Performance Notes and Warranty:
STM does not warranty batteries. We offer the STM Lifetime Guarantee on the STM Battery Tray, but we cannot warranty the batteries themselves and any attempt we have made to have them warrantied by the manufacturer has been denied. The typical life we get from one of these batteries varies from 2 to 10 years. Expect to treat this battery as a maintenance item – once it’s done, just get a new one.

For a typical 300-600 HP street car, it’s fine to sit for 2 weeks to a month, drive and race on the weekends or drive everyday in nice temperatures (40-90°). If it sits longer than 3 weeks or if it’s in freezing temps, we recommend keeping the charger handy. This battery will handle normal audio systems, a subwoofer and mild accessories like lighting or alarms. It’s probably not suited for additional amps or more than one sub.

We have not encountered any performance issues with cranking. These 925 batteries are significantly more powerful than the smaller 680 and honestly these 925’s make a great lightweight option for a daily driven street car. Read more about the battery:
