Direct Answer: In commercial and industrial applications, lithium batteries deliver a 40% lower Total Cost of Ownership (TCO) compared to Lead-Acid / AGM: lithium supports 100% usable Depth of Discharge without voltage sag (vs. only 50% usable DoD for lead-acid), achieves 3,000–5,000 cycles (vs. 400–600 cycles for AGM), requires zero distilled water maintenance, and supports rapid opportunity charging in under 2 hours.

batteries. A lightweight option which offers charging efficiency and between 3000-5000 life

cycles makes LiFePO4 the optimal choice for a better battery. To ensure the utmost safety and

minimal impact, our chemistry utilizes only environmentally acceptable materials and has

zero emissions with no venting needed.

Showing high performance in both extreme heat and cold, Lithium is about 2.5x more efficient at

low temperatures and operates safely up to 149*F. Furthermore, versatile mounting allows for

your battery to be installed in any direction with the same consistent energy flow throughout the

duration of use. Despite higher upfront costs of LiFePO4, the savings are clear when considering

the true lifetime value.

Lithium FAQs:

Switching from Lead Acid/AGM to LiFePO4 (Lithium-ion Phosphate)

1. What can I use a Lithium Ion GEB Battery for?

You can use a lithium battery for any application that would normally use a single or multiple Lead

Acid, GEL or AGM batteries. GEB batteries are commonly used for Marine, RV, Solar, Industrial,

Performance, Golf Carts, UV, Mobility, UPS, and custom applications

2. Is to LiFePO4 more dangerous than lead acid/AGM?

No, it’s safer than lead acid/AGM. Plus, a GEB Lithium Battery™ has built in protection circuits.

This prevents a short circuit and has under/over voltage protection. Lead/AGM do not, and

flooded lead acid contains sulfuric acid that can spill and harm you, the environment and your

equipment. Lithium batteries are sealed and have no liquids and give off no gasses.

3. What do I need to change in my electrical system to run to LiFePO4 batteries?

Short answer is nothing! Our batteries are designed to be used exactly how lead acid batteries are

used. Common sources:

• Alternator: Most alternators will sufficiently charge GEB lithium ion technology.
• Inverter: Set or program the charging voltage to 14.4V – 14.6V to get the best charge.
• Standard charger: A standard battery charger WILL charge GEB Batteries™ thanks to its advanced BMS.

What if I have a total loss (non-charging system)?

We can recommend some different lithium specific chargers for you but many of our customers use

their current external chargers with our batteries and they work great!

What about wet/damp locations?

GEB lithium batteries are sealed but are not waterproof to locations that might get wet or damp.

It is highly recommended to place all lithium ion batteries in a dry lock box to prevent any water

damage. These batteries are barely water resistant, however taking these extra precautions will

increase the longevity of the battery.

Where/How can I mount it?

The batteries can be mounted in any direction, even upside down. Since there is no liquid in them

and they are solid the battery will work however you mount them.

How do they deal with heat/cold?

Lithium batteries have a larger working temperature than lead acid/AGM. They somewhat effected

by extreme heat (over 150F) and cold (below -20F). However, If it’s cold, simply turn on some

accessories and the battery will self-warm! If it is hot, just make sure air can flow around the battery.

8. What about these melting lithium cell phone & laptop batteries I saw on the news?

There have been very few of these in relation to how many cell phones laptops there are in the world.

Issues have been with the “pouch” style prismatic cell design (limited safety features to make it more

compact for electronics). Our batteries use different chemistry (LiFePO4), have safer cell design

(steel encased cylindrical cells), and have an advanced BMS system for extra protection.

How do I know what size lithium battery I need?

It’s more about what your priorities are. Our lithium has about twice the useable capacity as a lead acid

and AGM batteries. So, if your goal is to get more usable battery time (Amps) then you should upgrade

to a battery with the same Amps (or more). I.e. if you replace a 100amp battery with a 100amp GEB Battery™,

you will get about double the usable amps, with about half the weight. If your goal is to have a smaller battery,

much less weight, or less expensive. Then you can replace the 100amp battery with a GEB 50amp battery.

You will get about the same usable amps (time), it would cost less, and it’s about ¼ the weight.  Refer to the

spec sheet for dimensions or call us with further questions or custom needs.

What is the life expectancy of the battery?

A GEB Battery™ can be used for 3000-5000 life cycles. Depending on usage this can be 10 years or more.

Lead acid and AGM get roughly 300-500 life cycles before their capacity is reduced substantially. Therefore,

even though there is more upfront cost with a GEB Battery, the upgrade saves you allot of money over time.

• What is the primary difference between LiPo and LiFePO4 batteries?
  LiPo batteries offer superior gravimetric energy density (up to 250+ Wh/kg) and higher instantaneous discharge rates (up to 100C+), making them ideal for weight-sensitive applications like UAVs. LiFePO4 delivers significantly longer cycle life (2000-4000 cycles) and exceptional thermal safety for energy storage and heavy machinery.
• Which chemistry is safer under extreme operational temperatures?
  LiFePO4 features a thermal runaway threshold above 270°C, making it intrinsically safer under high thermal and mechanical stress compared to standard cobalt-based LiPo chemistries.
• What factory testing standards does GEB apply to custom battery packs?
  Every GEB battery pack undergoes capacity verification, internal resistance (IR) matching (±1.5mΩ tolerance), automated spot-weld pull testing (≥5kgf), and compliance testing under UN 38.3, IEC 62133, and CE regulations.

Frequently Asked Questions: Lithium vs Lead-Acid TCO & Performance

What is the real-world cycle life difference between lithium and lead-acid batteries?

Quality LiFePO4 batteries deliver 3,000 to 5,000 full discharge cycles at 80% DoD, compared to standard lead-acid batteries which typically last only 300 to 500 cycles before failing.

How does opportunity charging benefit commercial equipment operations?

Lithium batteries accept high-current fast charging without memory effect or acid stratification, enabling opportunity charging during 15-minute worker breaks for 24/7 continuous equipment uptime.

What total cost of ownership (TCO) savings can industrial facilities expect?

Due to 4x longer lifespan, zero maintenance costs, 95% round-trip efficiency, and eliminated battery replacement downtime, lithium systems typically lower 5-year operational TCO by 40% to 60%.
