I bought 4 wasabi power extended batteries for my XH-A1s and none of the will last longer than 2 hours of use after charging. I used the stock charger that came with the cam and charged them til the light on the charger did not flash. Do I need to charge them longer or use another charger or what?

Doug, does your original A1S battery run ok? The big Canon battery can run all day.

Usually new video cam batteries do take some time to settle in, they don't achieve full charge until they've been though
at least half a dozen full charges and full discharges.

Wasabi batts are numereous, hard to believe 4 are faulty. Suggest you number them 1-4 and keep rotating them.
And try this, when you see the battery full light on, take it off the charger and put it back again, see if it takes more charge. HTH.

Cheers.

Agree that you would do well to number the batteries, and keep track of their performance. My impression is that the Wasabi batteries are low cost and performance varies. A have a couple, and am not overly impressed.

thanks much, I will try your suggestions! Wish me luck!

I had 4 Wasabi batteries, 2 for the GH2 and 2 for an Olympus Pen.

One for the Oly died completely when put in the camera after the 4th charge cycle, never to take a charge again. The other for the Oly swelled up in the camera. Took 2 hours to carefully priy it out, had it swelled any more the camera would have had to go to Olympus for repair with warranty voided because of aftermarket battery use.

The 2 for the Panasonic GH2 never caused any major problems but also never gave any more than 50% of the run time the Lumix batteries did. So I gave them to a student who could not afford to purchase extra batteries for his GH2.

I guess I'll continue paying the price for OEM batteries, bite my lip and move on.

On the other hand I've had satisfactory results with Lenmar branded batteries in my XL, XH, and GL series camcorders.
