LiFePO4 batteries often come with a higher price tag, but a much better cost over life of the product. No maintenance and super long life makes them a worthwhile investment and a smart long-term solution. Safety Drop-in Replacement Lightweight Longest Life More Usable Capacity Constant Power Temperature Tolerant Charging - Fast & Safe PSOC Tolerant Long Shelf Life Maintenance Free Non-Hazardous Lithium is Long-Lasting Lifepo4lithium batteries provide up to 10 times longer life than lead-acid batteries, and they still provide 80% of rated capacity after 2,000 cycles. Most lithium-ion batteries last five years or more. The average lead-acid battery lasts just two years. Lead-acid batteries also need to be maintained, requiring water replacement to avoid structural damage; if they aren’t maintained properly, their life span is shortened even further. Because lithium batteries require no active maintenance, a one-time purchase guarantees longevity. Lithium is Quick & Efficient Lithium can charge and discharge at a high rate providing maximum versatility for all types of applications. Fast charging minimizes downtime, and lithium’s high rate of discharge is perfect for a burst of power. Lead-acid batteries must be charged in stages over a longer time, and they perform inefficiently during high discharge periods, making them less versatile than their lithium counterparts. Lithium’s efficiency is unparalleled, especially under high-stress situations. Unlike lead-acid, temperature fluctuations and energy depletion barely affect lithium’s power delivery. Lithium is the logical choice for applications that will exhaust the batteries or run in extreme weather. Lithium is the Lightweight Champ RELiON LiFePO4 batteries provide more energy than lead-acid batteries and are typically half the mass, reducing concerns about battery weight. Compared to other battery chemistries, lithium provides the same or greater energy at less than half the weight and size. This means more flexibility and easier installation! the battery in a cool dry surrounding if it stands by. Does not use or leave the battery near a heat source as fire or heater Use the battery charger specifically for that purpose when recharging. Do not reverse the position and negative terminals. Do not connect the battery electrodes to an electrical outlet. Do not discard the battery in fire or a heater. Do not short-circuit the battery by directly connecting the positive and negative terminals with metal objects. Do not transport or store the battery together with metal objects such as hairpins, necklaces, etc. Do not strike, trample or throw the battery. Do not directly solder the battery and pierce the battery with a nail or other sharp objects Battery Quality: 1. Cells - A grade cells to make sure batteries in high and full capacity 2.
