This is a high capacity 4.35 volt cell.











The cell look very good, the two cells tracks nicely and capacity does not change with load up to the rated current.















Test with 4.3 volt charging



Using a slightly lower charge voltage reduces the capacity with about 0.15Ah

















Test with 4.2 volt charging



Going down to a normal 4.2 volt charger cost 0.4Ah in capacity.

















Conclusion

These batteries can be interesting to drive led lights due to their slightly higher voltage, but it looks like LG has traded high current ability for capacity compared to the older 3000mAh cell.
When looking at Wh, this cell can match a 3400mAh cell, due to the higher voltage.

I will call it a very good battery, but a 4.35V charger is needed to really use it.
