The 12 Volt 20ah Battery is a high-performing lithium deep cycle battery designed for long-term use in various residential and commercial power applications. These batteries are made with Lithium Iron Phosphate (LiFePO4) cells and offer significant advantages over sealed lead acid (SLA) batteries, such as higher cycling life, superior recharge and discharge efficiency, and improved temperature protection.
The LiFePO4 battery is also 100% maintenance free, requiring no water addition and can be mounted in any position. The battery can be charged at any voltage and does not produce toxic fumes when charging or discharging. Moreover, this battery has a lower self-discharge rate and can be stored at cooler temperatures, which further enhances its lifespan. This battery is highly durable and offers a great value for money as it has a 10-year warranty, which is double the standard warranty of most batteries on the market.
Our 12V 20AH Lithium Battery has a built-in BMS (Battery Management System) that monitors the key operational parameters of the battery during charging and discharging, such as cell voltage, currents, internal temperatures, and more. This ensures that the battery is always at peak performance and prevents overcharging, overheating, short circuit, and more. This makes it the perfect choice for your residential or commercial power needs.
Unlike traditional lead acid batteries, this high-performance 12V 20Ah LiFePO4 Battery is 100% maintenance-free and can be mounted in any position. It is also safe to operate, even in non-ventilated battery boxes. Furthermore, this battery does not produce toxic gases during charging or discharging, which is a major advantage in applications where space is limited.
This battery is designed to be a drop-in replacement for old generation lead VRLA, AGM or OPZ batteries in 12V, that are both low in performance and harmful to the environment (use of heavy metals and acid electrolytes). This Lithium Battery has been engineered with advanced rhombus cells with patented Lithium Iron Phosphate chemistry, offering high-level safety through multi-stage cell design and a quadruple energy density for an equivalent size and weight.
MillerTech PREMIUM lithium batteries are manufactured with Grade A lithium iron phosphate cells, which means they will last over 3,000 cycles at a full charge and a full discharge or more. This is significantly more than the average SLA battery and makes it one of the most cost-effective options for your power application. Each battery is backed by our 5-year replacement and repair warranty. This means that in the unlikely event of a problem, we will replace or repair it at no additional cost to you. This includes shipping, handling, and the installation of the new battery in place of your existing one. This warranty does not cover the normal end of life of the battery that will occur naturally over time depending on the application. 12 volt 20ah battery
