Hi! I'm looking to get a back up battery or two for my A900 and was wondering if the generic knockoffs on ebay are worth buying? Thanks for your input:)

Not sure I'd bother. Bought a generic (not from ebay), it worked well for a while then started behaving very strangely in my camera. I do however, have a Duracell equivalent which is serving me well.

The reputable makes (eg Ansmann) are okay - the key is to get a real one and not a fake.
A900, A58, 5d, Dynax 4, 5, 60, 500si/600si/700si/800si, various Sony & Minolta lenses, several Tamrons, lots of MF primes and *far* too many old film cameras . . .

What about a Sony refurb? They're about half the price of a brand new one. I just can't see spending $50 for a battery I'm only going to use for backup...

...actually I should clarify that last comment, the listing said "used", not refurb.

I recently purchased a pair of "Green Extreme" FM500 replacement batteries from Adorama. I haven't had them long enough to run them through more than one recharge, but they fit well in camera and charger, give a similar performance to Sony originals and are $19.96 with free shipping. When it comes to generic batteries, it's more important to be able to trust the dealer, and I've found Adorama to be a very trustworthy dealer.

These same batteries are available on Amazon, but they still are shipped from Adorama.

Thanks! That's good to know. I wish I read this sooner, I just went with the used on on ebay for $25 because the seller had good ratings. Oh well. If I ever need another battery I will go with this, that's not a bad deal at all!

I've purchased used batteries (from a dyxum member) for my Sony cameras and used Canon batteries from KEH and they were all in good shape - meaning they still held a charge well. If I were you, I'd use the one you bought for a couple of continuous cycles right away to see how well it holds a charge. You don't want to find out when you need it that it's down to 20%.

Well, if you're into buying extra batteries for the A900, think too of the vertical grip. It will take your old and your new battery, and actually improves the camera's handling to my mind. I use any batteries I can afford.

IMHO that's not the best way to use them, because batteries left unused tend to deteriorate and batteries which are used also deteriorate. I think you should swap batteries every time you charge them, so you have one fully charged one in your bag (once it's been recharged) but each gets the same amount of use and gets charged and discharged regularly. This also has the advantage of allowing you to see if one of them loses capacity.

Agree, its a good idea to rotate batteries.

I also don't think a battery being a "backup" is a reason to buy a potentially unreliable or poor lasting one! In fact, when you need your backup, surely that's the time you need the reliability?

I have 2 non original batteries - a Hahnel, which is very good, and a Duracell, which is clearly inferior. I had non original batteries for previous Sony and Fuji cameras which were also clearly inferior, in some cases badly so, didn't hold as much charge, didnt work properly with the battery meter, and would suddenly fail when they were low on charge.

There is a loss in LiIon bateries over time (about 12 years ago when I first researched them it was supposed to be in the order of 5% loss of capacity per year, but may have improved since then).

There is more danger in buying a Sony branded battery from someone that is not an official retailer - someone counterfieting a battery will put lots of effort into making it look right, but will have no interest in making it safe or reliable as they have no reputation to lose.

I've used some generic clones from places like 7 day shop and have found them to be generally reliable. If you buy a branded clone (Duracell etc) you shoudl get a good product, but again I'd say to only buy from somewhere you trust as someone might be trying to pass off a sub-standard battery as a real Duracell.

Yeah, the only back up batteries are in emergency power supplies. Batteries are an integral part of the kit, the lifeblood of the camera body so I don't mess around with aftermarket and only buy new Sony's. Regular usage and full discharge/recharge will greatly extend the life of the battery so it must be rotated. I used to mark my batteries with silver paint dots to keep track of them and use them in rotation (and a good way to track age/seniority so to speak) but that plan doesn't work well when using two bodies that share batteries. Now I wish I had used a date instead of a paint mark on the batteries, should have been thinking as that's what I do when I install new batteries in customer cars is write the month/year on the label with magic marker, if you see a car battery 6 years or older you know it's about done.

Just retired a Hahnel clone. They are supposed to be a decent brand. Bought in a regular camerashop...
