There's a lot of conjecture pertaining to this very subject.
The memory effect is the battery only using those cells that are fully discharged and charged on a regular basis. If there's only a partial charge then the battery will only remember those cells.
Lithium-ion: In the first instance may suffer from the memory effect. Fully charge the battery and allow it to fully discharge. The device using the battery will shut down when that point is reached in order to protect the battery.
NiMH: also susceptible to the memory effect. Same thing fully recharge and fully discharge.
NiCd: the oldest of all the rechargeable technologies are extremely susceptible to the memory effect.
The only batteries I can think of that dont let you fully discharge them are the lead acid type, lot older technology from the 70s. Big and bulky, these batteries are mainly used in security and fire alarm systems, they are permanently connected to a power supply.
