This 4-pack comes pre-charged and ready to use straight from the blister pack, removing the need to charge before first use. Each cell can be recharged up to 500 times according to JCB, making them a reusable alternative to single-use alkaline AAA cells.\u003c\/p\u003e\n\u003cp\u003eDesigned for low-to-medium drain devices, these batteries suit wireless keyboards, TV and audio remotes, LED torches, wall clocks, portable radios and small battery-powered toys. The 650mAh capacity provides adequate runtime for devices that draw low continuous current, though high-drain devices like digital cameras or gaming controllers may drain the cells faster than alkaline equivalents. The batteries hold charge when stored, with JCB claiming they retain approximately 80% capacity after 12 months on the shelf.\u003c\/p\u003e\n\u003cp\u003eThe AAA HR03 form factor matches standard AAA sizing (10.5mm diameter, 44.5mm length), so the batteries fit any device designed for AAA cells. NiMH chemistry means the nominal voltage is 1.2V rather than the 1.5V of alkaline cells, which is sufficient for most electronics but may result in shorter runtime in voltage-sensitive devices. The cells can be recharged in any NiMH-compatible AAA charger (sold separately).\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.06\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery Range\u003c\/td\u003e\n\u003ctd\u003eJCB Rechargeable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCell Size\u003c\/td\u003e\n\u003ctd\u003eAAA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCell Composition\u003c\/td\u003e\n\u003ctd\u003eRechargeable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eHow many times can these batteries be recharged?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eJCB rates these batteries for up to 500 recharge cycles. Actual cycle life depends on how deeply the batteries are discharged before recharging and the charging method used. Frequent partial discharges followed by recharging can extend cycle life compared to deep discharge every time.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo they come charged?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. The batteries are pre-charged at the factory and ready to use immediately. However, if they have been stored for several months before purchase, they may benefit from a top-up charge before first use to restore full capacity.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat charger do I need?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAny NiMH-compatible AAA battery charger will work. Do not use chargers designed only for alkaline or lithium cells, as they may damage NiMH batteries or fail to charge them properly. Multi-chemistry chargers that detect cell type are the safest option.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy is the voltage 1.2V instead of 1.5V?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNiMH rechargeable batteries have a nominal voltage of 1.2V, compared to 1.5V for non-rechargeable alkaline cells. Most devices tolerate this difference without issue, but voltage-sensitive devices like some older cameras or portable audio players may show reduced runtime or low-battery warnings earlier than with alkaline cells.\u003c\/p\u003e","brand":"JCB","offers":[{"title":"Default Title","offer_id":46074429276427,"sku":"S17189","price":2.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/S17189_1_d48ce7c9-3412-42d9-92ac-cbc157294440.jpg?v=1730313584","url":"https:\/\/niori.co.uk\/products\/jcb-aaa-hr03-rechargeable-batteries-650mah-nimh-4-pack","provider":"Niori","version":"1.0","type":"link"}
