What Are the Best Rechargeable Batteries?

Rechargeable batteries are great in the sense that they allow for extended use. These batteries are not just a win in longevitya lot of them are well-known for superior performance too, whether for daily or occasional applications. Usually, they are best used for high-power output devices as well as for outdoor applications like camping.

While they all have their specific functions, some are significantly at an advantage in terms of battery attributes. Here's a quick look at each rechargeable battery type to help you pick out the best one the next time you need to buy some power packs.

Types of Rechargeable Batteries

Nickel Cadmium

These are the oldest type of rechargeable AAA batteries and are not used that much nowadays. Nickel-cadmium batteries are highly toxic and have a high self-discharge rate as well. They pose a lot of risks to user safety which is why they have been mostly replaced by metal-hydride-based batteries.

Nickel Metal-Hydride

This rechargeable battery type has a nominal voltage of 1.2V. They come in the form of newer AAA batteries with a capacity of 6001,300 mAh and have almost a similar composition to a nickel-cadmium battery, except that the cadmium was substituted with a different alloy for safer, more stable performance.


Lithium-ion or li-ion batteries include 18650s, 12V batteries, AAA/AA batteries, and batteries used to power most of our electronic devices. These batteries are probably the most commonly used out of all rechargeable batteries especially prominent brands like the Panasonic Eneloop rechargeable batteries. The only downside for some li-ion batteries is the risk of explosion, so it's best to be extra careful and follow all safety measures before, during, and after using them.

Lead Acid

Lead-acid batteries are usually ideal for the outdoors as camping batteries. Its most popular type is the Absorbent Glass Mat (AGM) battery which is known for its low self-discharge rate, reliability, and affordable price.

Lithium Iron Phosphate

If you're looking for the best 12V rechargeable battery, here is it. The lithium iron phosphate batteries or simply LiFePO4 batteries boast a modern, safer composition that offers superior quality and lifespan. These power packs are versatile too and can be used not just in camping but also as marine batteries and battery backups.

What Makes LiFePO4 Batteries Special?

The heart of LiFePO4 batteries is their built-in battery management system (BMS). It optimises each cell in your battery pack for a stable run time and offers automatic protection against common battery issues including overheating, overcharging, and short circuits.

These rechargeable lithium batteries are usually compatible with solar and have a fast-charging feature too. They're great as lithium RV batteries paired with solar panels for convenient off-grid camping.

Despite being more expensive than most batteries, opting for a LiFePO4 gives you 7 to 10 years of service life plus unrivalled versatility. You're sure to get the most out of your investment instead of having to replace them every few years and since they fare better in extreme conditions, you have a lot more camping options to choose from!
