AGM batteries cost less per amp, or per “battery size,” than lithium batteries. For example, an average current price for a 100-amp-hour LiFePO4 battery is about $700, whereas the same size AGM ...

Life test measures how a battery endures repeated charge-and-discharge cycles at hot-climate engine-compartment temperatures. The more cycles endured while maintaining a higher voltage, the higher ...
