4 Slots Smart AA/AAA Charger with LED Flashlight + 4pcs 1.5v 1100mWh Li-Polymer Lithium Rechargeable AAA Battery

Seems to work GOOD.I have not recharged the batteries after use so I don't know how long they work (between charges) compared to non-rechargeable batteries.That just means you may need to change them out and recharge them a little more often then you would be replacing normal batteries.Using new non-rechargeable batteries is a "Big Waste of Money".You never know what the shelf life of a non-rechargeable battery is.I have purchased non-rechargeable batteries at many locations andthe amount of time they last are well below what it should be.

Love the batteries, they are true 1.5 volt not the 1.2V like nickel metal hydride NiMhThey seem pricey but they last and last and then you just recharge them.

I have these in my Garmin 680T. They work well. I have no complaint. About 8 hour run time. And then swap the other two into the unit.
