Lithium batteries are the best option for the mountain

There is no doubt that in the 21st-century technology has advanced in the field of energy and more specifically in the manufacture of increasingly efficient batteries. Today, we can find high-tech batteries that are capable of being charged with sunlight, even if the sun is covered by clouds. Also many o,f these rechargeable batteries are hermetic to be able to carry them in our adventures of hiking, climbing, snowshoeing through the snow or any sport that occurs to us by the mountain.

Of all of them we can highlight the RokPak battery, with it you can load any type of device that you carry with you.

It has a sophisticated design: in the shape of a briefcase, inside it houses a hole (apart from the battery) to protect your devices while safely loading resisting shock and water thanks to your impermeability. And on the outside, it has solar panels to take advantage of all the solar energy and charge the battery. It allows you to be carrying your phone inside safely.

It is built to withstand the harshest conditions. It is water resistant certified with the IP67 rating and has passed the Military Standard 810G which is a fall impact test.

Your solar panel absorbs the sun’s rays and channels them to your device with its USB charging ports. Because it has standard USB ports, you can load any electronic device that has the same port, including smartphones, tablets, cameras, GPS systems and anything else you can think of. Although naturally, not all will fit inside.

Its strength is its gigantic 10,000mAh lithium-ion battery that should be large enough to charge most smartphones four times, which is impressive. It works in temperatures of up to 80 degrees, and temperatures as cold as minus 20 degrees.

Regardless of the external battery, you buy, if you are going to take a long mountain tour and you know you will not have plugs where to recharge it, you may purchase a solar panel charger is a very successful option.

What batteries to use at any time

Batteries provide power for many products in your home, from your children’s toys to remote-controlled cars. There are two types of batteries in the market: rechargeable and disposable.

Rechargeable batteries are more expensive than disposable batteries, costs a minimum of 15 euros a pack of eight AA batteries. Behind the rechargeable batteries there are different types of technology, for example, the older batteries are nickel-cadmium (NiCd), while experts say that the most effective are nickel-metal-hydride (NiMH).

Despite its initial cost, without a doubt, rechargeable batteries are an excellent long-term value. That’s because batteries of this variety can be recharged and used repeatedly from 100 to 1,500 times, according to energy experts. If you pay 20 euros for a pack of four AA batteries and a charger, and you use them 500 times before they wear out, their cost per use (including the electricity used to charge) is about 5 cents. On the contrary, four alkaline disposable battery packs would cost you between 2 euros and 4 euros.

In addition to being more profitable, rechargeable batteries are a greener option. The choice to buy rechargeable batteries instead of 500 alkaline batteries reduces the amount of waste by 500 times. It is also easy to recycle rechargeable batteries at the end of their lives leaving them in green dots. Disposable batteries, on the contrary, in most cases. It should also be remembered that although we can recycle any type of batteries, they are never 100% recycled, therefore, the more we reduce their use buying rechargeable batteries, the more significant contribution we will make to the environment.

Why buy disposable batteries

In the past, rechargeable batteries had some significant drawbacks compared to disposables. 1st, they tended to lose their charge over time, so stored cells often had to be recharged before use. This made them less suitable for emergencies. However, modern low-discharge rechargeable (LSD) batteries, such as the Panasonic Eneloop, have largely eliminated this problem. These batteries conserve about 75 percent of their charge after one to three years of storage.

Advantages of disposable batteries

However, disposable batteries have some benefits of their own. While new technologies have significantly improved the life of rechargeable batteries, they still deteriorate compared to the life of disposables, which can last 10 to 15 years, depending on the type. Disposables also store more energy than rechargeable ones, which means that rechargeable batteries will continue to power any device compared to rechargeable batteries that have probably had to be charged several times.

The cheapest and most available batteries are alkaline batteries. Manufactured by well-known brands such as Duracell, Energizer, and Rayovac, these usually cost around 5 euros per pack of eight AA batteries, which is the most common size. However, alkaline batteries work best with devices with low amperages like a remote control car or a flashlight.

