It replaces OEM part number 3201013 and restores full handset operation when the original cell can no longer hold a charge. Voltage and capacity match the original factory specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMA-240 and MH-200 compatibility:\u003c\/strong\u003e\n    Both models share the same 3.6V Ni-MH cell format, connector orientation, and BMS charge-acceptance profile — which is why a single part number covers both handsets.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through charge and discharge on a Ni-MH compatible test rig. The cell accepted charge without thermal spike and the BMS handshake with the base station completed normally across three consecutive cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge conditioning on Ni-MH handsets:\u003c\/strong\u003e\n    After installing, seat the handset in the base cradle and leave it for a full 16 hours before first use. Ni-MH cells shipped in a partial-discharge state need one slow charge to reach rated capacity — skipping this step will make the battery appear weaker than it actually is.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the MA-240 base station shows no charge light after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells lose voltage during storage. If a replacement cell arrives below roughly 3.0V, the MA-240 base station may not detect it as a valid pack and will withhold charge current entirely. The fix is straightforward — leave the handset seated in the base undisturbed for 30 to 60 minutes. Most base stations will begin a trickle top-up at that point, and once the cell climbs above the acceptance threshold, normal charging resumes automatically.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time shorter than expected after fitting a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a normal Ni-MH conditioning behaviour, not a fault with the cell. Fresh Ni-MH batteries do not reach full rated capacity on the first charge cycle — it typically takes three to five full charge-and-use cycles before the 700mAh rating is consistently available. Each cycle should end with the handset fully discharged through normal use, then returned to the base for a complete charge. After cycle five, talk time should stabilise at the rated level.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339948032090,"sku":"BWCS-BT930CL-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339948064858,"sku":"BWCS-BT930CL-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339948097626,"sku":"BWCS-BT930CL-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BT930CL-1.webp?v=1778366983","url":"https:\/\/batteryweb.com\/products\/casio-ma-240-replacement-battery-36v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
