Batt® Battery Compatible with Nokia BL4U BL 4U BL-4U 3120 5530 8800 E66 E75 900mAh

Over the years I have dabbled in rechargeable batteries and one of the most accurate ways I have found in quickly confirming if the battery/cell is going to be good is to weigh them. As the Nokia 310 last for over 25 days with a full charged battery I have not waited the fully length of time for it to discharge to write my review. The battery arrived part charged (3 bars out of 4 on the display) which will probably mean it will take at least 20 days to discharge. I have been testing the battery for over 4 days now and it is still showing 3 out of 4 bars. Which is what it should be doing. My original Nokia battery weighs 21.18g This replacement battery weighs 22.78g The cheap, clone batteries generally claim very high storage capacity but when you weigh them they are a third of the weight. This is not the case here. Ok the Nokia (original) was rated at 1000mAh and this one is rated at 1000mAh (on the battery although it said 900mAh on the purchase page), but going by the weight factor I imagine that this replacement battery will easily run for 25 days or more. The build quality of the battery is very good, looking and feeling as it should and as it weighs a little more than the original I expect no problems with this.

Arrived as described, as pictured, safe and sound. This battery appears to work well and I had no issues using it with my 20+ year old Nokia which I recently came across during a clear out of tech, thinking I’d lost it. The battery appears to be decent enough when it comes to build quality and it fits just as good as the original Nokia branded battery. It works perfectly fine though I’m unable to test capacity due to the Nokia phone using a proprietary charger and not USB. Recommended.
