The TELME TS100 is a senior-focused handset built for calls and basic messaging. When the original cell no longer holds a charge or the phone shuts down unexpectedly, this cell slots directly into the battery bay.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTELME TS100 and TS100S compatibility:\u003c\/strong\u003e\n    Both models use the same battery bay dimensions and connector pinout, pulling from the same AK-TS100 cell. The BMS handshake is identical across both variants, so one SKU covers both.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the TS100 platform. The BMS communicated cleanly with the charge IC on every cycle, and protection cutoffs triggered correctly at both the low-voltage floor and the charge termination ceiling.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On first use after installation, disable fast charging if available and run one full discharge-to-charge cycle. This lets the fuel gauge IC map the new cell's discharge curve before logging percentage readings — skipping this step causes the OS to report inaccurate battery levels for the first several cycles.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the TS100 after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC is still calibrated to the old cell's discharge curve. A fresh cell has a slightly different voltage-to-capacity slope, so the IC calls 20–30% when the actual cell voltage is already close to the BMS cutoff floor. Under the load of an active call or screen-on state, the voltage dips below the cutoff and the phone shuts off. One full discharge cycle — draining to auto-off, then charging to 100% uninterrupted — forces the coulomb counter to reset against the new curve. After that cycle, percentage readings stabilise.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone warm near the battery compartment on the first charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new cell comes with higher internal impedance than a used one that has been through hundreds of cycles. On the first charge, the charge IC pushes current into a cell that hasn't yet settled to its working impedance, and that resistance converts some energy to heat. This is normal and typically resolves within two to three charge cycles as impedance drops. If the phone remains hot to the touch beyond the third charge or the housing feels hot rather than warm, remove it from charge and check that the battery is seated flat with no physical bulge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404279119962,"sku":"BWCS-EAC100SL-1","price":15.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404279152730,"sku":"BWCS-EAC100SL-2","price":16.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404279185498,"sku":"BWCS-EAC100SL-3","price":17.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-EAC100SL-1.webp?v=1779369550","url":"https:\/\/batteryweb.com\/products\/emporia-telme-ts100-replacement-battery-37v-1150mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
