What Is The Best 12 Volt Lithium Battery?

12-volt lithium batteries are becoming more and more common in various deep cycle applications thanks to their lightweight design, excellent deep cycle performances, a large number of charging/discharging cycles, etc., and are being offered in various sizes with different features by the ever-increasing number of companies.

The list of 12V lithium batteries suitable for use as off-the-grid, RV, trolling, golf cart, etc. batteries is quite long, but there are few models that have distinguished themselves among the others due to their features, but also, the price.

12V Lead-Acid Batteries vs 12V Lithium Batteries

12V lead-acid batteries are typically wet/flooded, AGM (Absorbent Glass Mat) and Gel-Cell batteries, with 6 (six) 2V cells connected in series in order to achieve 12V nominal voltage.

They are heavy, support a limited number of charging/discharging cycles, can provide huge currents (even deep cycle lead-acid batteries when shortcircuited), they are cheap and reliable.

For short, lead-acid batteries:

- wet/flooded: not maintenance-free batteries, not spill-proof, can operate only in upside position, can be recharged in 8-15 hours,

- Gel-Cell: maintenance-free, spill-proof batteries that can operate in any position except up-side-down, can be recharged in 6-10 hours,

- AGM: maintenance-free, spill-proof batteries that can operate in any position except up-side-down, can be recharged in 5-7 hours.

12V lithium batteries are mostly Lithium Iron Phosphate (LiFePO4) batteries featuring 4 (four) 3.2V cells connected in series in order to achieve a nominal voltage of 12.8 volts.

The main advantages and disadvantages of 12-volt lithium batteries include:

Number of Charging/Discharging Cycles: depending on the depth of discharge, deep cycle lithium batteries can withstand 2000-3000 charging/discharging cycles down to 100% DoD (Depth of Discharge), 3000-4000 charging/discharging cycles down to 80% DoD, with some models supporting 6000-7000+ charging/discharging cycles down to 50% DoD.

On average, lead-acid batteries support 180-250 charging/discharging cycles down to 100% DoD, 250-300 charging/discharging cycles down to 80% DoD, and 400-600 charging/discharging cycles down to 50% DoD, with some very rare models supporting 1000+ charging/discharging cycles down to 50% DoD.

On average, lithium batteries support 7-10 more charging/discharging cycles than lead-acid batteries.

High-Discharge Current Capacity Loss: lithium batteries don't suffer from capacity loss when being discharged with stronger currents, at least not as much as lead-acid batteries.

For example, most lithium batteries when being discharged with ~1C currents feature a capacity drop of a few percent and can be discharged with 1C currents for almost one hour.

On the other hand, when lead-acid batteries are discharged for one hour, their actual capacity drops down to 55-72% of their nominal (20h) capacity. And when they are discharged with 1C currents, their discharge time is much shorter than one hour - usually around 30-40 minutes.

Ultralight Design: On average lithium batteries are 2-3x lighter than lead-acid batteries of the same nominal capacity.

However, when the batteries are being discharged with stronger currents, for example, 0.5-1.0C, due to the capacity loss of the lead-acid batteries, lithium batteries are at least 3-5x lighter than lead-acid batteries.

Safety Issues: wet/flooded lead-acid batteries should be placed in well-ventilated areas in order to avoid the buildup of highly flammable hydrogen gas.

Even AGM and Gel-Cell lead-acid batteries feature safety pressure valves that open, if required, and release excess hydrogen and oxygen in order to prevent gassing out of the batteries - this happens if the batteries are being charged with two strong currents or if the batteries are being overcharged.

On the other hand, lithium batteries release no dangerous gasses during operation.

However, in order to prevent issues with the lithium batteries, they feature built-in Battery Management Systems (BMS) that protect the batteries from unwanted events like overcharging, over-discharging, overcurrent, high/low temperature, and similar.

Also, a very important BMS task is to equalize the cells periodically.

If the BMS detects the unwanted event, it disconnects the battery, preventing possible damage, which is great, in most situations.

On (very) rare occasions, a glitch in the electric system may be considered as an unwanted event (false positive), causing the BMS to disconnect the battery. Depending on the type of event, BMS can automatically reconnect the battery, but that is not always 100% sure.

Charging: lead-acid batteries accept charge very well and can be recharged using various chargers with various charging algorithms.

But, in order to prolong the operating life of the lead-acid battery chargers, it is highly recommended to recharge them using advanced battery chargers that are microprocessor-controlled.

Such chargers allow the user to set the exact battery chemistry (wet/flooded, AGM, Gel-Cell) and battery usage (Cycle or Float/Standby).

Before actual charging, such chargers analyze the battery and adjust the charging algorithm according to the battery condition - if required, they include Desulfation Mode and Equalization Mode and after the battery is fully recharged, they automatically switch to Maintenance Mode.

On the other hand, 12V lithium batteries should be recharged with the dedicated lithium battery chargers or with the advanced lead-acid battery chargers that also feature dedicated lithium battery charging mode.

Note: If an advanced lead-acid battery charger tries to "desulfate" lithium battery, it may damage/destroy the BMS, practically destroying the lithium battery.

While lead-acid batteries may be recharged with 0.1-0.2C currents, most of the lithium batteries accept 0.5-1.0C charging currents, with 0.25-0.5C currents being recommended.

For example, a 12V 20A lithium battery charger can recharge a 12V 100Ah lithium battery discharged down to 50% DoD in under 3 hours, with no stress to the battery.

