Can You Replace One Battery on a Golf Cart? A Practical Guide — Featuring Lexsong

Golf carts depend on battery packs to deliver consistent power, driving range, and performance. Over time, batteries wear out, leading many owners to ask:
Can you replace just one battery on a golf cart instead of the entire pack?

The short answer is: Yes, but it’s usually not recommended—especially for long-term reliability.

How Golf Cart Battery Packs Work

Most electric golf carts use multiple batteries connected in series to reach system voltages such as 36V, 48V, or 72V. Common setups include:

• 6V batteries

• 8V batteries

• 12V batteries

These batteries work as a complete system, meaning overall performance depends on balanced battery age, capacity, and health.

Can You Replace Just One Battery?

While it’s technically possible to replace a single failed battery, doing so can cause performance imbalance if the remaining batteries are older or degraded.

Potential risks include:

• Uneven charging and discharging

• Reduced total battery lifespan

• Shorter driving range

• Faster wear on the new battery

• Unstable power output

A single new battery often ends up working harder than older ones, which shortens its life.

When Is Single-Battery Replacement Acceptable?

Replacing only one battery may be reasonable if:

• The battery pack is nearly new

• The other batteries are in similar condition

• It’s used as a short-term or emergency solution

Regular voltage and capacity testing is recommended in these cases.

Lexsong Recommendation: Replace the Full Battery Set

At Lexsong, we recommend replacing the entire battery pack whenever possible to ensure:

• Balanced power delivery

• Longer battery lifespan

• More stable performance

• Better driving range and efficiency

• Lower long-term maintenance costs

This is especially important for commercial fleets, golf courses, resorts, factories, and high-usage electric golf carts.

Lead-Acid vs Lithium: What Lexsong Advises

• Lead-acid systems are highly sensitive to imbalance, so full-pack replacement is strongly recommended.

• Lithium battery systems (with BMS) offer better cell management, but pack-level consistency is still key for best performance.

Lexsong golf carts are designed with high-quality lead-acid and lithium battery options, optimized for durability, safety, and long-term value.

Conclusion

While replacing one battery on a golf cart is possible, it is usually not the best long-term solution. For optimal performance, reliability, and battery life, Lexsong recommends replacing the full battery set to maintain balanced power and reduce future issues.

Choosing a Lexsong electric golf cart means benefiting from professional battery system design, global export standards, and dependable after-sales support.
