I think that something is wrong with this in your catalog: item is labelled "Visonic Replacement Battery For MCS-710" but at the attached image we can see "6H320BC 7.2V" marked on the side of the battery . The MCS 710 notice says that the needed battery is an ER34615M type (3.6V) .
It's the picture wrong or the battery is really destined to an MCS-700 (Ni-Metal, 7.2V battery needed) ?
Thanks.
