I recently bought a replacement Panasonic cordless phone battery but didnt notice it was an NI-MH. The previous one was an NI-CD. When I put in the new one, there was a burnt smell to the contacts.

well, the voltage of the battery can hardly cause something to burn. I suspect it is the plastic you smell. Many smell burnt.
technically, there is a difference in charging the 2 types, practically there isn't.
the memory effect of nicd IS real. They have improved it but nimh is superior in that respect. that means you get long talk times per charge even on old batteries because they fully charge until they die of too many recharges and don't recharge at all.

If the voltage is right, the battery will be ok. The change to Ni-MH for replacement batteries is just to provide longer talk time and to eliminate the memory effect associated with Ni-CD batteries. The memory effect is sort of a long story, but it causes older Ni-CD batteries to not hold a charge as long as when new. I won't explain it here, because I don't know how true it is.

the different solutions are maximum stunning, the single element i've got not seen from them is that ni-cad batteries can develope a memory. they must be thoroughly depleted before being recharged or their means will drop notably. I used to recharge my old VCR ni-cads after each 10-15 minute use. After a on an identical time as, they found out to purely final quarter-hour. At $50 each I found out the puzzling way... greater modern-day batteries have not got a memory subject.
