Previously in another article, we briefly discussed the Top 12 Deep Cycle RV Batteries, which are the most important source of power supply at any outdoor activity. However, if you only need a power source for a lantern, a 6-volt battery outperforms normal torch batteries. It’s best to opt for a reliable 6-volt battery that quickly gives a large amount of power.

What Is a 6-volt Lantern Battery?

Torches and lanterns both use 6-volt lantern batteries, which are rectangular and often alkaline in composition. They are made up of numerous cells contained within a single housing, which causes them to be physically larger than ordinary batteries. Their bigger size enables them to provide more power than smaller torch batteries, such as AA, C, and D.

What Are the Uses of Lantern Batteries?

Most of the common questions I got is what are 6-volt lantern batteries used for? Significantly, torches and lanterns are frequently powered by batteries, which have a higher energy capacity and a sealed design that allows them to endure repeated usage. This is especially critical when torches or lanterns are being utilized under difficult or nominal working circumstances. Nominal capacity depends on various factors, including discharge current, discharge temperature, device cutoff voltage, etc.

Lantern Battery Volt Types

The following are the many types of lantern battery Volts:


The terminals of the 4.5-volt lantern battery are made of metal strips. It is mainly employed to provide power to torches.


A three-cell sealed lead-acid battery constructs the 6-volt rechargeable variety. Typical use in construction, work lights are powered by these batteries.


The 7-volt type contains screw terminals and a rectangular base, while the 12-volt type does not. It is common practice to connect a carrying handle between the terminals to improve ease of use in situations where it is critical, such as in the construction industry.


In addition to screw terminals and a rectangular base, the 12-volt version includes a rectangular base as well as screw terminals. When used in conjunction with an adaptor, it can be utilized to power vehicle accessories.

6-volt Lantern Batteries Specifications and Features

Lantern batteries are lead-acid batteries made up of four bigger cells, typically 1.5V D batteries joined together. Manufacturers claim 9-12 Ah capacity for 6-volt carbon-zinc alloy lantern batteries. Astringent Batteries for 6-volt lanterns normally have 12-18 Ah capacities, while certain low-current variants can have up to 26 Ah. Most heavy-duty alkaline batteries have 12 to 15 Ah capacity. 

 A 6-Volt battery contains the following features:

  •  6-Volt Batteries have a larger capacity for energy storage;
  •  It has a thicker plate for sturdiness;
  • They can be used for a longer period;
  • Most 6V batteries are deep cycled to maximize storage and discharge capacity;
  • Ideal for those on a budget;
  • Allow charge and discharge for a longer time.

Types of 6-volt Lantern Batteries

The most common type of 6-volt lantern battery is the non-rechargeable variety; however, rechargeable 6-volt lantern batteries are also available. 

In most cases, non-rechargeable 6-volt zinc-carbon or alkaline lantern batteries with spring connections are utilized in a lantern. But there are three types of 6-volt lantern batteries: spring-top terminals, screw-top terminals and rechargeable 6 V batteries.

Following are the details:

Spring-Top 6-Volt Lantern Batteries

Positive and negative terminals are located in the same corner of the spring-top 6-volt lantern batteries, making them ideal for use in lamps and other lighting applications. MN908 (alkaline), 4R25 (carbon-zinc), 908A (alkaline) et al. are standard labels for these batteries. 

A few brands utilize their own labels, such as [amazon link=”B07RXVJ8JK” title=”Energizer Max 6V Lantern Battery” /]. Spring terminals are more typical for ordinary usage.

Screw-Top 6-Volt Lantern Batteries

Battery dimensions are 109.5 x 66.7 mm for screw-top 6-volt lantern batteries. The positive terminal is located at one of the corners of the battery, and the negative terminal is located in the middle.

There are also a variety of labels for these batteries, including 4LR25X (alkaline), 4R25X (carbon-zinc), and others. Some of the most common labels for these batteries are 915A (alkaline), 915 (carbon-zinc), and 915A (alkaline). Battery terminals with screw tops can be used in applications requiring a more secure connection between the battery and wires.

Rechargeable 6-Volt Lantern Batteries

Chargeable 6-volt lantern batteries are less common than non-rechargeable types and therefore are more expensive. But the only challenge of using the rechargeable battery is using the appropriate charger. Because it’s important to know whether you can use a 12v Charger for a 6v battery or not.

Batteries for rechargeable 6-volt lanterns can be made in a variety of chemistries, including the following:

Lead-acid Chemistry

Lead-acid batteries have three flat cells, each having a nominal voltage of 6 volts and 4-5 AH capacity.

Four NiCd F-Size Batteries

Battery holders explicitly designed for NiCd F-size batteries have nominal voltages of 4.88 and 6.6-7 Ah, respectively, which means they can handle large currents.

Four NiMH F-Size Batteries

Nominal voltage is 4.8 volts, with a capacity of 12-18 Ah, from four NiMH F-size batteries in a unique battery holder.

Our Recommendation of 6-volt Lantern Batteries
