Memory Effect in NiMH Batteries?
The party line is that Nickel-Metal-Hydride batteries do not have any memory effect. Perhaps, perhaps not. See HiMH Batteries, Memory, and Thermal Runaway for one person’s test results and other information. Care and Feeding of NiCds Here are six guidelines to follow which will hopefully avoid voltage depression or the memory effect or whatever: (Portions of the following guidelines are from the NiCd FAQ written by: Ken A. Nishimura (KO6AF)) • DON’T deliberately discharge the batteries to avoid memory. You risk reverse charging one or more cell which is a sure way of killing them. • DO let the cells discharge to 1.0V/cell on occasion through normal use. • DON’T leave the cells on trickle charge for long times, unless voltage depression can be tolerated. • DO protect the cells from high temperature both in charging and storage. • DON’T overcharge the cells. Use a good charging technique. With most inexpensive equipment, the charging circuits are not intelligent and will not terminate pr
