Review on ANVOW Rechargeable AAAA Batteries for Surface Pen – Powerful 1.2V 400mAh Ni-MH Batteries with Storage Box, 2 Count by Kate Gagnon

UPDATE: Yes, those batteries suck. They do not hold a charge and only charge up to 12% of their maximum charge. It charges from my charger in about an hour, which is great. My stylus is no longer empty and I can charge it! My problem is that my stylus says it's empty even though it hasn't been used for about a month. I can't expect it to charge forever, but my regular A-quad lasted about a year. It doesn't matter since I have two I can unplug the charger but that lowers the points. If you hate buying batteries, get these. If you can't bear to charge the batteries every 5-30 minutes or so, use regular batteries. It's a fair compromise, but I wish they wouldn't dry out because they weren't used.
