YTX14-BS Battery Dimensions and Specifications

YTX14-BS physical dimensions are (L x W x H) 5.875 x 3.4375 x 5.75 inches (150 x 87 x 146 mm), with a positive terminal on the left and a negative terminal on the right side.

The most common label for a battery of this size is YTX14-BS, with other similar battery labels being used, like BTX14-BS, CTX14-BS, STX14-BS, PTX14-BS, ETX-14, etc.

If the positive terminal is on the right and the negative on the left, then the battery gets the suffix 'L' - YTX14L-BS.

YTX14L-BS is also a popular Powersports battery, but not as a YTX14-BS battery.

Note: there are models of these batteries with four terminals - one battery may be used as both YTX14-BS and YTX14L-BS batteries. Also, some brands label their lithium YTX14-BS batteries as YTX14L-BS batteries, with the "L" indicating that it is a lithium battery.

The following cross-reference chart lists the top 5 most popular Powersports battery models and their most popular brands, YTX14-BS batteries included:

YTX14-BS batteries are mostly AGM (Absorbent Glass Mat) lead-acid batteries, with lithium batteries becoming more and more popular due to their lightweight design and improved cranking Amps.

Lead-acid YTX14-BS batteries feature 12-14 Ah 10h capacity and 190-220 CCA Amps and are charged with onboard chargers (alternator powered by internal combustion engine) or by smart lead-acid battery charters.

Lead-acid YTX14 batteries may be wet/flooded or AGM or Gel-cell sealed batteries ('BS' - 'Battery Sealed') - most models are AGM Valve-Regulated Lead-Acid (VRLA) batteries, offering good and reliable performances, affordable prices, at the expense of somewhat heavier design.

Lithium YTX14-BS batteries feature starting/cranking Amps in the 300-500 Amps range, however, these values are often given for the room temperatures (and are often labeled as "CCA" Amps).

Also, lithium batteries are 3-5x lighter than AGM, Gel-Cell, and/or Wet/Flooded lead-acid batteries, allowing the user to save some weight by replacing a lead-acid battery with a lithium battery.

However, lithium YTX12-BS batteries come with an onboard Battery Management System (BMS) that monitors the parameters of the battery and shuts off the battery from the rest of the electric system if those parameters are not met.

The following cross-reference chart lists some of the most popular YTX14-BS batteries, with their most important features and specifications:

Note: AGM and Gel-Cell batteries are low-maintenance batteries and are highly recommended over wet/flooded cell batteries.

The price of the AGM/Gel-cel YTX14-BS batteries varies between the brands, with the price of top models being shown in the following list:

Lithium YTX14-BS batteries are not as common as AGM/Gel batteries - Lithium YTX14-BS batteries are much lighter than lead-acid batteries while offering the same or even better performances. Also, lithium batteries often cost much more than lead-acid batteries.

Most lithium YTX14-BS batteries may be used in vehicles with alternators designed for charging lead-acid batteries - just in case, it is a good practice to check the documentation of the battery.

If You have a really old motorcycle (The year 2000 or older), before replacing your old lead-acid battery, it is highly recommended to check the voltage charge controller (convert AC electricity from the alternator into 12V DC electricity) and if it is an older design, replace it with a newer one.

Personally: unless You are a pro driver, go for a good AGM/Gel YTX14-BS battery and charge it with an onboard battery charger (alternator + some control electronics) or by using a smart AGM battery charger (set to the proper battery type).

Starting, Dual-Purpose or Deep Cycle YTX14-BS Battery

YTX14-BS batteries are designed as starting/cranking batteries and are not intended for deep-cycle applications.

However, AGM/Gel batteries may be, from time to time discharged down to 50-60% of DoD without adverse effects on the battery's longevity, just note that as the battery gets older and its SoC (State of Charge) gets lower (below 30-40%), its cranking capabilities are also lower.

So, can YTX14-BS batteries be used 'sometimes' as fish finder batteries, the kayak trolling motor batteries, compressor/air pump batteries, and similar? Yes, they can be used, just don't discharge them below 50% DoD/SoC, and be sure to recharge them as soon as possible.

Even discharging them 'once' or 'twice' below 20% SoC (80% DoD) will not harm the battery in any noticeable way, especially if it is recharged fully right away using a smart AGM/Gel battery charger.

However, be sure not to make it a habit - regularly discharging starting batteries below 50% SoC and especially below 20% SoC can significantly shorten their lifetime.

How to Charge YTX14-BS Batteries?

When the YTX14-BS batteries are connected to the vehicle's electric system, the onboard alternator and the control electronics keep the battery charged, regardless of the battery type.

However, when the batteries are, for some reason, taken outside the vehicle, they can be recharged using various battery chargers.

Lead-acid AGM, Gel-Cell, Wet/Flooded, and Enhanced Flooded batteries should be charged with the advanced smart lead-acid battery chargers with a maximum charging current of around 2 Amps.

These battery chargers analyze the battery first and only then start the recharging process, which may, if required, include even desulphation and equalization modes.

And when the battery is fully charged, such smart battery chargers automatically switch to the maintenance mode, maintaining the battery fully charged.

When the lithium YTX14-BS batteries are charged using a battery charger, one must use a dedicated lithium battery charger or intelligent AGM battery charger that also features a dedicated lithium battery charging mode.

Although lithium batteries may accept charge faster than lead-acid batteries, they should be charged with battery chargers with a maximum charging current of around 2-3 Amps using the Constant Current/Constant Voltage (CC/CV) charging algorithm.

Such battery chargers may recharge lithium YTX14-BS batteries rather quickly without overstressing them with the excess current.

Most Popular YTX14-BS Powersports Batteries

A quick look at the YTX14-BS batteries cross-reference chart shows that all these batteries have similar features and specifications.

However, not all batteries are created equal - there are few models that stand out from the crowd thanks to their performances, overall quality, and of course, the price.
