It carries OEM part number 253211 and matches the original cell format at 55.84 x 52.12 x 14.09mm. Swap it into any TGA or TGB remote that uses the 253211 form factor.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTGA and TGB compatibility:\u003c\/strong\u003e\n    Both remotes share the same 6V supply rail, connector footprint, and charge management circuit, which is why a single cell format — 253211 — covers both units without 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 a TGA remote. The BMS accepted the Ni-MH pack immediately on insertion, and the charge circuit completed without fault flags or cutoff interruptions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMonthly charge during crane downtime:\u003c\/strong\u003e\n    If the crane remote sits unused for weeks — common during seasonal shutdowns or equipment rotation — charge the battery once a month. Ni-MH cells that sit discharged too long lose capacity through self-discharge and may not recover full voltage even after a full charge cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSolenoid activation causing power dropout on a freshly installed battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen a TGA or TGB remote triggers a crane solenoid or relay, the inrush current spikes briefly above the steady-state draw. If the replacement cell's internal resistance is elevated — common when a Ni-MH pack ships at storage charge — the voltage can dip enough to trip the remote's undervoltage cutoff. The unit goes dark mid-command, which looks like a dead battery even though the cell isn't discharged. The fix is straightforward: charge the battery fully before the first use, so internal resistance drops to its normal operating level and the cell can absorb the solenoid inrush without a voltage sag below the cutoff threshold — typically around 5.0V for a 6V Ni-MH pack.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRemote showing low-battery indicator immediately after cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA freshly installed 253211 cell often reads as low battery right after insertion. This happens because Ni-MH packs ship at storage voltage — roughly 5.4–5.6V — not full charge voltage of around 7.2V peak open-circuit. The remote's fuel gauge reads the resting voltage and flags it as depleted. Put the remote on the Hetronic charger for a full cycle before drawing any conclusions about the replacement cell. Once the pack reaches full charge, the low-battery indicator should clear and the remote will operate normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360078397530,"sku":"BWCS-FUB03BL-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360078430298,"sku":"BWCS-FUB03BL-2","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360078463066,"sku":"BWCS-FUB03BL-3","price":38.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FUB03BL-1.webp?v=1778610859","url":"https:\/\/batteryweb.com\/products\/hetronic-tga-replacement-battery-6v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
