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 ]

Only used once but the charging was fast

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.

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.

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

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

I use these for my solar landscape lightingLove how they hold a brighter charge longer!

The charger works great. I like that I can see the amount of charge the battery has as it charges.

Like that you can see how much charge the battery has on charger. Batteries seem fine so far.
