XTAR L4 Pro Review: Can It Save Your Old Batteries? 🔋

This is a first impressions review of the Xtar L4 Pro NiMH and Li-Ion Battery charger. Looking for a way to breathe new life into your old batteries? In this XTAR L4 Pro review, I test its smart charging features to find out if it really can save aging batteries like my 20-year-old Eneloops. This compact charger handles both lithium-ion and nickel-metal hydride batteries, offering modes like charge, discharge, and refresh to maximize battery capacity safely and efficiently. Whether you're looking for a reliable travel charger or a solution for reviving older cells, the XTAR L4 Pro might be what you need. Throughout the video, I put this charger to the test, comparing it to my trusty Annsman 16 and evaluating its ability to refresh batteries that most chargers give up on. With USB-C compatibility, a simple interface, and a focus on reducing heat for safer charging, this device is designed for functionality and longevity. However, it’s not about speed—this charger prioritizes battery health over rapid charging. If you’re interested in a portable, no-frills solution for refreshing old batteries or upgrading your current charging setup, this might be worth considering.
