    Posted: 17 April 2019 at 17:29
Dear Folks

Well, I've been away a while but I still have the gear and recently have dusted it off to get back into it. Perhaps not as much as I used to be into it, but I have some more time on my hands now, which is nice. It is in my line of work.

So I've got a Sony A700 and a Sony A55. The latter uses NP 50FW (I think) batteries and I think I need more.

I've got about 4 so far but only one is genuine.

Last week they were all fully charged and yesterday evening slipped off to take some fots with other projects too and came away reasonably happy. Except the batteries were quite poor. As in, although they seemed to be fully charged the camera decided they were flat quite quickly, within a matter of hours and, well, not that many photographs.

So. Considering I only have one genuine battery and the rest are all relative imposters, my question to you experienced folk is.

Is it worth getting genuine Sony batteries at 44 UK Pounds each, or perhaps copies of that may even be half price..

I might get another charger as well and so could end up getting a duplicate to keep on top of rapid charging. If I were to go for non-Sony, which manufacturer/source do you recommend, please?

TIA ;)

The Sony genuine batteries outlast the imposters when you reach 6 months to a year. The genuine batteries seem to keep going. The fake ones die quickly. Thatís been what Iíve noticed anyway.

Another thing is possible.
Charger my be a problem.
Old one have sign on back side BC-VM10, new one is BC-VM10A.
Difference is that "non-A" version charges non-genuine batteries, "A" version only genuine. "A" version charges non-genuine on 30%.

I have both versions (from A900 is "non-a", from A77 is "A" version) and genuine and non-genuine batteries.

The charger models you mention are for NP-FM500H batteries, the original question was about NP-FW50 batteries and you cannot charge these with the same Sony battery chargers (there are some third party chargers you can adapt to charge multiple battery types). In my experience the genuine BC-VW1 charger does charge non-Sony NP-FW50 batteries quite fine, at least as well as the third party twin USB-charger for this battery type does. Although, those non-Sony NP-FW50 batteries I have already are old and don't hold much charge anymore.

Thank you for the replies. I shall probably end up purchasing another either one or two genuine batteries for the camera.

I noticed Bristol had a combination of charger and battery for £77 with just the battery for £44 so I might go for that, but I shall consider things carefully.

It's true. But checking a charger is recomended.

Duracell also makes a version of that battery which is slightly cheaper.

It's worth running the batteries flat and charging them several times. That can sometimes make old Lithium rechargeables recover. All rechargeables in my experience work better with regular use, and need some TLC after a long period of non-use. But if they've gone completely flat at any time (< 3V per cell), they're usually toast.

The Sony genuine batteries are the better way to go. Not all the fakes are created equally but by the time you've ordered and tried the various imposters and separated the wheat from the chaff you'll end up spending more than just buying the OEM. They run longer, hold a charge better and are longer lived.

The Sony NP-FW50 W-series batteries were crap from the get go, undersized and underpowered by design. The generics don't last worth a damn.

The A700 Sony NP-FM500H M-series batteries are excellent. All the Sony cameras I still have run on them.

The battery issue is why I've stayed away from the A7 and A6XXX series to date.

To be fair it's not just Sony and Non-OEM batteries. I've had the same experience with Olympus and the BLN-1, PS-BLM1 and BLM-5 batteries.

The clone batteries from Duracell are rather ok (charged with a dual charger made by Jupio). My chinese clones are all gone (RIP - 7/7 after 3 years).

The Duracells are +/- 5 years old (4 pieces) all are running fine.

The FW50 from Sony are better - but not twice as good as the duracell ones (5/5 ok)
FW50 = +/- 70Ä - Duracell = +/- 35Ä

I also have a usb-charged little bit bigger battery that attaches to my belt with velcro (with a dummy insert) from Jupio - that should = 2.5 FW50's. It's rather recent 1,5 years old. It keeps the charge rather well (i'm using it rarely - but it's always in my bag as an extra backup).

I'll probably will need it the next week in Italy.

I've had a think about this and mulled over all of the responses and I think I'll end up buying the genuine Sony batteries for the camera.

Alas it won't happen yet, but soon. Other things in life get in the way as well. But thanks for all of the responses and your thoughts.

Beware with the A55 and original Sony batteries.

This may sound strange, but there may be a reason not to buy the original Sony battery. I read several reports from people stating that the A55 would no longer power up using the original Sony battery, but worked perfectly with a 3rd party battery. When one removes the lens in this scenario, the shutter is closed. I experienced this personally with my own A55.

The theory behind this is that the shutter, due to wear, draws more current over time. The Sony battery at some point will engage a fail safe mechanism as it thinks the camera draws too much current due to some failure. The 3rd party batteries do not have this protection and happily deliver power.