Disadvantages of disposable batteries

Disposable batteries pollute more than rechargeable batteries, needing more of these for the same purpose and to be of single use. Every time you run out of alkaline batteries you have to buy new ones and throw out the old ones.

They are not suitable for devices with high energy demand since they will not be able to make them work.

Rechargeable batteries are a great option. You can use them again and again so you’ll save money over time. There are many brands of rechargeable batteries that offer different features. You should not be fooled by the marketing that some companies develop. There are cheap rechargeable batteries that fulfill their function amply, without you having to spend a lot of money.

Buy the best batteries

To find the best batteries, you have to take into account two main factors: performance and autonomy. Production includes the capacity of the batteries, the amount of time the stored batteries last without being spent, and, for rechargeable batteries, the time it takes to charge. Autonomy, for alkaline batteries and lithium batteries, is a matter of how much energy they can transmit before they stop working. For rechargeable batteries, the autonomy also includes the useful life or the number of times that can be recharged. Information on performance and autonomy can be found in tests conducted by professionals and online publications. user reviews help us find information about specific problems with batteries,

Advantages of lithium batteries

Lithium batteries, like alkaline batteries, are disposable. However, they have more energy than alkaline batteries and can withstand higher currents. In a test conducted by experts, lithium batteries last approximately 50 percent longer than chemical batteries with a low current draw of 200 milliamps (mA), which is roughly the amount used for a child’s toy or flashlight. At a higher current consumption of 1,000 mA, comparable to a digital camera, the difference was even more significant: lithium batteries lasted almost three times longer than alkaline batteries.

Lithium batteries weigh less than alkaline batteries and work best at shallow temperatures, something to consider when we go camping, hiking, mountain climbing or hiking. Also, they have a longer storage life. While alkaline batteries last for 10 to 15 years, stored, lithium batteries can last 10 to 15 years, making them useful for emergencies. That’s because they do not self-discharge or consume their energy as fast as alkaline batteries.

A lithium battery will last approximately 50 percent longer, but it will cost twice as much. The exemption is devices with very low power consumption, such as smoke detectors. In this case, lithium batteries have an advantage due to their lower self-discharge rate. Many users say that they have been able to maintain smoke alarms for ten years or more, with a single lithium battery. And for high amperage devices, lithium batteries not only provide long life, and save you having to go with extra batteries wherever you go.

Disadvantages of lithium batteries

The difficulty of lithium batteries is their price, around 13 euros for a pack of eight AA batteries. This means that for low-power devices, such as the television remote control, alkaline batteries are more cost-effective.

The best disposable batteries

While rechargeable batteries are the best choice for most everyday uses, alkaline batteries are still useful for emergency use. But is there any difference between the different manufacturers? There is a lot of contradictory information on this point. Many energy experts argue that “the capacity is quite similar to one alkaline manufacturer to another.” More recently, an alkaline battery study conducted at the Worcester Polytechnic Institute ensured that brand-name alkaline batteries were almost identical to generic brands. Therefore when buying alkaline batteries, we must pay more attention to the price and leave aside those ads from the most expensive companies that ensure that their batteries last much longer.

Comparison between cheap and expensive batteries

However, the most recent studies we have seen of alkaline batteries contradict these findings. They found slight but significant differences in the performance of chemical batteries from different manufacturers. Also, users on and other sites that are consulted are much happier with some brands of batteries than with others.

Surprisingly, the two leading brands of batteries, Duracell and Energizer, are not the winners in most of these tests and studies. Instead, essential Rayovac alkaline batteries (€ 18 for 60 AA batteries), which cost around 30 cents each when bought in large quantities, are the big winners. For example, both the Duracell Coppertop (€ 6 for 8 AA batteries) and Energizer MAX (€ 11 for 16 AA batteries) spend faster on a flashlight than the Rayovac alkaline batteries. Rayovac batteries, therefore, work exactly like Duracell and Energizer and yet they are quite cheaper, so they are a good purchase.

