Simple swap with built-in safety circuits

Installation follows the normal Ultrabook battery removal procedure: power off, open the case, disconnect the old pack and connect the new one. No soldering or firmware steps are required. The most common issue is forgetting to seat the connector fully, which prevents charging. The protection circuits guard against typical handling mistakes.
