My alternator broke down recently when riding, and the engine drained completely the energy of the battery. It was almost empty. I got the battery checked and they told me it was ok when recharged. Now I have it recharged, but should I replace it?. It is not brand new, maybe it's at the 60% of its usage.

Thanks.

I wouldn't worry about it until it starts causing trouble. It should have lots of life left.
 
No need mate. Automotive batteries are very resilient. Look for the 'first charged' date on a sticker, you should have at least 5 years out of it following that.

If you'd damaged the battery (sometimes faulty alternators overcharge) you'd know about it pretty quickly.
