In terms of using them there is no maximum. All a mAh or mWh rating refers to is the maximum current or wattage the batteries can supply over one hour. It is the device they are powering that determines the actual current or wattage consumed.

All a higher rating means is that the battery will last longer between charges. It is charging the battery that may present a problem. Depending on the charger it may not properly charge the batteries or take a long time doing it. Though that is easily solved by using a separate properly rated charger for the batteries.

You also need to be aware of the type of battery. A charger designed solely for NiCad batteries may fail to charge NiMH types.

They will probably work perfectly OK. The specs do say 750mAh or greater so there is a fighting chance the charger can handle 1000mAh batteries.

Mind you not much point buying them in packs of 12 when you only need 2 (unless you do have six phones of course). So buy only as many as you actually need.
