Yuasa YTZ14S Replacement Batteries and YTZ12S Upgrade

Your original Yuasa YTZ14S also referred to by stock code YUAM72Z14 had cold cranking amps (CCA) of 230 and 11.2 amp hours (AH). It measures 6 x 3 7/16 x 4 3/8 inches and weighs approximately 8.6 lbs. The warranty period ranges from 6 months to 1 year depending on where the battery was purchased. You may want a longer warranty or higher CCA or something made in the USA. Compare these OEM specs to some of the brands below and buy the right battery for you!

Contrast YTZ12S and YTZ14S

Comparing these two batteries, one would discover that they are identical in size. They are marginally different in output with the YTZ12S (YUAM7212A) having 11 Ah instead of 11.2 Ah and 210 CCA vs. 230 CCA. One manufacturer, Moto Classic, decided to make life simple for bike owners and combined the two batteries into one SKU while maintaining the higher specs and offering a 30 month warranty. They may call that innovative, we call it brilliant!

The Generator Battery Issue

There has been some confusion regarding the battery needed for some Honda and Honeywell generators. We have written a couple blog articles covering this topic to help guide you to making the right choice.

In short many of these generators have a GTZ14S labeled battery in them which in most cases is compatible with the YTZ14S labeled batteries. However, many of these come with a non-standard version which can reek havoc on your plans and cause much frustration, time and money loss. If you are looking to replace a generator battery we would suggest clicking through and reading this article first and then click on the link in the comments to a second article for Honeywell generators.
