Practical A.E.G Upgrade 2006

Are NiCd batteries superior to NiMH batteries for driving upgraded

AEG?

Ni-Cds have good performance in high-discharge and low-temperature

applications, but are subject to the problem of “memory effect” (the cell

remembers and maintains the characteristics of the previous cycle). They will

also self-discharge at a rate of about 1% a day. Sanyo and Panasonic offer good

quality NiCds.

NiMHs closely resemble the NiCds in construction but can offer 30% more

capacity and about 25% more power than the NiCd counterparts. The problem is

that they have poorer service life, tend to self discharge faster, and in certain

cases are subject to “memory effect” (refer to the troubleshooting section for

further information). GP offers very good quality NiMH cells.
