Are 12 volt lithium deep cycle batteries rechargeable?

Few years ago, it was very common to use nickel-cadmium and nickel-metal hydride rechargeable 12v 42ah Lifepo4 Batteries in mobile phones and notebook computers, but with the demand for lighter and smaller mobile devices for more energy, lithium batteries prevailed. The market dominance of lithium deep cycle batteries should be attributed to its being a light material. It is the third lightest metal in the periodic table of elements, which means that it can store more energy under the same weight and volume. Nowadays, you can find lithium batteries in laptops, cell phones, and iPads. With the emergence of electric vehicles and new solar storage systems using lithium batteries, this technology will exist for some time. Are 12 volt deep cycle lithium batteries rechargeable? How does it works? What are the advantages? This passage can give you a better understanding of lithium batteries.



Are 12 volt lithium deep cycle batteries rechargeable And How Does It Work?

Of course 12 volt lithium deep cycle batteries are rechargeable. A lithium polymer battery is a kind of rechargeable battery. This is an advanced battery technology, which uses lithium ions as its key component in electrochemistry. In order to generate energy, lithium ions move from the negative electrode to the positive electrode through electrolyte. In the discharge cycle, lithium atoms in the anode are ionized and separated from the electrons. The lithium ions move from the anode, pass through the electrolyte, and reach the cathode, where they recombine with electrons and undergo electrical neutralization. Because of lithium’s small size (third only to hydrogen and helium), they can move through a micro-permeable separator between the anode and cathode. Besides, the small size can help lithium batteries are capable of having a very high voltage and charge storage per unit mass and unit volume.

Compared with nickel-based systems, charging lithium batteries is much easier that the charge circuit is straightforward. Voltage and current limits are easier to adapt to than analyzing complex voltage signals, which change with the aging of the lithium polymer battery. Does not need saturation as is the case with lead acid, the charging process can be intermittent. For renewable energy storage like solar panels and wind turbines, it provides a major advantage as they cannot always fully charge the lithium polymer battery. Without trickle charging, the charger is simplified. Besides, lead-acid needs equalizing charger, but it is not necessary with lithium batteries.

What Are Some Advantages Of 12 volt lithium deep cycle batteries?

There are several important advantages for lithium batteries.

First of all, lithium ion deep cycle battery is usually much lighter than other rechargeable batteries of the same size. The electrodes are made of lithium and carbon with lightweight. Lithium is also a highly reactive element that it can store a lot of energy in its atomic bonds. That means tubular battery  has a very high energy density. For example, 1 kilogram of lithium battery can store 150 watt-hours of electricity. But a lead-acid battery can store only 25 watt-hours per kilogram. In another words, lead-acid technology need to take 6 kg to store the same energy as 1 kg of lithium battery.

In addition, lithium batteries can provide up to 3.6 Volts, which is 3 times higher than technologies such as nickel-cadmium or nickel-hydrogen. This means that they can provide a large amount of current for high-power applications, which require relatively low maintenance of lithium batteries and do not need to be periodically cycled to maintain their battery life.Sometimes, lithium car battery can also play an important role.

Thirdly, lithium batteries can hold their charge that the battery has a low self-discharge rate of around 1.5-2% per month, comparing with a 20% loss per month for NiMH batteries. It is environmental friendly that do not contain toxic cadmium, which makes them easier to dispose of.

Last but not least, lithium batteries no effects on memory. Memory effect is an adverse process, and repeated partial discharge/charging cycles can cause a battery to ‘remember “its lower capacity. The memory problems are caused by a build-up of crystals on the battery’s electrodes, which leave less and less room for chemical reactions to take place during charging. For lithium batteries, you do not need to like some other battery chemistries that have to completely discharge before recharging. And it also has capable of handling hundreds of charge and discharge cycles.

Because of these advantages, lithium batteries have replaced Ni-Cd batteries as the market leader in portable electronic devices. Lithium batteries are also used to supply power to electrical systems in new and more environmentally friendly aerospace applications. From the perspective of clean energy, most of the prospects of lithium technology come from its potential application in battery-driven vehicles.

Guidelines for Charging Lithium Batteries

Never put your battery on a charger and leave it unattended. That is, never charge the battery at night or leave the area for a long time. Check the “time required to fully re-charge” and plan to have someone be in attendance.

Turn off the equipment or disconnect the charging load, so that the current will drop unimpeded during saturation. A parasitic load can interfere with the charger.Sometimes, the lithium battery price is also a very important factor.

The temperature for charging is moderate. Please do not charge below the freezing point.

Lithium batteries do not need to be fully charged, partial charging is better. Not all chargers are fully charged, and when the “Ready” signal appears, the battery may not be fully charged.

If the battery is overheated, stop using the charger and/or the battery. The battery pack temperature rises more than 18 degrees Fahrenheit during normal charging, it is considered overheating.

Charge the empty battery before storage (40% state of charge is ideal).

Charging Lithium Batteries


Because deep cycle 12 volt lithium batteries contain positive and negative copper foils, electrolytes and the like generate chemical reactions by charging to store electrical energy, lithium batteries can chargeable. Compared to other battery technologies, it has a higher energy density, longer battery period, a faster charging speed, and safer use. It will properly have more spaces for development in the future.
