Charging wireless keyboard

[MarkA2a]

I purchased an ex-display model of an HP ENVY All-in-One-27-b205na from Curry's about a week ago. There was no box or any documentation - indeed, all I had was computer itself, the power cable, mouse and keyboard. I have now discovered that the keyboard has rechargeable Lithium batteries (that cannot be replaced) that need to be charged periodically. No cable was supplied for me to do this, but I have one such cable anyway. My question is this: how long does it take the keyboard battery to recharge. There is no obvious LED to show this, I cannot find instructions online and the HP site does not tell me this information.

The specs of your machine is

   https://support.hp.com/au-en/document/c06067838

which shows

• Battery: Li-polymer 450mAH
• Battery life: 6 months (typical)

Normally you should get full charge in 3hours and twice a year. But you would need more charging cycles when it getting older.
