NiMH Charging techniques, memory

[Corndogg]

My Dive Rite mini wreck HID is down to about a 1 hour burn time these days so I charge it after every dive.  I have always been lead to believe that NiMH batteries had no memory and you could treat them however I wanted until I came across this:

Battery Life
Nickel Metal Hydride (NiMH) batteries are rechargeable and can be recharged for hundreds of cycles. Your battery life will depend on how you properly care for your battery. Gerbing's does not offer any warranty on the lifespan of your NiMH battery.

To break in a new battery properly, we recommend charging and discharging the battery fully 4 to 6 times to enable the battery to reach its full rated capacity.

NiMH batteries have no memory effect, but the memory is held in the charger. Over a series of charges, the charger remembers the charge capacity required to bring the battery to a full charge. If you run your battery for only 1 hour, then recharge, the memory will adjust to provide 1 hour of charge to recharge. This is not enough! To prevent this, condition your battery and charger by charging the battery for 10 hours and then draining the battery until your heated product no longer is providing heat. Be sure to always disconnect the battery from your product when it stops providing heat.

To increase the longevity of your batteries, don't leave them dormant for extended periods of time. We recommend that you completely charge and discharge at least every 2 to 3 weeks. Batteries left idle for extended periods of time self-discharge at a rate of 2% per day. Just remember to charge your batteries again before use.

I clipped this off of this site while researching my heater setup: 

I'm going to run the battery through several complete cycles and then do a burn test and then post the results.