Maintenance: wet/flooded lead-acid batteries are not maintenance-free batteries, while AGM, Gel-Cell, and Enhanced Lead-Acid batteries are, more or less, maintenance-free batteries.

12V lithium batteries are practically maintenance-free, spill-proof batteries that can operate in practically any position, up-side-down included.

Connecting in Parallel and Series: As long as the lead-acid batteries are of the same model and of a similar age (preferably from the same batch), they can be connected freely in parallel and/or series.

On the other hand, lithium batteries can be connected in parallel and/or series only if explicitly permitted by their manufacturer - even then, one should use batteries of the same model and of the same age, preferably of the same batch.

Good lithium battery supports connecting 4P and/or 4S - 4 (four) batteries in parallel and/or 4 (four) batteries in series (also known as 4S4P configuration).

Note that some models allow making even larger battery packs.

Price: lead-acid batteries are initially cheaper than lithium batteries of the same capacity. However, considering their much larger number of charging/discharging cycles and the weight savings, lithium batteries are in the long run cheaper, especially in the applications where the batteries are cycled regularly.

Of course, there are other lithium battery advantages and disadvantages, when compared with lead-acid batteries, but these are the most important ones.

How to choose the best lithium battery for your needs?

Well, put on paper what kind of battery or battery pack You need and start from there. After that, check the batteries with suitable capacity, discharge features, and allowed parallel/series connectivity and work toward your ideal battery - your best 12V lithium battery.

Taking into account all pros and cons, there are several batteries that really stand out, including two: Battle Born BB10012 and Ampere 12V 300Ah battery (Amazon links, open in the new windows). 

The Best Overall 12V Lithium Battery

battleborn bb10012 w300px

Battle Born BB10012 battery is probably the best or among the best 12V lithium batteries.

It weighs only 29 pounds (13.2 kg), has a very constant output voltage, with the maximum continuous output current of 100 Amps, providing up to 200 Amps for 30(!) seconds and thanks to the excellent BMS, it supports connectivity of four batteries in parallel and/or four batteries in series.

Physical dimensions of the battery are (L x W x H) 12.75 x 6.88 x 9 inches (~32.4 x 17.5 x 22.9 cm) - Battle Born BB10012 battery belongs to the BCI Group 31.

Battle Born BB10012 battery is one of the most used lithium batteries for various applications, including solar, RV, off-the-grid, for electric vehicles, trolling motor battery, etc.

The battery supports at least 3000 charging/discharging cycles using currents in the 0.5C range.

Battle Born BB10012 battery comes with a 10-year limited warranty - charge it properly, don't abuse it (too much), don't hit it with a hammer and this battery will serve You for a long time. 

The Best High-Capacity 12V Lithium Battery

amperetime lithium 12v 300ah

 

Ampere Time 12V 300Ah deep cycle lithium battery is one of the best, if not the best, high-capacity 12V lithium battery.

Ampere Time 12V 300Ah lithium battery features physical dimensions of (L x W x H) 20.47 x 10.59 x 8.66 inches (~52 x 26.9 x 22 cm) and it weighs 69 pounds (~31.3 kg) - it is often said that the battery belongs to the BCI Group 4D, but the battery is wide enough to be considered as true BCI Group 8D battery.

According to the manufacturer, the Ampere Time 12V 300Ah lithium battery supports 4000+ charging/discharging cycles and comes with a 10-year limited warranty.

The battery supports up to 4 batteries connected in parallel and/or up to 4 batteries connected in series, enabling the users to create lithium battery packs with the capacity of up to 1200(!) Ah.

Single Ampere Time 12V 300Ah lithium battery is able to provide 200 Amps continuously and 400 Amps for 5 seconds.

Although this is a deep cycle battery, 4 (four) Ampere Time 12V 300Ah lithium batteries connected in parallel can provide 800 Amps continuously and up to 1600 Amps for 4 seconds - enough to crank some serious gas and diesel engines :)

Seriously, these are huge currents, but if You have, for example, an RV, four Ampere Time 12V 300Ah lithium battery can come in very handy as an RV house battery, but it is also highly recommended to have a dedicated starting/cranking battery, for example, Odyssey 31-PC2150 (Amazon link, opens in the new window) or some similar, high-quality battery.

If the application can benefit from ultralight design and a high number of supported charging/discharging cycles, then yes, lithium batteries are worth it.

How long do 12V lithium batteries last?

It depends on use, but there are models that feature warranty periods of 5-10 years and support 3000-5000 charging/discharging cycles down to 80-100% DoD.

What are 12-volt lithium batteries used for?

12-volt lithium batteries are used as trolling motor batteries, as solar batteries, as off-the-grid batteries, as inverter batteries, as RV house batteries, in medical and security systems, etc.

What is the price of a 12-volt lithium-ion battery? How much does it cost to replace a lithium-ion battery?

It all depends on the battery model - there are many low-cost 12V lithium battery models, but like everything in life, there is a reason why they are cheap.

Personally, when looking for a new lithium battery, go for the model that has many good reviews by users that have already tried and tested the battery in real-life situations.

Hardly. Maybe if it is not used, just maintained properly.

But, what is the benefit of just having a stored battery?

Let the batteries, lithium or not, serve You and not vice versa.  


Few Final Words

Lithium batteries are here to stay. They offer many benefits over lead-acid batteries, but the lead-acid batteries are not dead yet.

On a contrary, with the development of lithium batteries, new lead-acid batteries are being developed, too, filling in the gaps left by lithium batteries.

Lead-acid or lithium, these batteries are able to provide strong currents and should be treated properly - whatever You do, safety first!
