That goes opposite to my understanding of NiCads or NiHM. You "wake them up" with a peak charger. Even better to cycle them if they have sat around a while. Nicads self-discharge at 15% and NiMH at 20 to 25%. Trickle chargers are good to keep a battery "topped off". Also called a "float charger" for that reason. You charge them rapidly (1/2 to 1C) and then maintain the level with a trickle (1/10 to 1/20C).

I have mine on trickle chargers on a timer for two hours a day to keep them ready for use when I get an opportunity. I plug a 12 outlet strip into a HD appliance timer set to switch off at the hour I leave work. Once a month I cycle them twice with a fancier charger/discharger.
