If your device has a square 97mm battery compartment with spring contacts and requires 6V, the PJ996 is likely the correct replacement.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow does zinc chemistry differ from alkaline?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eZinc batteries provide lower peak current than alkaline equivalents but maintain more stable voltage under low to moderate drain. They suit devices with filament bulbs and mechanical switches better than high-intensity LED torches, which benefit from alkaline chemistry.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow long does the PJ996 last?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eRuntime depends on the device's power draw. In a typical camping lantern drawing 0.5-1W, expect several hours of continuous use or weeks of intermittent evening use. Heavier-draw devices will deplete the battery faster.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the battery rechargeable?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. The PJ996 is a primary (single-use) zinc cell. Attempting to recharge it risks leakage or rupture. Dispose of depleted cells at a battery recycling point.\u003c\/p\u003e","brand":"Eveready","offers":[{"title":"Default Title","offer_id":51783314505995,"sku":"S4682","price":4.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/S4682_1_454be292-7422-41da-8209-8cec06257b92.jpg?v=1750876614"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/collections\/New_menu_images_9.png?v=1782899951","url":"https:\/\/niori.co.uk\/collections\/speciality-batteries.oembed","provider":"Niori","version":"1.0","type":"link"}
