We suggest a 6-8 hour charge of the battery for an average six months of use.

What does 2600 Mah mean?

The rating 2600mAh (or 2.6Ah) means the battery will produce 2600mA for one hour, or 1000mA for 2.6 hours of indeed 1mA for 2600 hours. The rating is the current multiplied by the time the battery can produce that current.
