6 hour rechargeable battery for Panasonic PVDV series camcorders.
Nobody wants the miserable experience of missing precious, priceless, once-in-a-lifetime family events because their camcorder or digital camera battery went dead, with no fully charged spare available.
For those who know better, just one spare is not enough protection.
The average user should endeavor to maintain at least two fully charged spares when going on any outing with their camera.
All sorts of actions and conditions can cause batteries to drain quicker than expected, from climate to various high-energy functions being utilized.
