A spare battery what an excellent idea!!!
My last 3 phones have all been Nokias and I have to say as muc as I have liked the phones and the features that they have the one thing that always annoys me about them is there batteries.
No matter how you treat them, whether you let them drain down to nothing and then charge them (As the manuals tell you to do) or to charge them up every night as most people do.
Nokia phone batteries never last and after about 6 months will generally only last a day on full charge so a spare battery especially one of this standard with the Advanced Lithium-Ion technology that lasts longer for the sane charge is a must buy for all Nokia phone owners!
Nokia Original Accessories give you the performance for which Nokia phones are famous. With Nokia Power Management accessories you can extend the use of your phone for longer trips away from home.
Advanced Lithium-Ion technology employed in this battery provides maximum talk and standby times in a lightweight package.
