It works fine, but 4 years from now is when a review like this needs to be written. I got a Power Sonic 12V 9AH and some Sigmas Tek 12V 9AH back in 2023. In 2026, the Sigmas Teks degraded quite a bit and it will run my computer UPS for 6 minutes, but the Power Sonic will run it for 20 minutes. Both brands were stored the same way with maintenance charging a couple times per year. The Power Sonic also has a lower float charge current which means it will over charge less and last longer in a UPS sitting at 13.6 Volts. Review: Perfect for exit light battery replacement - Work great in exit lights.
