Buying Guide for Newbies

Now that you have gone through the reviews, choosing one might be a bit easy for you. However, if you want things to be much easier, you should keep some of the crucial factors in your mind. Wondering what factors are we actually referring to here? They are as stated:

Reserve Capacity

The first thing that should be in your consideration is the reserve capacity. This is not going to be the same for each of the models. Some will have a larger capacity, while some will have an average capacity. Among all of them, our recommendation would be to get the ones with a large capacity.

Usually, the large capacity ones will be capable of offering power for a long amount of time. Some can offer up to 120+ hours. However, if you do not need that amount of runtime, opt for the ones that can offer at least 100 hours of run time.


One of the important factors of these is efficiency. The higher the efficiency level, the better the performer the battery is going to be. Also, the efficient ones would be able to offer consistent voltage throughout the discharge cycle. So, we would highly recommend opting for the ones with a good level of efficiency.

Charging Time

Another quite important thing is the charging time. Usually, the ones with higher capacity would take a long time to charge up. However, if you get the units that have a proper charging circuit, it would take considerably less amount of time to recharge the cells.

Charging/Discharging Rate

The rate of charging/discharging is quite important as well. This will basically indicate the overall service life of the cells. And the higher the rate, the higher the lifespan of the cells will be. Also, the ones with higher charging/discharging rates can also offer optimal performance for a long amount of time.


Most of the brands are going to skimp on the housing. However, this is an important factor that you should consider before making a purchase decision. In this case, our recommendation would be to opt for the ones with sturdy housing. Those will be highly resistant to vibrations.

And the ones that are highly resistant to vibrations would be able to withstand rough terrains pretty easily. Also, they would last for a long amount of time without showing any signs of performance issues.


The last thing that should be in your consideration is the design. Ensure that the unit is spillproof, or else the installation process will be a bit tough. The spillproof ones are usually capable of being installed in all of the positions. And they are highly capable of eliminating the chances of leakage occurring.
