Sub DC Adaptors

Have "Energizer" aa/aaa battery charger uses dc/cc 12v-500ma adaptor. Can I substitute dc/cc 12v-700ma adaptor?

Without knowing what form of current limiting is employed by the charger the only safe recommendation is: no, don't do it.
Recommendation: in cases like this contact the maker and get advise from an engineer or technician that is familiar with the product.

Thanks for the quick advice Tim....one more q.....back panel of adaptor shows "output" as follows: aa-dc/cc 2.8/5.6v 700ma aaa-dc/cc 2.8/5.6v 350ma
Does this refer to ma current limiting or still need to talk with the mfgs?
Really appreciate your help, Tim

Chargers are designed for particular cells/batteries. If the charger you have wasn't designed for the batteries that you have, there is a danger that the batteries or the charger could be damaged. It may be OK to use the charger for a different battery than that originally designed for, but, in case of doubt, it is better to confirm that all will be OK with the manufacturer (of either the batteries or the charger, or both).
The charger, from your description, can take either one or two pairs of AA or AAA batteries. However, the charging currents that you mention are far higher than the "trickle current" amounts that, near enough, will always be safe for any rechargeable AA/AAA cell. Thus the charger must have electronics to sense when the battery is fully charged and reduce the current. Different battery types require different electronics. So, if your batteries are the wrong type, charging at full current could continue even after the batteries were fully charged..risking damage.
Hence, yes, if you are in any doubt, ask the manufacturer.

mfgs?
I would assume that 'CC' stands for charging current. probably max current with the maximum number of cells under charge.
A web search show many many types of 'energiser' charges. The one thing they have in common is a lack of data that would enable one to answer the question: "is it OK to use a larger transformer"
From the above data I would assume that fully loaded with AA cells it charges at 5.6 X .7 (max) for about 3.92 watts
You might want to read this http://www.greenbatteries.com/bachfa.html It seems to cover the highlights of battery charges.
