How to choose the right battery for 125cm3 motorcycles?

In order to correctly choose your battery, we invite you to measure the length, width and height of the model installed on your 125. You can of course count a margin of a few centimeters (example: select 110mm if your model is 112mm). We offer 3 types of batteries: maintenance-free gel, lithium and acid (more information on batteries).

The essentials when choosing a new battery

The battery is a major safety organ, so do not neglect it. You will find here many types of batteries for your scooter or your bike as par example the gel battery (maintenance free), the acid battery (without maintenance, in accordance with the new legislation) or the new ones lithium batteries. You will also find on our site testers for the proper maintenance of your battery. We provide you with this document to help you find the ideal battery for your machine. Take the measurements of your old model to find your new part quickly!

As a first step, it is important to remember that each battery is sized epar the vehicle manufacturer depending on the engine and its electricity consumption. It is essential to take this into account when replacing your battery and to respect certain constraints: you must choose a battery with the equivalent amperage and the equivalent dimensions of your original battery.

The different battery technologies

Lithium batteries

Appeared recently for the general public, lithium batteries are very successful although they are much more expensive than standard batteries. We are going to decipher the various advantages and disadvantages of lithium batteries. Let us remind you that the purpose of a battery is to produce the electrical energy necessary for starting. Recent motorcycles have a growing need for energy and lithium fully corresponds to this development. It will indeed make it possible to generate a large quantity of energy. In addition, these batteries are much lighter (three times lighter than a lead battery), which will suit all riders wanting to make their motorcycle as light as possible. Lithium batteries also have a much longer energy storage life, they can last up to 180 days of charging without any use! They are also more easily recycled than lead-based batteries. However, they also have some disadvantages. In periods of high heat you will have no problem when starting, but during a period of extreme cold (from minus 10 degrees), starting will be more complicated ©, even after several attempts. We can also note that a leak, a bad assembly or a badly placed fall can cause real disasters on this kind of battery by causing spontaneous combustion!

Acid (lead) batteries

Acid (lead) batteries are the oldest. They are easily identifiable thanks to their filler caps on the top. They required regular maintenance, simple but quite restrictive. The new legislation no longer allows the sale of batteries with maintenance. At present, the acid batteries are all ready-to-use sealed batteries. They are very affordable, significantly cheaper than lithium p batteries.ar example, that's why they are still popular. In the event of a breakdown, only professionals are authorized to intervene on your battery.

Gel batteries

Arrived later than acid batteries, gel batteries are actually a derivative of them. The acid present in these batteries is indeed frozen par the addition of a gel which allows them to be waterproof, so they do not need to be maintained and have a reinforced security epar compared to conventional acid batteries due to the fact that they give off very little hydrogen. These batteries are also able to withstand discharges up to 100% and then regain their nominal capacity. They have a very good lifespan due to their very high number of cycles. However, gel batteries also face a few drawbacks. They cannot withstand very high charging speeds due to their internal resistance, so they recharge slowly. The charge parameters must be followed precisely in order not to reduce the battery life. As with conventional acid batteries, gel batteries do not cope with temperature rises very well, beyond 20 degrees we can start to feel the negative effects of heat on the battery. . You will also need to get a suitable temperature regulator to compensate for temperature variations on the battery to avoid damaging it.
