LiPo batteries

MouldyOldDough

My new laptop has a non-user-replaceable LiPo battery - that I was concerned about

But - it has so far - exceeded my expectations

Fully charged - the first couple of weeks - running time was less than 3 hours - this has now increased to more than 6 hours - its been running all day, since 9 am and its still showing 73% left (3 hrs 42miins)

Is this normal ?

ie) Do LiPo batteries take a few cycles to reach their full potential ? (pardon the pun)

I usually find that when the batteries were shipped with zero charge.  Items from the £ shops with those batteries are often flat
or below the nominal voltage where multiple charge/discharge cycles improve their capacity.

I would not buy a laptop with a battery that can't be changed by the customer.  It is just a grab your ankles activity by certain suppliers. 

Most laptop batteries use a number of 18650 cells which are lithium ION, they do not have memory effect and last 3 to 5 years.  When they fail I replace them and break the old one to check the cells that are still good.  I have a couple of devices that tell me the state of the cells.  I have made portable charger units out of good ones using kit off eBay.

LiPo batteries are not the same 
They are unique to a particular brand of laptop
