Another Choice May Suit
Mighty Max ML4-6 SLA 6V 4.5Ah Coleman Battery is the better fit when your lantern specifically uses sealed lead-acid chemistry.
Six rechargeable cells make this set more versatile than a single replacement, especially across emergency lighting, backup equipment, or compatible ride-on toys. Absorbent Glass Mat, or AGM, technology holds the electrolyte around internal plates, which supports spill-resistant operation and removes routine electrolyte maintenance.
The valve-regulated enclosure and low self-discharge rate make prolonged storage more practical than an unflooded lead-acid design. For most homes, the main limitation is confirming that every device accepts rechargeable 6V batteries and that your charger supplies the correct connection.
Bright Spots
- Six batteries support rotation across several compatible devices.
- AGM construction provides maintenance-free, spill-resistant operation.
- Calcium-tin alloy grids support power density and service life.
- Low self-discharge helps preserve readiness during extended storage.
- Shock and vibration resistance suits mobile equipment and ride-on toys.
Points To Keep In Mind
- Rechargeable batteries may not suit every device designed around disposable cells.
- Charging leads or a compatible charger are not established by the supplied information.

Reach For A Different Pick When
Mighty Max ML4-6LI 6V 4.5Ah Lithium Dorcy Battery 4-Pack better serves a compatible Dorcy user who prefers rechargeable lithium power.
The EXP645 serves a broader rechargeable range than its lantern-only title suggests, covering compatible ride-on toys, emergency lights, and exit signs. Two cells provide a useful replacement set for equipment that uses matched batteries, particularly during rotating use.
Its sealed lead-acid AGM construction is designed for maintenance-free operation, and the F1 terminals simplify connector planning. The catch is chemistry: a rechargeable SLA cell should not be placed into a device intended only for alkaline power, even when the voltage matches.
Useful Highlights
- The two-pack supports matched replacement in compatible two-cell devices.
- AGM technology immobilizes the electrolyte for spill-resistant operation.
- A non-conductive ABS case helps resist impact and everyday handling.
- The 20-hour rating corresponds to the stated 4.5Ah capacity.
Honest Caveats
- Not suitable for a device designed exclusively around disposable alkaline cells.
- Lead-acid chemistry weighs more than a similarly rated lithium option.
- A compatible charger and correct terminal polarity remain necessary.
- Keep terminals clean and store the cells in a cool, dry location.

Frequent-use households with compatible ride-on toys or emergency fixtures benefit from the rechargeable two-cell format.
The Right Fit
Energizer EN4.5-6 6V 4.5Ah AGM Rechargeable Battery 6-Pack is a stronger fit for maintaining a larger fleet of compatible devices.
What Matters Before You Replace the Battery
Start with the device label rather than the number printed on the battery carton. Voltage tells you only part of the story; chemistry, physical dimensions, terminal style, and the number of cells determine whether a replacement is appropriate. A lantern designed for disposable alkaline cells should not automatically receive a rechargeable lead-acid battery.
Next, compare the model references. UB645, ELB0604, ML4-6, and EXP645 point to different device applications and should be matched against the original compartment or documentation. This prevents a purchase based solely on a shared 6V rating.
Consider charging access as well. Rechargeable lithium, SLA, and AGM batteries need a compatible charger, while alkaline cells are designed for replacement after discharge. Owners of emergency equipment should also establish a realistic checking schedule, since age and storage conditions affect readiness even when a battery is not being used.
Weight and capacity deserve a final look. Lithium can reduce carried weight in portable lighting, while sealed lead-acid may fit established rechargeable compartments more directly. The stated 4.5Ah capacity gives you a common capacity class across several choices, but the physical design still controls compatibility.
Two Details That Change the Decision
Mistakes Worth Dodging
Matching only voltage can lead to charging problems, incorrect connector fit, or an unsafe mix of rechargeable and disposable cells. Check the original model number, terminal polarity, battery quantity, and charging instructions before ordering.
What Separates Premium From Basic
Lithium options may offer lower weight and a high stated cycle life, while alkaline cells provide the simplest disposable setup. The higher-cost rechargeable choice makes more sense for frequent use or multiple compatible devices, not for occasional cabinet storage.
Frequently Asked Questions
Can a 6V rechargeable battery replace a 6V alkaline battery?
Only after confirming that the device and charger support rechargeable chemistry. Matching voltage alone does not guarantee compatibility.
Which battery fits a Coleman 5348 lantern?
Mighty Max ML4-6 SLA 6V 4.5Ah Coleman Battery is explicitly positioned as a replacement for that model, subject to matching dimensions, terminals, and charging requirements.
Are lithium and lead-acid 6V batteries interchangeable?
They may share a voltage rating while using different charging profiles and terminal arrangements. Use the device documentation and model references before substituting one for the other.
What do F1 terminals mean?
F1 identifies a small blade-style connector. You still need to compare the blade width, position, and polarity with the original battery.
How should spare lantern batteries be stored?
Keep them in a cool, dry location away from moisture and direct heat. Rechargeable cells benefit from periodic checking, while disposable alkaline cells should be replaced when signs of leakage or deterioration appear.
Final Thoughts
The right 6V lantern battery depends less on capacity than on an exact chemistry, connector, and model match. Mighty Max covers Dorcy and Coleman applications, Energizer and ExpertPower support multi-device rechargeable setups, and Duracell handles straightforward disposable use. Verify the original label, follow the device’s charging guidance, and keep a tested spare close to the equipment that depends on it.
