YTX24HL-BS Battery Equivalents and Replacements

YTX24HL-BS lead-acid and lithium batteries are used as starting batteries on motorcycles, snowmobiles, ATVs, power generators, lawn tractors, smaller boats, etc.

YTX24HL-BS batteries can crank surprisingly large diesel and especially gas engines. With improvements in AGM technology, they even tolerate semi-deep discharges - practically, many models act as smallish dual-purpose batteries. But, their primary role is to provide strong currents during short periods of time ...

YTX24HL-BS Battery Features and Specifications

YTX24HL-BS battery features physical dimensions of 8.0625 x 3.4375 x 6.375 inches (205 x 87 x 162 mm), with the negative battery terminal being located on the left - hence "L" as part of the YTX24HL-BS label.

Note: some YTX24HL-BS units feature quad terminals and can be labeled as "YTX24HL-BS" or "YTX24H-BS" batteries.

Also, YTX24HL-BS batteries are designed as "High Performance" batteries, hence "H" as part of the YTX24HL-BS label.

Most YTX24HL-BS batteries on the market are designed as Valve Regulated Lead-Acid (VRLA) Absorbent Glass Mat (AGM) batteries, with some Gel-Cell lead-acid batteries also being present - wet/flooded YTX24HL-BS batteries are being practically phased out.

AGM and Gel-Cell YTX24HL-BS batteries are vibration-resistant, spill-proof, maintenance-free lead-acid batteries that feature a nominal voltage of 12 volts, 21-24 Ah 10h capacity, 300-350 CCA Amps, and they weigh 13-18 pounds (~5.9 - 8.2 kg). Thanks to their sealed design, battery terminals corrosion is decreased significantly and, in many cases, completely gone.

If they are used as dual-purpose batteries (and they should NOT be used as such, at least not on a daily basis), they can easily withstand discharges down to 50% DoD and recover properly when charged with an intelligent AGM battery charger that also features desulphation and equalization charging modes.

Note: If You are looking for a similarly sized general purpose/deep cycle battery, feel free to check our 12V 18Ah, 12V 19Ah, and 12V 20Ah+ Lithium and Lead-Acid Batteries article - these batteries are much better choice for deep cycle and similar applications than YTX24HL-BS batteries and have a very similar dimensions of 7.15 x 3.03 x 6.59 inches (181 x 77 x 167 mm).

mmg ytx24hl lithium

Lithium YTX24HL-BS batteries are not as common as AGM/Gel-Cell YTX24HL-BS batteries, but they offer great weight savings and somewhat stronger cranking currents.

Lithium YTX24HL-BS batteries should be charged either with the vehicle's onboard battery charging system (alternator, combined with some charge controller) or using a dedicated lithium battery charger (or AGM battery charger that features a dedicated lithium battery charging mode).

By replacing the AGM YTX24HL-BS battery with a lithium YTX24HL-BS battery, users can save 9-14 pounds (~4.1 - 6.4 kg), which is often not a very significant weight saving for ordinary users and recreational activities.

However, for high-performance applications, a weight saving of 9-14 pounds can be the difference between winning and losing :)

When buying a new YTX24HL-BS battery, it is very important to choose according to battery features and specifications, your own needs and requirements, but also what other people have to say about them.

chrome ytx24hl bs battery

For example, the Chrome YTX24HL-BS battery features a somewhat lower CCA rating than other batteries (300 CCA vs. ~350 CCA), but due to the combination of balanced design, strong casing resilient to vibrations, and mechanical impacts, acceptable price, this battery is one of the most popular YTX24HL-BS batteries.

Other very popular models include (alphabetic order) Energizer TX24HL, Mighty Max YTX24HL-BS, and Yuasa YTX24HL-BS battery.

What Kills YTX24HL-BS Batteries?

The greatest enemies of YTX24HL-BS batteries are summer heat, long inactivity periods, mechanical vibrations and impacts, and improper charging during winter and summer.

  • Summer heat - during summer, if possible, keep your vehicle (and thus the battery) in the shade or preferably in an air-conditioned area. If possible, the battery compartment on the vehicle should be well-ventilated, keeping the battery's temperature as low as possible.
  • Long inactivity period - when the battery is stored during winter, it can be left connected to the battery maintainer, keeping the battery fully charged and cells balanced. If it is not possible to store the battery with the maintainer connected, fully recharge the battery and store it in the cold area - with most AGM batteries featuring a self-discharge rate of <3%, especially at lower temperatures, most AGM YTX24HL-BS batteries can be stored that way for at least 3-4 months without any side effects on the longevity of the battery.
  • Vibrations and mechanical impacts - AGM YTX24HL-BS batteries are very vibration resistant, especially when compared with flooded YTX24HL-BS batteries. However, vibrations and mechanical impacts can physically damage the battery. To prevent that, be sure that the battery is fixed firmly at its position in the battery compartment, and if required, use some rubber mats to decrease the vibrations that are transferred from the vehicle to the battery.
  • Improper charging of lead-acid batteries during summer and winter is caused by charging the batteries with the battery chargers not having a temperature probe, causing the batteries to be overcharged during summer and not charged completely during winter.

One of the most popular battery chargers in the 2 Amps class is the NOCO GENIUS2 2A Smart Battery Charger (Amazon link opens in the new window) that is able to charge 6V and 12V lead-acid (wet/flooded, Gell, AGM) batteries and 12V lithium batteries.

It also features a temperature probe, can be used to (try to) revive deeply discharged batteries (down to 1V), can be used as a battery maintainer and desulfator, has a rather wide temperature range, etc.

It is one of the most popular battery chargers in this class.

Note: most YTX24HL-BS batteries feature a nominal capacity of ~21Ah, and charging them with ~0.1C some people consider too slow. Personally, charging these batteries with currents up to 0.15C (3 Amps) is, in my opinion, fine, but using 0.25C (5 Amps) chargers is perhaps too much for them. Just my 2c.


ytx24hl bs battery mLong Story Short: YTX24HL-BS batteries are rather compact batteries that are able to provide strong currents required for cranking small to medium gas and diesel engines.

YTX24HL-BS AGM/Gel-Cell batteries are practically a standard type of YTX24HL-BS batteries, with the lithium batteries slowly appearing in this battery size as well.
