Product Description

Our range of digital batteries are designed to provide a high power output at a fraction of the cost of original manufacturers and can be used in many makes and models of digital device.

Rechargeable digital batteries are rated in "mAh" which stands for "milli-ampere hours". This rating is used to state the storage capability of a battery, e.g. a 1000mAh battery would be capable of delivering 1000mA of current consistently for one hour whereas a 2000mAh battery would deliver the same 1000mA of current for two hours.

Li-on rechargeable digital batteries can deliver 40% more capacity than comparably sized NiCd batteries and weigh less than the nickel-based batteries and develop no memory effect.

U-Bop battery cells are environmentally friendly, feature a very high energy density and have no memory effect. All batteries are produced to the highest quality standards. A built-in microprocessor safeguards the cells by limiting maximum voltage and by protecting against deep discharge, short circuit and overload.

Providing the correct power for your device, the PowerSURE Performance Battery is a rechargeable battery that gives long term use with repeated charges. To recharge the PowerSURE Performance Battery use the charger supplied with the device.

4.0 out of 5 stars Great and cheap 7 Jun 2010
Verified Purchase
I bought this battery for my Nokia 5800 with mixed expectations. On the one hand I was thrilled to have found such a cheap battery that seemed okay, but on the other hand there was this voice in the back of my head that warned me that nothing this cheap would be any good.

But now I've been using the battery for about three weeks and I'm really impressed. It lasts just as long as my original Nokia battery did when it was new, and I've had no problems with the battery what so ever.

5.0 out of 5 stars A good replacement battery 11 May 2011

This battery is fine and works. I received it promptly and it came fully charged. I've had it for a few days and with normal useage it lasts longer than my old battery. It still has a few bars left whereas my battery would have been in the red. For the price I don't think you can go wrong.

4.0 out of 5 stars Good replacement battery 25 April 2011
Verified Purchase
I needed a quick replacement for my phone battery, which I somehow managed to lose! and this seemed to be a good value replacement. I use a lot of power from my phone, tethering my laptop to it via bluetooth to get on the internet, and constantly using it for various applications throughout the day. I had been using a 2800mah battery which lasted for a very long time, but was very bulky, so when I was looking for a replacement I opted for this instead. As expected it can't compete with that battery for capacity, but it generally lasts the whole day for me, and since I charge my phone every night, this works perfect for me. It's a solid replacement battery at a good price, and holds out even against my demanding power needs, so I recommend it.

4.0 out of 5 stars Nokia phone battery 17 Aug 2010
Verified Purchase
This battery is a direct replacement for a Nokia 5800 XpressMusic phone. It supposes to have 1620mAh as oppose the original 1320mAh. There is nothing on the battery to indicate this, however it seems to work well and hold its charge better then the original battery (which may be aging). Need to test it for a longer period to judge whether it is actually better than the original battery.

2.0 out of 5 stars powersure battery bl-5j 18 Nov 2013

Unfortunately this to me was another bad battery buy. I immediately charged it upon receipt and inserted it into my phone. But alas it lasted no longer than the battery I wanted it to replace. Not a good buy

But then, after a year of swapping out every 2 days with my main original battery on my Nokia N900 (which it seemed to perform just as good as), the structure is failing - the contacts are no longer reliable so mostly it doesn't charge/work in the phone, and the top contact strip is wobbly; as are strips along the sides. That rather worries me as I don't want anything getting shorted or leaking (not seen anything to worry, but in this condition I don't want to use it anymore).

Though do bare in mind its been sat mostly in my backside pocket and sat on and moved around on top of all day at work. The original Nokia battery is better built and lasting just fine (a couple of years older too) albeit with the hologram almost worn off and faded writing.

After nearly 3 years, the original battery needed charging daily, but with the replacement in, the phone will go a few days before the battery needs charging.
