So far no.
All my NiMH do not exhibit memory effect. But it varies frm brand to brand. Some of the more ulu-ulu brand are prolly made frm lesser quality materials and will wear out faster den usual. Tho$e made frm better quality, will prolly la$t longer (and of co$...).

Yes and No. They exhibit memory effect but not to the degree of NiCd such as to be a serious concern. In any case, their limited cycle life of 500 compared to NiCd's 1000+ means that delibrately discharging them to reduce memory effect is a waste of its cycle life. NiMh will also suffer damage from being overly discharged.(<1V)

I always use the battery until it has been drained and then recharge them, just a buy a spare set.

Any idea if the MH-C401FS discharge the batteries prior to charging them?
