Comments about IDX IDX 7.4V, 5000mAh NP Style Lithium Ion Battery With "Secured Interface". For Panasonic AG-HM70 and AG-HMC150 Camcorders:

Recommended by the sales man, this battery fail to hold power overnight. the first month after new was ok. I am on month 6 after purchase. if you going to use the battery the same day will perform ok although not to the fully extend of its advertised time. if you fully charge for next day or days will drain fast when you will start to use it to the point will not reach the hour. the small cube batteries Panasonic brand and a general brand I got from the [...] still perform as expected. if you want a battery for 2 hrs or more performance buy a original not this one. yes it is more money but works.
