It slots into the battery bay using the original SBP-09 footprint and connector. If your MyPal shuts down mid-task or won't hold a charge, this is the direct swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eA686 \/ A696 \/ A626 platform fit:\u003c\/strong\u003e\n    All three MyPal models run the same 3.7V battery rail, share the SBP-09 form factor, and use the same connector pinout — one cell covers the whole family without any mechanical modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on MyPal hardware. The BMS accepted the charge handshake without error flags and held voltage within spec across the full discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eRAM data protection before swap:\u003c\/strong\u003e\n    Sync all open data to your host PC before pulling the battery. The MyPal stores active application state and unsaved files in volatile SRAM — that memory is powered entirely by the main cell. Full power removal clears it instantly.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the MyPal A686 loses contacts and calendar entries after a battery change\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe A686 uses SRAM for working memory — not flash. SRAM requires continuous power to retain data, and the main Li-ion cell is the only source. The moment that cell is removed, any data not yet synced to a host PC or storage card is gone. This catches users off guard because the behaviour looks like a firmware fault, not a power fault. Before you remove the old battery, run ActiveSync or Windows Mobile Device Center and confirm a full sync has completed.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMyPal shows a charging indicator but won't boot after a new battery is fitted\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA deeply depleted Li-ion cell can sit below the minimum boot voltage even after a short charge — the device draws power but the CPU never gets enough to start the boot sequence. This is not a faulty battery. Leave the unit on charge for at least 60 minutes before pressing the power button. If the charge LED is solid and the unit still won't boot, perform a hard reset by holding the reset pin for 10 seconds, then attempt boot with the charger still connected.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415954522202,"sku":"BWCS-AP696SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415954554970,"sku":"BWCS-AP696SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415954587738,"sku":"BWCS-AP696SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AP696SL-1.webp?v=1779758425","url":"https:\/\/batteryweb.com\/products\/asus-mypal-a686-replacement-battery-37v-1300mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
