I have 2 original Nokia BP-5L's, one in the device and the other on charge. On long trips when I need more than 2 I use the Sido's that came with the charger. They are fine, do the job and last almost as long as the Nokia's

I also have some fake Nokia lookalikes which seem ok too. I just don't like the subterfuge; at least Sido put their name on theirs.

Some of the HK dealers are excellent and replace goods if they are unsatisfactory. Others ignore correspondence and don't. But, overall, they provide us with an excellent facility and great value for money. I have a pile of batteries, chargers, cables, adapters, that I bought cheaply and which perform perfectly.

Just because the Nokia logo is on something doesn't mean it won't explode or break in the first month and yet costs 6 times that of the HK items. The Nokia wall charger that came with my N800 failed after 3 weeks - list price £25. I bought a HK item for £5 and that hasn't failed yet.

What's the moral? Just because it is expensive doesn't guarantee it to be good. Just because it is cheap doesn't necessarily mean it is rubbish.

TA-t3, Thanks for the informative post. The battery scenario is not all cut and dried.
