USB-C port built directly into each battery cell Charge both batteries at once with the included dual-end cable 4800mAh capacity per cell - for torches, lanterns, and radios 1.5V output matches standard disposable D-cell voltage Up to 1200 charge cycles per cell Charges in approximately 2.5 hours 36-month shelf life when stored Pack of 2 with charging cable included Manufacturer warranty: 1 year Lighthouse USB-C Rechargeable D Battery - Li-Ion 4800mAh Pack of 2 Built-in USB-C charging, no separate cradle required: Each battery in this Lighthouse two-pack has a USB-C port built directly into the cell, so you can charge it using any USB power source without a separate charging dock. The included dual-end USB-A to USB-C cable connects both batteries at once, and a charging indicator lets you monitor status as they top up. Charge time is approximately 2.5 hours, depending on the USB power source used. Li-Ion chemistry at a standard 1.5V output: These are Li-Ion cells rated at 1.5V and 4800mAh per battery, matching the voltage of conventional disposable D cells so they work in the same devices without adjustment. That capacity makes them well suited to high-drain equipment such as torches, lanterns, portable radios, and emergency lighting. Each battery is rated for up to 1200 charge cycles, and cells retain their charge for up to 36 months in storage. A practical alternative to disposable batteries: Over their lifespan, these rechargeable D cells replace a significant number of single-use batteries, reducing both ongoing costs and the number of cells going to waste. They are a straightforward swap for any device that takes standard D-size batteries.
