tyrone 4 Pack 18500 Rechargeable Batteries,18500 Button top Rechargeable Batteries for Flashlight, Solar Garden, [ More Than 1500mAh 3.7V Batteries with 2-Ports Smart Charger ]

Even though the charger's instruction manual does not list comparability with these 18500 3.7V Li-ion batteries, Tyrone Customer Service replied that this charger will work perfectly with these batteries, and it does . The batteries do not overheat and charging stops at 4.2V as designed. This set will allow me to maintain my yard solar lights during winter's short daylight hours. Both batteries and charger are simple but effective and well made.

I really like the design and its very slick, looks modern and the material is sturdy. Nothing is juggling, everything is in place. For the charging it fast in the fastest safe charging speed. It has a screen that show the battery level for each battery separately which is cool. And the best part that it get its power from USB C cable, so you can plug in anything including a power bank.

We used for our solar light that lights our American flag… these batteries were perfect!

Only used once but the charging was fast

Fit perfect.

Haven't had it long enough to know about Longevity. But, it charges good.

I sometimes have a problem finding the battery size. These batteries came with a charger too!

This charger holds the odd sized batteries inside many of my outdoor solar garden lights. After a while the batteries need to be recharged. I am simply pull them out, recharge them and put them back in they are good to go. The charger seems to work pretty fast and so far the batteries hold a charge well.
