Remembering which of my devices are old method charging and which are new method is a pain.

I have several camping lamps from like 20 years ago that I almost threw out because they weren’t holding charge anymore, before I remembered to be fully draining the batteries and recharging them once a month. They work like new now practically.

I think it’s because of how the letter is written in cursive that we call it ‘double u’.

Happy birthday!
