Lithium Rechargeable & LiFePO4 Replacement Batteries

Why Switch from Lead-Acid to Lithium Rechargeable Batteries?

If you're currently using SLA or AGM batteries, switching to rechargeable lithium-ion (LiFePO4) can be an excellent long-term solution. While the upfront price is higher, their "cost per cycle" comes out to be much lower. A standard lead-acid battery provdies 300-500 cycles (recharges), whereas a LiFePO4 battery provides 2,000 to 5,000 cycles depending on how deeply they get discharged - providing much longer life for the dollars invested.

Key Benefits of LiFePO4 Technology:

• Consistent Voltage: SLA batteries will see a voltage drop as they discharge (commonly called a discharge curve). Lithium maintains a steady power output until they are nearly empty.
• Deep Cycle Performance: You can safely use 80-100% of a lithium battery's full capacity, compared to only 50% of a lead-acid before an SLA battery starts to sputter.
• Built-in BMS: Every battery includes a Battery Management System (BMS) that protects against overcharging, deep discharge, and short-circuiting. Some also include Bluetooth capabilities to monitor your battery status with an app on your phone.
• Weight Savings: Reducing weight by up to 70% improves acceleration and hill-climbing in golf carts and reduces strain on portable battery backup systems.

Frequently Asked Questions

Is a lithium battery rechargeable?

Yes, all the batteries in this category are fully rechargeable. Specifically, we carry LiFePO4 (Lithium Iron Phosphate), which is the safest and most stable form of lithium chemistry available for deep cycle and starting applications.

Can I replace my 12V SLA battery with a 12V lithium battery?

In most cases, yes. Many of our lithium batteries are designed with the same dimensions as standard SLA batteries (like the 12V 7Ah or 12V 12Ah sizes), making them a "drop-in replacement." However, you must ensure your charger is lithium-compatible to reach a full 100% state of charge.

How long do lithium rechargeable batteries last?

Most LiFePO4 batteries last between 5 to 10 years. In terms of usage, you can expect 10 times the longevity of a typical lead-acid battery, often exceeding 3,000 charge/discharge cycles before seeing any significant capacity loss. A particular standout here is Dakota Lithium—they offer an astounding 11-year warranty on their batteries to prove they'll last for years to come.

Do I need a special charger for lithium batteries?

Yes. While some smart AGM chargers can work, we highly recommend using a dedicated lithium-ion battery charger. Lithium batteries require a specific constant current/constant voltage (CC/CV) charging profile to balance the internal cells and maximize life.
