What is the specification of the battery/batteries for the Librem 13 v1?
Mladen Pejaković supplied some answers.
How many batteries are inside the case?
Apparently just one?
Is there a standard part number?
Mladen wrote: “TU131-TS63-74”.
It is unclear whether this is a part number of some particular original manufacturer that is reused by other manufacturers.
Is there a manufacturer/supplier and part number?
Still waiting for information on original/recommended manufacturer/supplier.
What are the usable/recommended minimum/maximum limits on its dimensions/shape?
Apparently all the manufacturers/cloners copy the shape/dimensions/connectors/controls of the original TU131-TS63-74 ur-battery, which was in some Dell (XPS13 8808?) or Asus (UX32K?) or Haswell laptop. Some sellers claim the TU131-TS63-74 can be used in place of a TU131.
What kind(s) of electric connector or connectors must it have?
What control/monitoring interface(s) must it support and what standards are followed for this?
What kind(s) of mounting holes/brackets/etc must it have and where must they be?
What are the maximum/minimum required/safe/useful voltage/current/power (V, A, & W)?
The standard voltage is 7.4V. Still waiting for all other information.
Can someone from Purism please definitively confirm any of the details needed for ordering a replacement battery/batteries?
Thanks!
