Can we put a verb right after the verb 'help'?

Hi,
You can use the bare infinitive in that case, but your sentence is not quite correct.
Try to say one of these instead:
He helped her change the battery.
He helped her to change the battery.

HongkieFor example, can we say "He helped change the battery for her."?

Yes, you can. Most speakers would accept your sentence as meaning that direct help was provided. Help is usually followed by an infinitive verb - here are two other examples, again meaning that direct help was provided:

I helped to clear

Thank you, Regards.
Thank you, Clive.

It seems to me that "They helped redecorate her flat." is wrong. There must be an object before "redecorate". Am I right?

No. The object doesn't have to be there. It can be worked out from context.

They helped (whoever was redecorating her flat) redecorate her flat.

Hi,

Help- is one of those catenative verbs that can be correctly used with or without the infinitive.

Thank you, CalifJim.

Clive's answer makes me think that we have to put the object "her" there while the word "to" is optional.

That is also what I have learnt from grammar books.

I would appreciate if Clive and Regards can comment on this.

Thant you.

Thanks Clive.

Is "help" the only verb that can be followed by a bare infinitive without an object without having an object there?

We were told that there must be an object between the main verb and the bare infinitive.
e.g. He makes her cry. We let him go.
