    I want to get a spare battery for my Casio compact camera. Where can I
    get a half-decent NP-20 battery at a reasonable price?

    For example, does an Inov8 replacement battery for £8.99 inc
    delivery. 7dayshop sells a replacement battery for £4.49 delivered.

    Are these good value or are they just cheap batteries that have much less
    capacity than the original? NP-20: NP-20:

  2. Although I aven't bought an NP-20 (I did have a dud by Hahnel from
    elsewhere) from them, other batteries I've bought from 7dayshop are
    lasting as well as the OEMs.

    Fercryinoutloud, for a fiver, it's practically disposable.

    We use a cheap replacement in our Canon Ixus and can't tell any
    difference from the original.

    Likewise, I usually use 7dayshop, and have cheapies for both my Mju500
    and E520, and I can't tell which battery I used each time, they all work
    as well as each other.

    I order lots of bit's and bobs from 7day shop inc batteries, memory,
    replacement caps and small cases. Delivery to the UK is normally less
    than 5 working days and their own brand stuff is good quality.

    Even feedback isn't reliable - most people leave it after briefly
    checking the item, it's only after use people realise the battery isn't
    as good as it should be.

    that said I bought a battery from Hong Kong - not advertised as genuine,
    it's not as good as the Sony original but after nearly a year of use I'd
    rate it as 80-90% of the original Sony in terms of capacity. It even
    holds the charged unused unlike a lot of cheap alternatives

    Not bad for £10 vs almost £40 for the sony.

    Too damn true.
    I bought a 32Gb USB stick on eBay recently which turned out to be a fake,
    even though it was UK despatched from someone with high feedback. In his
    defence, I got my money back.

    As for batteries, I've had good service from;

  9. The capacity of a battery is a key part of its specification and is
    explicitely listed (e.g. mAh: 630mAh). Therefore the capacity of
    different batteries is trivial to compare unless we are talking about
    fraudulent statements.

    The cheap knockoffs on ebay rarely live upto the billed capacity.

  11. Dealextreme isn't Ebay...

    And about fakes: A battery meant to look like a original Casio battery is a
    fake. How can a battery that clearly says it's not an original be a fake?

  12. That's also true of many of the expensive originals!

    I bought cheap ebay batteries for my phone. They were a third of the
    price, and accurately advertised as having 50% more capacity. I also
    got another set, much bigger, which came with an enlarged backplate to
    accommodate the size. They corresponded to nothing the maker sold, and
    gave me 4 times the capacity. They lasted a delightful month on a
    single charge! No need to take a charger on holiday!

    Incidentally the cheap Ebay knockoffs for my last camera advertised
    themselves as having 10% more capacity, and they certainly lasted at
    least as long as the maker's original.

    Like I said; rarely! With no way of accurately measuring the capacity I
    assume the original (sony or whatever) battery capacity is correct.

    I've bought batteries for PDA, several different types of phone and
    cameras from eBay. All advertised the same or higher capacity, only a
    couple actually lived up to that promise based on day to day use. TBH I
    expect that and provided the performance is not abysmal I accept it as a
    cost saving measure.

    I have been pleasantly surprised with the NP-FM500H I got off eBay which
    seems to hold pretty close to the original. I tend to swap them over as
    I charge and even after a month in my bag it still delivers similar
    performance to the Sony original.

    You have to watch out for old stock, especially for batteries that
    aren't all that popular. Last week I received a "genuine" Motorola
    battery for my phone, that was manufactured in 2006. A three year old
    Li-Ion battery is about at end of life. An after-market battery for an
    older device may actually be better.

    The problem with after-market camera batteries is rarely an issue with
    the actual cells inside the pack. It's more of an issue with tolerances
    of the pack (I've seen after-market batteries that were a tad larger and
    would not fit into the camera) or whether or not they properly
    implemented protective circuitry.

    I'd stay away from eBay, and in the U.S. buy from
