I am totally amazed to find the H520E battery IS a Li-ion. Although I have seen it mentioned I have presumed it was a typo until I found a picture on a website from the manufacturer. This is a significant change and it makes battery maintenance totally different.
It also means the H3 and H520E batteries are different. And the charger will be different.
