Foremost, these batteries operate at a constant 1.5V, the same as alkaline batteries, whereas normal rechargeables are rated at a nominal 1.2V (typically, for NiMH batteries, they\u2019ll start at a higher voltage, which drops as the batteries drain).<\/p>\n<p>Secondly, Li-ion batteries hold their charge for a long time, so you can pre-charge these, store them and have them ready to go at near full capacity.<\/p>\n<p>Using Li-ion means that the Paleblue AAA USB-C Rechargeable Batteries are compatible with a wider range of devices, and you may see better performance out of them, such as constant light output from a torch.<\/p>\n<p>The slight downside is that these batteries can\u2019t be used with a standard battery charger. If you do, then you risk damaging the batteries. Instead, they should be charged via their USB-C port on top.<\/p>\n<section class=\"block block-mobile-ad block-mobile-ad-double\" style=\"height: 620px\">\n<div class=\"ad-label\" style=\"height: 20px\">\n        Advertisement    <\/div>\n<div class=\"ad-inner\" id=\"ad_mobile-in-article_2\"><\/div>\n<\/section>\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/www.trustedreviews.com\/wp-content\/plugins\/a3-lazy-load\/assets\/images\/lazy_placeholder.gif\" data-lazy-type=\"image\" data-src=\"https:\/\/www.trustedreviews.com\/wp-content\/uploads\/sites\/7\/2025\/12\/Paleblue-AAA-USB-C-Rechargeable-Batteries-USB-C-port-1024x576.jpg\" alt=\"Paleblue AAA USB-C Rechargeable Batteries USB-C port\" class=\"lazy lazy-hidden wp-image-4634728\"><figcaption class=\"wp-element-caption\">Image Credit (Trusted Reviews)<\/figcaption><\/figure>\n<p>Usefully, Paleblue includes a four-way USB-C cable in the box, which can charge all four batteries in the pack using a single USB-A port.<\/p>\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/www.trustedreviews.com\/wp-content\/plugins\/a3-lazy-load\/assets\/images\/lazy_placeholder.gif\" data-lazy-type=\"image\" data-src=\"https:\/\/www.trustedreviews.com\/wp-content\/uploads\/sites\/7\/2025\/12\/Paleblue-AAA-USB-C-Rechargeable-Batteries-USB-C-cable-1024x576.jpg\" alt=\"Paleblue AAA USB-C Rechargeable Batteries USB-C cable\" class=\"lazy lazy-hidden wp-image-4634727\"><figcaption class=\"wp-element-caption\">Image Credit (Trusted Reviews)<\/figcaption><\/figure>\n<p>This cable and the batteries all come in a hard plastic carry case, which makes these batteries neat to store or carry around.