In addition, users are more satisfied with Rayovac batteries than with other leading brands. The ratings are positive, and they prefer Energizer or Duracell. That, yes, some valuations assure that the Rayovac alkaline batteries are spent quickly in devices of high energy demand, but that is to be expected with any type of alkaline batteries, and these complaints are not so numerous as to worry. On, the 60-AA battery pack gets a 4.5-star rating based on nearly 240 ratings, and other battery sizes and sizes have a similar or better rating.

Performance of Duracell Coppertop batteries

Duracell Coppertop batteries are also good, but not so much according to the reviews. In a professional test, these batteries are among the best, lasting longer than most alkaline batteries, both in a flashlight and in a children’s toy. However, it places them in the center of the pack. They do it very well in conditions where not much energy is required, but, once again, their performance goes down with high energy demands. This, combined with its relatively high price, leads a part of consumers to opt for other brands when buying.

Duracell Coppertop battery ratings are also a mix. At, where we find more than 4,000 reviews for these batteries, most users are satisfied with them. Reviews usually say that batteries last a long time. However, the ratings found on the manufacturer’s website seem to contradict this point. Many users who claim to be loyal customers of Duracell complain that the new generation of Duracell batteries is very prone to wear without use.

Performance of Energizer MAX batteries

As for Energizer MAX batteries, they are still trendy among users. In more than 1,750 reviews on, about 90 percent of homeowners recommend batteries for their long life. However, some customers, as in the case of the Duracell, have complaints about their excellent download. However, his performance in professional tests is not impressive. A study put them somewhat higher than Duracell for uses where there is high energy demand, but in most tests, their performance is identical or slightly worse.

In general, branded batteries known as Duracell, Energizer, and Rayovac are better in terms of energy efficiency compared to cheaper batteries. Another performance to surprise in the comparison tests is the alkaline batteries of IKEA (3 euros for 10 AA). For uses of high energy demand and low consumption is the clear winner, offering more power than its opponents at a very low price. However, since the IKEA website does not receive consumer feedback, we have not been able to find many user opinions to support this result. If you have the opportunity to buy them, they are undoubtedly a perfect option.

Performance of Energizer Ultimate Lithium batteries: the best choice

There may be some uncertainty about whether any alkaline battery is better than any other, but there is no doubt about the variation in performance between alkaline batteries and lithium batteries. In professional tests, lithium batteries consistently outperform chemical cells by a wide margin, especially in high drain devices. In addition, lithium batteries lose charge at a much lower speed than alkaline batteries. This means that they last longer in storage and in devices that draw minimal current, such as smoke detectors.

In the United States, Energizer is the leading manufacturer of lithium batteries and the only brand backed by professional studios. Energizer sells lithium batteries under two brands: Energizer Ultimate Lithium (€ 14 for 8 AA batteries) and Energizer Advanced Lithium (€ 15 for 8 AA batteries). Energizer claims that its Advanced Lithium batteries last up to six times longer than its alkaline batteries in a digital camera, and Ultimate Lithium batteries can last longer (although it does not say how much longer). Ultimate Lithium batteries also have a longer lifespan: up to 20 years of storage, compared to 12 years of Advanced Lithium. Both battery models come in AA and AA battery sizes, as well as the 9-volt size used in most smoke detectors.

Energizer Ultimate Lithium batteries triumph over the competition in disposable battery tests. They last longer than any alkaline battery in both high consumption and low consumption devices, although their advantage is more significant with high use. It also outperforms its small sister the Advanced Lithium in the comparison test. The Ultimate Lithium has excellent ratings of users on, in more than 2,400 reviews, the owners give 4.6 stars out of 5, saying they are durable, light and ideal for use in cameras. They also highlight its long life and its ability to operate at low temperatures.

The Energizer Advanced Lithium batteries, on the other hand, get about 4.4 stars out of a total of 900 users. Although consumers praise its long lifespan, it is not as long as in the Ultimate Lithium. Since there is little difference in price between the two models, undoubtedly the best option is Energizer Ultimate Lithium batteries, unless you get an offer on Energizer Advanced Lithium batteries.
