It matches the OEM part number 3AAA-HHC and fits the physical battery bay without modification. Capacity is rated at 2.52Wh, identical to the original cell specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eA08 and Trek Max platform fit:\u003c\/strong\u003e\n    Both models share the same 3.6V single-cell Ni-MH architecture, connector pinout, and physical footprint — 45.70 × 31.90 × 11.40 mm. Same battery bay, same charge circuit, same part.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the A08's onboard charge controller and confirmed the charge termination responded correctly at full capacity. The protection circuit tripped cleanly under a deliberate over-discharge test, with no thermal anomaly during recharge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eNi-MH cycle discipline on the A08:\u003c\/strong\u003e\n    The A08's charge circuit is calibrated for Ni-MH delta-V termination. Constant top-off charging without a full discharge at least once a month causes fuel gauge drift — the indicator reads full but actual capacity has declined. Run the speaker to below 20% once a month before recharging.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the A08 plays loud for a short time then cuts to low volume on a replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe A08's amplifier draws a current spike at high volume that the speaker's onboard protection circuit monitors against. A cell with internal resistance higher than the original spec causes voltage to sag sharply under that spike. The firmware interprets the sag as a low-battery event and throttles output to protect the cell. A fresh 3AAA-HHC cell with correct internal resistance holds the voltage rail steady under amp load, preventing premature throttling.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAudio distorting before the battery indicator reaches empty\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the A08, distortion before the low-battery warning usually means the cell's voltage is sagging under amplifier draw faster than the indicator updates. The indicator samples voltage at rest; the amplifier pulls current in bursts that the display doesn't capture. Measure the battery voltage under load with a multimeter — if it drops below 3.0V during playback, the cell is failing. Replace the cell and recheck; a healthy 3AAA-HHC cell should hold above 3.2V under normal playback draw.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416233279578,"sku":"BWCS-TKA008SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416233312346,"sku":"BWCS-TKA008SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416233345114,"sku":"BWCS-TKA008SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TKA008SL-1.webp?v=1779761074","url":"https:\/\/batteryweb.com\/products\/tdk-life-on-record-a08-replacement-battery-36v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
