Ellie X. ★★★★★

I was a bit skeptical about third-party batteries, but this one snapped right into my Velux unit and the 2000mAh capacity has been holding a charge noticeably longer than the original.

Chloe ★★★★★

Finally got around to swapping out the old battery and the 2000mAh capacity has my Velux light staying bright well past dusk. Installation was straightforward and it fit perfectly.

Amelia B. ★★★★★

After two weeks of cloudy weather my Integra solar blind just quit, so I ordered this 2000 mAh replacement and it dropped right in. It's been running the blind up and down daily for a month now without needing a charge.
