Canon Battery Grip July 20, 2011, 12:25 PM
Exercise Your Battery - Do not withdraw your Battery Grip dormant for prolonged time.

Calibrate Your Canon Battery Grip in time (once a month).

Store your Nikon Battery Grip in a bathe, dry, cool location away from heat and steel objects.

Do not charged to higher voltages than its threshold voltage. Only do a fully discharge every 30 charges.

Do not short-circuit. A short-circuit may start severe impairment to the Pentax Battery Grip.

Avoid propping your laptop on a pillow, blanket, or other soft surface that can heat up.

Consider extracting the Sony Battery Grip from a laptop after running on set power.
