This makes the charger widely applicable for various brands of e-bikes. <\/p>\n<p><strong>Fast charger 4 amps<\/strong><\/p>\n<p>The 4A (4 amps) designation indicates the charging current, or the speed at which the battery is charged. Standard chargers only deliver 2A charging current. In practice, this means a 13Ah battery will take just over 3 hours to fully charge compared to over 6 hours with a standard charger.  <\/p>\n<p>Most batteries are suitable for 4A charging, but please check this beforehand. Charging with a higher amperage can lead to extra wear and a shorter battery life if the battery is not suitable for it. <\/p>\n<p><strong>Reliable quality as originally supplied<\/strong><\/p>\n<p>This charger is produced by Sans, the OEM manufacturer that supplies chargers for various European e-bike brands. This means you are choosing a charger with the same technology and reliability as the chargers standardly supplied by bike brands with their batteries. <\/p>\n<p><strong>Why a 42V charger belongs with a 36V or 37V battery<\/strong><\/p>\n<p>Although the battery says 36V or 37V, an e-bike battery is charged to approximately 42V when fully charged. This is because the lithium cells in the battery are each charged to 4.2V: 10\u00d74.2=42. Therefore, 36V &#038; 37V batteries in this category use a 42V charger.  <\/p>\n<p><strong>Charging e-bike batteries &#038; extending lifespan<\/strong><\/p>\n<p>How you charge and use an e-bike battery has a major impact on performance and lifespan. By handling charging and storage smartly, you prevent unnecessary wear and get the most out of your battery. <\/p>\n<p>Read everything about e-bike battery charging and battery management <a href=\"https:\/\/rap-webshop.nl\/en\/use-and-management-of-the-li-ion-bicycle-battery\/\" target=\"_blank\" rel=\"noopener\">HERE<\/a>.<\/p>\n<p><strong>Charger not working? How to identify the problem <\/strong><\/p>\n<p>Does your charger seem to have stopped working or is your battery not charging (properly)? In many cases, it is not immediately clear whether the problem lies with the charger or the battery. Causes can range from a defective plug or damaged cable to a fault in the battery or charger itself.  <\/p>\n<p>Not sure where the problem lies?
