Aftermarket BP-U battery % remaining

I have a Watson BP-U30. The first time I used it, it had --- instead of minutes remaining. The next few times, it displayed 120-130 minutes remaining. Now, a few more charges, and it is back to --- remaining. This is on a PXW-X180. Is this a faulty battery, or do aftermarket BP-U batteries simply not display time remaining?

Re: Aftermarket BP-U battery % remaining

It may just be that specific brand. Can you find a "SWIT S-8U63" to test on? This is the aftermarket battery most rental houses around here offer.

Re: Aftermarket BP-U battery % remaining

No Swit for me to test. I looked at their batteries, but their BP-U60 seems to be the size of a BP-U90, due to that power tap they put on it. I just went ahead and bought a used Swit dual charger for $90. Figured I will be fine hot swapping cheap batteries if the time remaining displays aren't reliable. My Sony BP-U30 says 30 minutes minimum at 2 LED's, and 15 minutes minimum at 1 LED.

The Watson showed 148 minutes when I turned it on earlier tonight, but now it is down a few bars and back to ---.

Re: Aftermarket BP-U battery % remaining

My experience with aftermarket batteries on Sony camera is that they are not always correct in the information they show, unlike all original Sony batteries which are accurate until the last minute of power they supply.

I also once had experienced a camera shut down mid recording saying the battery is not a original one. This is one of the reasons I never use a aftermarket battery in a camera where I have to be 100% sure how much longer I have left to record.

Re: Aftermarket BP-U battery % remaining

It seems Sony slightly changed how the battery data is read on newer cameras so third parties had to update their batteries. You need the SWIT S-8U63 with the blue strip, not the red one, for the PXW-FS7, the X160 and X180. All new SWIT batteries with the blue strip on the battery label should be compatible with the X180.

Re: Aftermarket BP-U battery % remaining

Sony going and messing something as simple as power up!

I just ordered a 95 watt DSTE BP-U tat is slightly shorter than a Sony BP-U60. I would rather have double the runtime for 1/4 the price than a battery gauge reminding me of how much I spent for so little amount of minutes. I will be hot swapping batteries on the charger after each news story, so I call these "burner bateries". At $60 (vs $240!) a piece, expendability is expected.

They are not messing it up, they just don't want you to use a after market battery.

Wow.

You would have/must have hated the days of BP-1 "chocolate bar" batteries than BRAND NEW ran a Betacam for MAYBE 45 minutes if you were lucky.

Re: Aftermarket BP-U battery % remaining

NP1, and on my first Betacam, I had that dual NP1 piggyback mounting system. :-)

Re: Aftermarket BP-U battery % remaining

Yup. NP1. 1A and !b were the 13.2 and 14.4V versions.

Not sure how I came up with BP-1.

D'oh!

We didn't have the dual mounts but we DID have the "black tie edition" nylon belt packs, which at 10 lbs or so gave me ALMOST 3 hours of shooting if fully charged for a Betacam BVW-507 w. PVV1 or 3 BetaSP back

Re: Aftermarket BP-U battery % remaining

Well, plunked down $60 for a DSTE 114 watt BP-U60 size battery. The time remaining feature actually functions full time, unlike the Watson which displays 120 minutes at first, then goes to --- after that. The DTSE starts with 345 minutes, but looses over DOUBLE the minutes the camera is actually powered up for, so I have to do divide by 2 conversion in my head. Still, a LOT of energy in a small package for a small amount of money, I like it. It also has a blue stripe on the back. :)

Re: Aftermarket BP-U battery % remaining

They last much longer than the similarly sized Sony OEM versions, and the "off" factor of time remaining is consistent, so you can do a quick mental math calculation for time remaining. I for instance know my camera will power off when the time remaining says 15 minutes! Unfortunately, one of the chips in my 2 DSTE batteries died, so the battery will charge and show voltage on the charger, but the LED fuel gauge will not work and it will not power up on the camera. DSTE said I could mail it back to Asia for a replacement.

For the $$ though, it is definitely worthwhile! I also started buying their NPF batteries as well.

Re: Aftermarket BP-U battery % remaining

Thanks for that info mate. Is it true that if for some reason the camera powers off while recording you will loose the footage if using the SxS to sdxc card adapter?
