Advantages: Can't think of any - buy a third party battery at a tenth of the price!
Disadvantages: Disgustingly overpriced

...Original Equipment Manufacturer's (OEM) accessories are usually sold at a premium, but the price of this particular battery is verging on the excessive! Battery technology has improved almost beyond recognition, largely as a result of the mobile telephone industry demanding greater capacity cells in a smaller format - the knock on effect is that smaller volume products have been able to cash in on the research. Olympus have adopted the BLM-1 package as it's format of choice for it's latest range of mid to high priced cameras. With a nominal capacity of 1,500 mAh, using rechargeable lithium ion technology, this cell packs a considerable punch in a moderately small unit. Lithium Ion has distinct advantages over 'traditional' Nickel cadmium cells, being free of the dreaded 'memory effect' - where to maintain optimum capacity... Read review

Advantages: Long life, fast recharge, small size.
Disadvantages: None.

...from the small size of the battery (about the size of a box of matches, I'd say) and handy contacts cover. I can't vouch for usage in other equipment but in the EOS, this battery is exceptional and one less burden to allow you to keep taking those perfect shots, time and time again.

Advantages: long lasting
Disadvantages: might have problems when recharging it

...This lithium ion battery offers a long lasting video recording time for your cam recorder . It has the looks , the shape and the price as all other batteries and it is easy to use , just put it in the place for battery like the sketch shows on the camcorder . It is better and more of a high quality then the one that comes with the camera . Also by recycling it you can save the surronding enviroment . I reccomend also buying a new charger for the battery , because in my case the one that came with the cam recorder has let me down after two weeks from when i bought the camera. it just didn't want to charge the battery. what else should is say... it is just a normal battery...

Advantages: Long lasting charge, durable and easy to use
Disadvantages: None at all

...If you have a digital camera you might find this battery information helpful. I purchased a Canon Ixus 330 about a year and a half ago and as part of the package, you are supplied with one re-chargeable battery, a Canon NB-1LH. It is a Lithium Ion Battery, which are ideal for mobile devices, much lighter than earlier made batteries, more environmentally friendly for disposal and they do not forget they are charged...(yes I didnt realise batteries were forgetful either!!!) A lot of the digital Canon range (including my camera) doesnt have a battery indicator so it is highly recommended that you carry a spare battery with you. Therefore before I went on my jolly holidays I popped into Jessops and bought a Jessops branded NB-1LH. This I think cost me £15, about £10 cheaper than the Canon battery. I then made it my rule...
