What do standby and cyclic use ratings mean for the UB1250ZH battery?

[fulmenatrum]

I've been doing a project recently that requires a UB1250ZH Universal Battery rated 12V and 5Ah. Although I understand the concept of Ah, I'm having a difficult time in figuring out what the ratings for standby and cyclic use mean. For an example, it says -

Standby Use: 12.6-13.8V, the Initial Current is 0.75A
Cyclic Use: 14.5-14.9V, Initial Current: 1.5A

Does this have something to do with recharging?

Thank you! Any help would be much appreciated.
