Customer Reviews

Essential; Optimal Sony Camcorder Battery
An additional large capacity battery is an essential purchase to replace the inadequate batteries supplied with most mini-DV camcorders. This battery is the best of the bunch, providing great battery life without being too bulky or pricey. Sony's other batteries are either too large (e.g. the QM91D) or don't last long enough to be worth the additional expense (e.g. the FM30 or FM50).

Moreover, if you are willing to pay an additional $150 for the Sony AC-SQ950 Quick Charger, this battery can be charged in under an hour! Highly recommended.

Notes: (1) Don't confuse this with the older QM71. The "D" is important (no on-battery power indication or Quick Charge without it). (2) Be sure your device takes an "M Series" battery. Sony has several lettered infoLithium battery "series" (e.g., the super small "C Series" for compact digital cameras) that all tend to look alike in unscaled online product photos, but batteries from different series are NOT interchangeable.

Should have been standard
I purchased this as an accessorry for my Sony DCR-TRV38 camcorder. It's got a long life and a neat battery check function on it. However, it is on the bulky side and extends the overall length of the camcorder when attached. One nice thing is that the viewfinder on the camcorder extends to accommodate the longer length. Sony really should have made this standard, as the included battery is woefully inadequate. It may be of interest to note that I needed to purchase a separate charger ($100) to take advantage of the quick charge function.

Excellent extended power for your camcorder
Highly recommend this battery. It is a excellent addition to the standard battery that Sony provides with their camcorder. I find I get more than 250 minutes battery life every charge. This is including using a light and flash that draw from the same battery. When the battery is not attached to my camcorder you can touch a button and a power level display shows you the amount of juice in the battery. Very handy when its in the bag and I'm trying to figure out which battery to use. It is a bit larger than the standard battery, but doesn't create to much weight or bulk.
Highly recommend this battery.
