benefits. First, the batteries output a constant 1.5V, the same as alkaline batteries, so you can use the Paleblue ones anywhere you\u2019d use regular batteries. Secondly, Li-ion batteries hold their charge for a long time, so you can pre-charge and have these batteries ready to go.<\/p>\n<p>While Trust sells its batteries in a two- or four-pack, the Paleblue AA USB-C Rechargeable Batteries are only available as a four-pack. Each set comes in a neat, hard plastic carry case, and comes with a four-way USB-C cable, so that you can charge all four batteries using just one USB-A outlet. <\/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-AA-USB-C-Rechargeable-Batteries-carry-case-1024x576.jpg\" alt=\"Paleblue AA USB-C Rechargeable Batteries carry case\" class=\"lazy lazy-hidden wp-image-4634143\"><figcaption class=\"wp-element-caption\">Image Credit (Trusted Reviews)<\/figcaption><\/figure>\n<p>With Trust, you only get the splitter in the four-pack of batteries.<\/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-AA-USB-C-Rechargeable-Batteries-USB-C-four-way-cable-1024x576.jpg\" alt=\"Paleblue AA USB-C Rechargeable Batteries USB-C four-way cable\" class=\"lazy lazy-hidden wp-image-4634147\"><figcaption class=\"wp-element-caption\">Image Credit (Trusted Reviews)<\/figcaption><\/figure>\n<p>Charging has to be performed using USB-C, as Li-ion batteries aren\u2019t compatible with standard battery chargers. In fact, trying to use a regular battery charger runs the risk that you\u2019ll damage the batteries. Some newer chargers, such as the XTAR XV4 are compatible with Li-ion, however.<\/p>\n<p>Using USB-C is probably the easiest option for most people. Once a cable is connected to the USB-C port on the battery, a green LED flashes to show that the cell is charging; the light goes solid green when fully charged.<\/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-AA-USB-C-Rechargeable-Batteries-charging-1024x576.jpg\" alt=\"Paleblue AA USB-C Rechargeable Batteries charging\" class=\"lazy lazy-hidden wp-image-4634145\"><figcaption class=\"wp-element-caption\">Image Credit (Trusted Reviews)<\/figcaption><\/figure>\n<p>Each battery has a 1700mAh capacity, the same as the Trust ones.
