I've been using these Henreepow rechargeable batteries for my outdoor solar lights for about 6 months now, and they've completely transformed my garden lighting situation.

The first thing I noticed was how they brought my old solar pathway lights back to life - the light output is noticeably brighter than with my previous batteries. I can actually see my garden paths at night now!

Charging through the solar panels works perfectly fine, though I did need to be patient during the first few days as they came only partially charged. Now they consistently last through the night even on cloudy days.

What really surprised me is how well they handle temperature changes. We've had everything from scorching summer days to freezing winter nights, and the batteries keep performing without issues.

The only minor drawback is remembering to fully discharge them occasionally - I set a calendar reminder every 3 months to do a complete cycle. But considering how much money I'm saving versus disposable batteries, it's absolutely worth it.

After trying several brands, these have become my go-to for all outdoor solar applications. They're particularly great for string lights where you need multiple batteries - the 12-pack is perfect for replacing all my garden lights at once.
