YTX9-BS Battery Cross Reference Chart
YTX9-BS is a very popular Powersports battery, commonly used in ATVs, motorcycles, scooters, snowmobiles, power generators, and other similar applications as a starting battery for smaller internal combustion engines.
YTX-BS is a sealed battery (BS - Battery Sealed), although there are wet/flooded lead-acid batteries made in this size as well.
YTX9-BS Features and Specifications
YTX9-BS battery default physical dimensions are 5.875 x 3.4375 x 4.125 inches (150 x 87 x 105 mm) - that means that any 'standard' YTX9-BS battery should fit into the battery compartment of this size. Terminal orientation is: positive terminal is on the left, negative terminal is on the right side of the battery.
YTX9-BS battery is manufactured by most battery brands, which often have their 'own' label, for example CTX9-BS, BTX9-BS, ETX-9, PTX9-BS, STX9-BS, XCA120R9, MBTX9U, etc.
On average, YTX9-BS battery features 8 Ah 10h capacity and 120-180 Cold Cranking Amps (CCA) value.
As a sealed lead-acid battery, YTX9-BS battery comes as either Absorbent Glass Mat (AGM) or Gel-cell battery - these are low maintenance batteries, designed to be vibration resistant and mechanically relatively strong in order to withstand the use as the Powersports batteries.
Lithium YTX9-BS batteries are much lighter batteries that also cost much more. Also, if the lithium battery is not designed as 'drop-in replacement' for YTX9-BS lead-acid batteries, don't use it in the vehicles with alternators designed for charging lead-acid batteries - in such conditions lithium-ion batteries may easily overheat, catch fire and even explode.
Unless you are a pro driver, go for a good and reliable AGM/Gel-cell battery from a reputable brand.

How to Maintain YTX9-BS Battery?
AGM and Gel-Cell batteries are low maintenance batteries - there is no need (or option) to add distilled water during the operating life of the battery.
The most important maintenance tasks include keeping the connections corrosion-free (which is now much easier since there is no electrolyte spills) and keeping the batteries charged while the vehicle is not in use.
Modern AGM and Gel-cell batteries feature relatively low self-discharge rate, typically in the 3-8% per month range (at 77°F/25°C) and if the vehicle is stored for longer than 2-3 months, it is good practice to disconnect the battery from the electric system in order to prevent parasite loads from discharging the battery.
Also, from time to time, it is good practice to recharge the battery with smart AGM/Gel-cell battery chargers - these chargers analyze the battery before charging and adapt the charging process according to the battery condition. Also, they can even equalize the cells and after the charging process is done, they automatically switch to maintenance mode, keeping the batteries charged over a longer period of time.
Long Story Short: If you are looking for a new YTX9-BS battery, go for the battery of one of the more popular brands.
Their batteries have been tested by countless users in many real-life situations and have stood the test of time.
And whatever you do, stay safe - YTX9-BS batteries are compact batteries, but nonetheless, they are able to provide strong bursts of energy.
