Best Alternatives to CSB UPS 12580 Battery

The CSB UPS 12580 battery is a VRLA (valve regulated lead acid) AGM (absorbed glass mat) battery that is very popular for UPS applications. This 12V 9AH battery can handle 130 A max discharge for 5 seconds as well as 95.1A current load for 2 minutes. It also has a 908W power capability for two minutes. There are few batteries on the market that can deliver such high performance.

In today’s world, many customers are looking for second sources and alternatives to products that are in short supply or have long lead times. Some potential alternatives include the Powersonic PSH-12100F2-FR, the Powersonic PHR1236 and Yuasa’s NPX-35L. Below is a comparison of their performance.

CSB has always been a frontrunner when it comes to maximum currents. Powersonic and Yuasa batteries provide enough power for many applications, and they have shorter lead times and product availability. Many companies are now considering Powersonic and Yuasa as viable alternatives.
