CTEK MXS 5.0 battery charger as maintainer

[Alec01]

Hello all,

I've just bought a CTEK  MXS 5.0 12V/5A battery charger, in order to charge my G30 90Ah battery. My battery is still ok and enough charged. But I've bought it in case I need it in the future.
Can I also use it as a battery maintainer while programming my NBT Evo ?
I know there are other maintener tools for that purpose, but I wonder if this CTEK can also do the job. It's for my personal use.
