Hi, my P755-S5285 Toshiba Satellite Li-Ion laptop battery pack PA3817U-1BRS seems to have died..10.8V 4200mAh. Inside it has 6 x SANYO K UR18650A R2112 cells... 1. Can these be safely replaced? 2. What are the best replacement Li-Ion batteries to use to replace the SANYOs? 3. Is it 3.6V or 3.7V...? 4. What mAh capacity would be best to use? 5. Can I increase the 4200mAh to what amount and how? 6. What do the ''K'' and ''R2112"' and 'P23B'' etched on the cells' plastic covers mean? 7. How can one identify and differentiate clearly between the various types of these Li-Ion batteries? Thanks to all your comments and advice.

A few years ago I bought a kit of weird small screwdriver heads from Amazon. I initially bought it because I needed a special tip for removing my Macbook Pro cover to replace the battery. But I've used it for a ton of other stuff since getting this kit.
Establishing the connection to the battery terminals should now enable charging. If the charge current stops after 30 seconds, an activation code may be required. Some battery manufacturers add an end-of-battery-life switch that turns the battery off when reaching a certain age or cycle count. They argue that customer satisfaction and safety can only be guaranteed by regularly replacing the battery. Mind you, such a policy also rotates inventory.

If you still only get a red flashing light and the battery won't charge, boost the battery some more. I find the battery charger will recognize that the battery is good again when you boost it to between 10 and 14 volts.
