HP 3C 46WHr 4080mAh Battery

Large capacity
3400 mAh - this is 20% more than other batteries with non-branded cells of low quality

High durability
the cells can withstand up to 1000 charge cycles, which gives 2-3 years of trouble-free operation. Their capacity decreases very slowly and after 300 charging cycles (about 1 year of operation) they still retain more than 80% of their capacity.

Modern control electronics
It allows the battery to communicate with the laptop, providing information about the state of charge, remaining working time, or time remaining to be fully charge. The majority of models use electronic circuits from Texas Instruments, which are also used in original batteries.
