The protective circuit, which includes several safety features, is now located at the battery&#8217;s anode end (+). Thanks to this, the battery can now, for the first time, be covered with a steel cylinder casing that protects the battery from external harmful dents and impacts. The steel cylinder casing makes the battery extremely safe and prevents battery damage that may be caused by external dents and impacts.<\/p>\n<p>The battery&#8217;s best possible performance is ensured by a quadruple protection mechanism. The battery has multiple protections against overheating. Additionally, the battery is protected against overcharging, overdischarging, and possible short circuits. This Fenix ARB-L18-3500 Li-ion battery does not exhibit the so-called harmful memory effect, so charging is worry-free. The battery has an extremely low self-discharge rate even if stored unused for long periods. Fenix ARB-L18-3500 is one of the most modern and safest high-capacity Li-ion rechargeable batteries on the market.<\/p>\n<p><strong>Features:<\/strong><\/p>\n<\/p>\n<ul>\n<li>Type: 18650<\/li>\n<\/ul>\n<ul>\n<li>Nominal voltage: 3.6 V<\/li>\n<\/ul>\n<ul>\n<li>Capacity: 3500 mAh<\/li>\n<\/ul>\n<ul>\n<li>Charging current: recommended 1A, max. 2A<\/li>\n<\/ul>\n<ul>\n<li>Advanced protection circuit<\/li>\n<\/ul>\n<ul>\n<li>Steel protective structure effectively protects the battery from possible short circuits caused by impacts and other hazards<\/li>\n<\/ul>\n<ul>\n<li>Size: 18.6 x 69 mm<\/li>\n<\/ul>\n<ul>\n<li>Button top positive terminal and flat negative terminal<\/li>\n<\/ul>\n<ul>\n<li>Weight: 50 g<\/li>\n<\/ul>\n<ul>\n<li>Warranty: 12 months<\/li>\n<\/ul>\n<ul>\n<li>Charger recommendation: Fenix ARE-X1, ARE-X2, Fenix ARE-C2<\/li>\n<\/ul>\n<ul>\n<li>Package: 1 pc <\/li>\n<\/ul>\n<p class=\"\">18650 battery standard batteries come in various models and lengths. Some batteries, like this product, have a built-in protection circuit that prevents overcharging and excessive discharging. Because of the protection circuit, the battery is slightly longer than batteries without a protection circuit. Additionally, the battery terminals have either raised (button top) or flat ends. Ensure the battery fits your device by carefully measuring the original battery.<\/p>\n","protected":false},"excerpt":{"rendered":"<ul>\n<li>Steel cylinder structure<\/li>\n<li>On the protective circuit<\/li>\n<\/ul>\n","protected":false},"featured_media":999999999,"template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[16800,36799,37317,17230,19920,39510,36803,16802],"product_tag":[],"class_list":["post-1337673","product","type-product","status-publish","has-post-thumbnail","product_cat-patareid-akud-ja-laadijad","product_cat-batteries-accumulators-and-chargers-en","product_cat-barefoot-and-gatekeepers-en","product_cat-telakat-ja-porttitoistimet","product_cat-office","product_cat-office-en","product_cat-rechargeable-batteries-en","product_cat-ladattavat-akkuparistot","first","onbackorder","taxable","shipping-taxable","purchasable","product-type-simple"],"acf":[],"_links":{"self":[{"href":"https:\/\/digibit.ee\/en\/wp-json\/wp\/v2\/product\/1337673","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/digibit.ee\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/digibit.ee\/en\/wp-json\/wp\/v2\/types\/product"}],"wp:attachment":[{"href":"https:\/\/digibit.ee\/en\/wp-json\/wp\/v2\/media?parent=1337673"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/digibit.ee\/en\/wp-json\/wp\/v2\/product_brand?post=1337673"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/digibit.ee\/en\/wp-json\/wp\/v2\/product_cat?post=1337673"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/digibit.ee\/en\/wp-json\/wp\/v2\/product_tag?post=1337673"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
