It can be confusing when you browse the Chrome Battery website looking for your application’s battery: the models consist of letters, numbers, dashes, etc. So, let’s break down what each of those stands for. Screen Shot 2014-12-12 at 11.36.37 AM The first three letters in the model name are representative of the manufacturing type. Ours are “YTX,” but some other examples are “MTX” or “GTX.” If you come across a battery with the same title except for these three manufacturing letters, it is safe to assume this is the same battery, just manufactured by a different company.   Screen Shot 2014-12-12 at 11.38.06 AM The numbers define the series of the battery. For example, we offer a YTX12-BS and a YTX12A-BS, this tells us these batteries are in the same series and just differ slightly by power and size. Additionally, we offer “high performance” model batteries that are the exact same size as their counterpart, but they put out additional Cold Cranking Amps (CCA). This is sometimes defined with an “H” in the title. An example of this is our YTX20L-BS and YTX20HL-BS, they are the same size but the 20L-BS only offers 270 CCA while the 20HL-BS has 310 CCA.

A sealed battery means it’s already filled with acid and sealed. A dry battery will arrive with acid separate and requires you to fill it before installation. This earlier post explains dry and wet batteries a bit more. Keep in mind that different manufacturers may have different meanings assigned to their battery models. This information is only meant to help you decipher Chrome Battery’s models on our site. That’s it. Most batteries are labeled on the outside to make replacing them a bit easier. If you’re not sure what battery you need, just check the label on the model that’s currently installed to give you an idea.
