The boss in local battery centre says it's ok to connect neg charger

However, car's user manual suggests connecting to somewhere on the
chassis. This can be a pain, getting a good connection. Any thoughts TIA.



assuming it is a normal car then connecting direct to the battery will
be ok. the only good reason to make a remote connection is if you make
the remote connection last to connect and first to disconnect, this way
any possible spark as you connect/disconnect will be remote from the
battery which may have given off some flammable fumes.

Modern chargers do not usually make any sparks upon connection in any
case. It is still good practise to turn off the charger before
disconnecting.
