FAQ

Generally, what are Lithium-Ion Batteries?
A. Lithium-ion batteries are rechargeable batteries in which lithium ions move from the anode to the cathode during discharging and back when charging. They are popular batteries for use in consumer electronics because they provide high energy density, possess no memory effect and have a slow loss of charge when not in use. These batteries come in a wide variety of shapes and sizes. Compared to lead-acid batteries, Lithium-ion batteries are lighter and provide a higher open circuit voltage, which allows for power transfer at lower currents. These batteries have the following characteristics:

Features of ionic Lithium-ion Deep Cycle Batteries:

Light weight, up to 80% less than a conventional, comparable energy storage lead-acid battery.
Lasts 300-400% longer than lead-acid.
Lower shelf discharge rate (2% vs. 5-8% /month).
Drop-in replacement for your OEM battery.
Expected 8-10 years of battery life.
No explosive gasses during charging, no acid spills.
Environmentally friendly, no lead or heavy metals.
Safe to operate!
The term “Lithium-ion” battery is a general term. There are many different chemistries for Lithium-Ion batteries including LiCoO2 (cylindrical cell), LiPo, and LiFePO4 (cylindrical/prismatic cell). Ionic mostly focuses on designing, manufacturing and marketing LiFePO4 batteries for its starter and deep cycle batteries.

What are LiFePO4 (Lithium Iron Phosphate) Batteries?
A. Lithium Iron Phosphate (LiFePO4) batteries provide several advantages over traditional Lithium-ion batteries based on LiCoO2 chemistry. LiFePO4 batteries provide much higher specific capacity, superior thermal and chemical stability, enhance safety, improve cost performance, enhanced charge and discharge rates, enhanced cycle life and come in a compact, lightweight package. LiFePO4 batteries an offer a cycle life of over 2,000 charge cycles!

Why should I get a ionic’s lithium-ion “Deep Cycle” energy storage battery?
A. Lithium-ion batteries provide multiple advantages over standard lead-acid batteries for energy storage use that we’ll outline below:

Substantially Lighter – Lithium-ion batteries are just a fraction of the weight of the original lead-acid battery.
More Powerful – Lithium-ion batteries operate at a higher voltage than standard lead-acid batteries, giving you faster engine speed for longer durations. Lead-acid batteries drop to just 12.5V when only 20% of the battery capacity is used, but lithium-ion batteries provide over 12.8V even when only 20% of the battery capacity is left.
Low Self-Discharge Rate– Lead-acid batteries lose 4%-25% of their charge every month depending on the quality of the plates and separators used. If you leave a vehicle unattended for a month, the lead-acid battery might lose too much power and the vehicle might not start. On the other hand, our lithium battery chemistry loses less than 3% of charge per month; you can go for several months without having to worry.
Environmental Friendly– Ionic batteries contain no toxic substances. There is no poisonous lead or corrosive sulfuric acid and as a result, no possible way for an explosive gassing event that is common with lead-acid batteries. In addition, there is no need to maintain acid levels or worry about venting like traditional lead-acid batteries do. The only maintenance that ionic batteries require is ensuring that the battery never drains beyond 80% to ensure optimal life.
Long Lasting– Cheap lead-acid batteries usually only last 1 to 2 years while gel and AGM lead-acid batteries last 3-5 years with proper maintenance. However, ionic’s lithium-ion batteries can provide 8-10 years of use, easily exceeding the life of any lead-acid battery. Battery life depends purely on proper operation and maintenance, so use common-sense and ensure the battery does not drain beyond 80% discharge. If you are replacing a lead-acid battery in two years or less due to deep cycling damage, you will save money in the long run moving to a ionic lithium-ion
Fast Recharging – ionic’s lithium-ion batteries can accept charge current at up to 5 times faster than a lead-acid battery. What’s more, the charge efficiency is about 75% for lead-acid in contrast to 97% for ionic’s lithium-ion battery. That means less energy is needed to charge and causes less strain on your alternator.

What advantages does ionic “Deep Cycle Batteries” have over other batteries?
A. ionic utilizes the latest advancements in lithium-ion battery technology along with custom features to provide you with the best battery for your vehicle:

Internal Cell Balancing Circuit – ionic batteries have a micro-processor controlled internal cell balancing board in each of its batteries designed to maximize the performance of each cell in the batteries.
Battery Management System (BMS) – ionic lithium-ion smart batteries contain a solid state switch that controls temperature volatility. This switch prevents overcharging and discharging, improving the overall lifespan performance and safety of the batteries.
Quality Engineering – ionic’s innovation laboratory prides itself on the design and construction of its batteries utilizing the highest quality components in all phases of design and construction. The ionic built-in intelligent components guarantee the safety and quality of each ionic product.
Prismatic Cells – Cylindrical cells only come in certain sizes which limits the possible shapes and sizes of the starter battery case designs. As such, batteries fit for many vehicles may be poor, or impossible as they are too wide or too tall and create internal hot spots. Ionic prismatic cells on the other hand, are rectangular packages which can be freely designed and sized according to the size requirements of the battery case. As such, ionic offers perfect drop-in fit in most vehicles along with having better thermal management properties.

How does ionic’s “Deep Cycle” capacity (Ah) rating compare to lead-acid Ah ratings?
A. Ionic’s “Deep Cycle” batteries have true lithium capacity rating at 1C discharge rate meaning a 12Ah “Deep Cycle” lithium-ion battery will be able to provide 12A for 1 hour. On the other hand, most lead-acid batteries have a 20hr or 25hr rating printed for its Ah capacity meaning the same 12Ah lead-acid battery discharging in 1 hour would typically only provide 6Ah of useable energy. Going below 50% DOD will damage a lead-acid battery, even if they claim to be a deep discharge battery. Thus a 12Ah lithium battery would perform closer to a 48Ah lead-acid battery rating for higher discharge currents and life performance.
Ionic’s lithium-ion batteries have 1/3 the internal resistance of a similar capacity lead-acid battery and they can be safely discharged to 90% DOD. Lead-acid internal resistance rises as they are discharged; the actual capacity which can be used may be as little as 20% of the mfg. rating. Discharging in excess will damage the lead-acid battery. Ionic’s lithium-ion batteries hold a higher voltage during discharge.

IMPORTANT: PRE-USE GUIDELINES

DO: Perform a Pre-Installation Check!

Ensure a thorough examination before installation:

Inspect Each Cell**: Visually check for any damage, swelling, leaks, or missing accessories. Do not use a cell if the casing is pierced, leaking, cracked, or otherwise visibly damaged.
Clean the Terminals: Ensure bus bars, wire terminal lugs, and terminals are clean and free from corrosion or debris. This helps reduce resistance between the DC terminal and cable connection.
Test Voltage and Capacity: Use a multimeter to check each cell’s voltage and internal resistance, and a battery analyzer or specialized tester to confirm the capacity.
Top Balance Before Use: Charge all cells to full voltage before assembling them. We recommend using chargers specifically designed for LiFePO4 cells.

DONT:

Do Not Discharge Immediately After Delivery. Allow battery to settle before use.
Do Not Mix Cells from Different Series: Even if they are the same type and capacity, avoid mixing cells from different manufacturing series or batches. Always use cells from the same batch.
Avoid Loose Terminal Connections: Ensure all terminals are securely fastened to prevent performance issues.

Kindly Reminders: • Production time: 10 to 15 days for samples; 25 to 30 days for bulk orders. • Transportation methods: By couriers, air, truck, sea. • Payment terms: TT/PayPal/Assurance order.
