Maintenance free motorcycle battery specs…
Maintenance free batteries (also known as sealed batteries) usually come with the acid in a separate pack.
Once the acid has been poured into the battery and the plastic top has been firmly pressed into place, the battery is completely sealed and shouldn’t require any more topping up or have the acid levels checked.
Maintenance free batteries usually start with the code CTX (e.g. CTX9-BS) and often have the letters ‘BS’ on the end of the battery part number (the ‘BS’ part is used by most manufacturers to indicate that the battery is supplied with an acid bottle).
The 1st letter of the battery code is a manufacturers letter and can be different depending on the battery manufacturer (so YTX12-BS, CTX12-BS, GTX12-BS, DTX12-BS, ETX12-BS etc are all the same battery).
Maintenance free batteries normally have black case and a plastic strip pressed into the top.
Please note – The power outputs stated on this page will vary depending on the make and quality of the battery!
