After ~ 6 years of continuous operation, the battery of my Nokia 6233 a second career as a hot air balloon decided to start. Before the somewhat bloated companion would then explode ultimately, I decided me for a replacement battery to look. Now I was faced with the agony of choice and who knows the problem: lots of "original" battery pack for about 10EUR, almost always - gives you believe the reviews - promise more than they can deliver. Since I no 50EUR for a wanted to shell out real original battery (if it ever even gets this) and it apparently could not be on the safe side, even in this, I chose based on the reviews then for the above battery, in the expectation my phone will stay again for more than 1 day or 1Telefonat alive. So far, this also works very well. The first charge held with moderate use (SMS, short calls) ~ 5 days. Charging then took only 30min (age approximately 2 hours) and the battery is as yet no performance degradation. The longevity remains here But still the great unknown, but hope dies last known. In summary, for the time being highly recommended.
