Lg Hg2 Vs Samsung 25r Are People Still Using The Hg2 In 2024 Or Is The 25r Better For Vapes

The LG HG2 and Samsung 25R are two of the most discussed 18650 batteries in the vaping community. While both have long been staples in mechanical mods and high-drain devices, the landscape has evolved. As we move deeper into 2024, questions arise: Is the LG HG2 still relevant? Has the Samsung 25R surpassed it in practicality and safety for modern vaping? This article breaks down their specs, real-world performance, user trends, and longevity to help you make an informed decision.

Battery Basics: Why Cell Choice Matters in Vaping

Selecting the right battery isn’t just about power—it’s about safety, consistency, and device compatibility. Vaping, especially with unregulated (mechanical) mods, places high demands on batteries. A cell must deliver stable current under load, resist overheating, and maintain capacity over time. Poor choices can lead to voltage sag, reduced coil life, or worse—thermal runaway.

The LG HG2 and Samsung 25R were both designed as high-drain lithium-ion cells, but they serve slightly different niches. Understanding their core specifications helps clarify why one might be preferred today over the other.

Key Specifications Compared

Feature	LG HG2	Samsung 25R
Capacity	3000 mAh	2500 mAh
Continuous Discharge Rate	20A	25A
Pulse Discharge (up to 3 sec)	30A	35A
Voltage (Nominal)	3.6V	3.7V
Recommended Max Charging Current	1.5A	2.0A
Introduced	2014	2013
Status in 2024	Discontinued, limited stock	Still widely available

Tip: Always check your mod’s resistance requirements and match them with a battery’s safe discharge limit. For sub-0.2Ω builds, 25A+ continuous discharge is strongly recommended.

Performance in Real-World Vaping Scenarios

The Samsung 25R excels in high-drain applications due to its 25A continuous discharge rating. This makes it ideal for low-resistance coils (0.15Ω–0.3Ω) commonly used in rebuildable atomizers. Users report minimal voltage sag even during extended firing, resulting in consistent flavor and vapor production.

The LG HG2, while offering higher capacity (3000 mAh), maxes out at 20A. This is sufficient for moderate builds (0.3Ω–0.5Ω), but pushes the cell closer to its limits when used in more demanding setups. In mechanical mods without protection circuits, this increases risk if the user misunderstands Ohm’s Law or uses degraded coils.

“Battery safety isn’t just about specs—it’s about how users apply them. The 25R’s headroom gives marginally safer operation in high-power scenarios.” — David Tran, Electrical Engineer & Vape Safety Advocate

Thermal Performance and Longevity

In independent tests conducted by vaping forums like ECF (E-Cigarette Forum), the Samsung 25R consistently runs cooler under sustained load compared to the HG2. This thermal efficiency contributes to longer cycle life and reduced wear. After 200 charge cycles, the 25R retains approximately 88% of its original capacity, whereas the HG2 drops to around 82%, partly due to its older chemistry and design.

Moreover, the 25R features improved internal resistance management, which reduces heat buildup—a critical factor in preventing venting or rupture.

Are People Still Using the LG HG2 in 2024?

Yes—but sparingly. The LG HG2 was officially discontinued several years ago, and genuine units are now rare. What remains in circulation are often old stock, resold cells, or counterfeits. Reputable vendors no longer carry them, and many experienced vapers have phased them out due to availability concerns and advancing alternatives.

A small segment of users still swear by the HG2 for mid-wattage regulated devices or higher-resistance mechanical builds. Its 3000 mAh capacity offers longer runtime than the 25R in less intense setups. However, sourcing authentic HG2s is increasingly difficult, and buying from third-party sellers carries significant risk.

Mini Case Study: Mark’s Transition from HG2 to 25R

Mark, a long-time mechanical mod user from Austin, TX, relied on LG HG2s for his dual-tube setup from 2016 to 2021. He appreciated their balance of capacity and performance for 0.3Ω fused clapton coils. But by 2022, he noticed increasing inconsistency—some cells wouldn’t hold charge past 2,400 mAh, and one showed signs of swelling after six months.

After consulting with a local vape shop technician, he switched to Samsung 25Rs. “The initial runtime felt shorter,” he said, “but the hits are stronger, and my mod doesn’t get nearly as hot. I’ve had the same set for over a year with no degradation.”

Safety and Modern Best Practices

In 2024, battery safety standards have tightened. Regulated mods with built-in protections (short circuit, over-discharge, temperature control) dominate the market. Even so, high-performance rebuildable dripping atomizers (RDAs) and mechanical mods remain popular among enthusiasts.

Using outdated or discontinued cells like the HG2 introduces uncertainty. Without manufacturer support, warranty, or updated testing data, risk increases. Meanwhile, the Samsung 25R benefits from widespread verification, trusted supply chains, and consistent quality control.

• Always use a proper external charger with voltage and current monitoring.
• Inspect batteries monthly for dents, scratches, or insulation damage.
• Never mix brands or ages in a multi-battery device.
• Store spares in protective cases, away from metal objects.

Tip: Label your batteries with purchase dates. Retire any 18650 after 2 years of regular use, regardless of apparent condition.

Checklist: Choosing the Right Battery in 2024

1. Confirm your device’s maximum current draw and match it with a battery’s continuous discharge rating (add a 5A safety buffer).
2. Prioritize availability and authenticity—avoid discontinued or gray-market cells.
3. Use only reputable vendors (e.g., Illumn, Liion Wholesale, IMR Batteries).
4. Verify each cell with a multimeter and battery analyzer upon arrival.
5. Replace batteries every 12–24 months, depending on usage frequency.

FAQ: Common Questions About HG2 vs 25R

Is the LG HG2 better than the Samsung 25R for battery life?

The HG2 has a higher nominal capacity (3000 mAh vs 2500 mAh), so in lower-drain devices, it may last longer per charge. However, in high-power builds, the 25R’s superior current delivery and thermal management often result in more usable energy and consistent output.

Can I still buy genuine LG HG2 batteries in 2024?

Genuine LG HG2s are no longer manufactured, and new-old-stock units are scarce. Most \"HG2s\" sold today are either used, recycled, or counterfeit. Experts strongly advise against purchasing them unless sourced from a verified, trusted inventory with recent batch testing.

Which battery is safer for mechanical mods?

The Samsung 25R is generally considered safer due to its higher discharge rating, better thermal response, and ongoing production with quality oversight. Its 25A rating provides a safer margin for builds under 0.3Ω, reducing the chance of exceeding safe amp limits.

Conclusion: Making the Smart Choice in 2024

The LG HG2 was once a top-tier choice, respected for its balance of capacity and performance. But in 2024, the Samsung 25R stands as the more reliable, accessible, and safer option for vapers—especially those using high-drain devices. While nostalgia and anecdotal success stories keep the HG2 alive in some circles, its discontinuation and scarcity make it a risky pick.

Technology moves forward, and so should our safety practices. The 25R offers peace of mind through proven performance, wide availability, and strong community validation. If you're still relying on aging HG2s, consider upgrading to fresh, certified 25Rs—or explore newer options like the Samsung 30Q or Molicel P28A for even better efficiency.
