start the other car?
Another forum seems to indicate it could damage the Hybrid:

but is not very clear.
If I would need to take the Hybrid in for “checking”, maybe my better/cheaper option
is to buy a new battery for the Honda – it has been doormant for two years, and so I guess
may not be good to go after charging anyhow.
