BP-U65 vs Sony BP-GL95A battery

BP-U65 main with logoSony BP-GL95A

Michael Goldberg had a used Sony BP-GL95 battery ($599.00 … new) which he kindly tested against the BP-U65 battery and the 2 batteries tested out to be about the same length in use on an Ikan IB1000 LED light which draws 75 watts of power. That means the BP-U65 is conservative on watt hours or the electronics are better on the battery or the Sony BP-GL95 is old considering it is rated at 93 Watt Hours.
That is, by no means, a
definitive test as the BP-GL95 was powered down after 1 hour and 30 minutes when the battery light turned from Red to Orange. He powered the battery back up and found it still had power so this little test he did only indicates the BP-U65 is probably understated at 74.9 Watt Hours of use. The Ikan IB1000 LED should have killed the battery at 1 hour. The light is rated to draw 14.4 volts … same as the 2 batteries. Remember the BP-U65 will not be sold after the end of June on Amazon.jp.

Pic on the SWIT battery is from the S-8U62 which is the same information on the SWIT S-8U63 …

A little bit more information on the BP-U65
(SamSung cells) and a comparison with the SWIT S-8U63 Battery.
The SWIT S-8U63 (made in China) does not really provide much information on the bottom of their battery? I have always wondered about this but, no matter, the S-8U62 has proven to be a good battery … so … take what I say on SWIT batteries as my experience with the product!

Here are the stated differences none-the-less:
SWIT S-8U63 14.4 V, 4400aMh, 63Wh, decoded for Sony cameras. You can read-out the battery life and charge status on the on-camera monitor. Rated at 4.5 hours without the D-TAP/USB2 running. Rated for use with the Sony FS7.
Cost listed at B&H/Adorama, $192.29 usd = 23,000 jpy
Amazon USA, $199.00 usd

BP-U65 (made in China) with SamSung Cell structure 14.4 V, 5200aMh, 74.9 Wh decoded for Sony cameras. Read-out the battery life and charge status on the on-camera monitor tested, by me, on the Sony EX3 at 320 minutes or 5 1/2 hours without use of D-TAP/USB2. The Sony FS7 tested out at 328 minutes or about the same as the Sony EX3 … the EX3 is 10 years old at this point and I guess the electronic power draw is similar because of advances made in the last 10 years in electronics.
Cost listed at Amazon.jp, 26,000 jpy. So far this is the only site to sell this battery with SamSung cell structures as I personally negotiated with the manufacturer to have these cells in the battery. You can check out my experience with Chinese made cells on the first blog on this battery.

'Me thinks' … the BP-U65 clearly has the advantage in power and battery charge.
Send me an email if you find you need this type of battery and we can work out a deal.
