The WEIZE Wise Series AUX14 is a small sealed AGM auxiliary battery: 12V, 14Ah, BCI Group 400, rated 200 cold cranking amps at 0°F. It is built for backup and auxiliary duty rather than engine starting — think secondary power for accessories, small electronics, or a reserve bank. Its low self-discharge (under 9% per three months) and wide operating temperature range suit vehicles and equipment that sit unused. Against larger Group 34/35 AGM batteries it trades cranking power and capacity for a compact footprint, so it fits where a full-size battery will not.
