12V 15Ah Rechargeable Batteries - Features, Dimensions, and Cross Reference Chart

12V 15Ah rechargeable batteries are relatively small and compact, general-purpose batteries commonly used in cycling applications in toys, tools, electric vehicles, UPS devices, security systems, medical systems, etc.

AGM 12V 15Ah batteries are sometimes even used as starting batteries for small gasoline and dual-fuel internal combustion engines. Still, these engines usually require CCA currents well below the maximum currents of these batteries.

12V 15Ah Battery Features and Specifications

General purpose 12V 15Ah batteries feature physical dimensions of (L x W x H) of 5.94 x 3.86 x 3.98 inches (~151 x 98 x 101 mm) and come with F2 (T2) battery terminals, which are slightly larger than F1 (T1) battery terminals, allowing stronger charging/discharging currents.

12V 15Ah batteries feature the same physical dimensions as 12V 12Ah batteries, except 12V 15Ah batteries are slightly heavier. Also, some brands offer 12V 15Ah batteries featuring physical dimensions of (L x W x H) 7.15 x 3.03 x 6.59 inches (181 x 77 x 167 mm), but many batteries featuring such dimensions have 18Ah, 19Ah, 20Ah or even larger capacities.

Most batteries in the "12V 15Ah battery" group feature a nominal voltage of 12V and a nominal capacity of 15Ah.

However, some batteries feature somewhat smaller capacity for various reasons - for example, Chrome Pro 12V 14Ah AGM Battery, which is a very durable battery, resilient to mechanical impacts, vibrations and different charging and discharging conditions.

On the other hand, some batteries, especially lithium batteries, feature larger capacity, up to 20Ah - for example, the excellent Dakota Lithium 12V 18Ah Battery (Amazon link, the link opens in the new window) features an 18Ah capacity, which is 20% more than typical 12V 15Ah battery.

Note: there are several lithium 12V 15Ah batteries with a capacity in the 16-18Ah range; more on that later in the battery comparison table.

The weight of the 12V 15Ah batteries depends on their chemistry.

AGM vs. Lithium 12V 15Ah Batteries

Sealed Lead-Acid (SLA) Absorbent Glass Mat (AGM) batteries weigh mostly in the 7.3 - 8.9 lbs (3.3-4.2 kg) range, while Lithium Iron Phosphate (LiFePO4) batteries weigh mostly in the 3.0-4.6 lbs (1.36-2.1 kg) range.

Lithium batteries also support a much larger number of charging/discharging cycles. For example, most AGM 12V 15Ah batteries are able to withstand:

  • 160-220 cycles down to 100% DoD,
  • 320-420 cycles down to 50% DoD,
  • 800-950 cycles down to 30% DoD.

On the other hand, lithium batteries, on average, support 10x more charging/discharging cycles.

Note: The actual number of charging/discharging cycles depends on the charging/discharging currents, temperature, brand, etc.

But, lead-acid batteries are much better performers at very low temperatures, they are somewhat cheaper, and when there is a glitch in the system, which is not a "healthy" thing to happen to ANY battery, lead-acid batteries will continue to operate, while lithium batteries will be disconnected by the built-in Battery Management Systems (BMS).

Both AGM and lithium batteries should be charged using advanced battery chargers that support charging modes for the battery type/model being charged. Just be aware that lithium batteries are much more sensitive to charging conditions than lead-acid batteries.

Most AGM and lithium batteries feature a self-discharge rate of 2-3% per month when being stored at room temperature, but lithium batteries don't have issues when being stored in semi-discharge condition (actually, it is recommended), while lead-acid batteries, when being stored for longer period of time, should be attached to a good battery maintainer to keep them fully recharged.

Some of the most popular and best-buy batteries include (in alphabetic order):

Chrome 12V 15Ah AGM Battery

chrome 12v 15ah 1

Chrome 12V 15Ah AGM Battery is one of the most popular AGM 12V 15Ah batteries due to its sturdy design, tolerance to deep discharges (don't abuse that!), and acceptable price.

It is not a lightweight battery - it weighs almost 9 pounds (~4.1 kg).

But, it is a reliable battery, being able to power even larger loads - for example, its Reserve Capacity (25A load) time is ~15 minutes, which is a very good result for a lead-acid 15Ah battery.

Like almost all batteries in this class, it features F2 (T2) battery terminals.

It is a spill-proof, maintenance-free battery that comes with a nice 24-month warranty.

Dakota Lithium 12V 18Ah Battery

 dakota 12v 18ah

Dakota Lithium 12V 18Ah battery comes with an 11-year(!) warranty. Let that sink in - 11 years.

Of course, the battery must be properly charged, discharged, stored, etc., but 11 years is 11 years. And, when charged and discharged properly, it supports 2000+ charging/discharging cycles.

Also, it features a capacity that is 20% larger than the typical battery in this class.

Its maximum continuous discharge current is 18 Amps, but it can provide up to 50 Amps for a very short time (<0.3 sec).

Like all other lithium batteries, it is highly recommended to recharge the battery using a dedicated lithium battery charger or an advanced AGM battery charger that features a dedicated lithium battery charging mode (CC/CV - Constant Current/Constant Voltage).

Obviously, this battery costs more than AGM batteries, but the price is more than justified.

Miady LFP16AH 12V 16Ah Battery

 miady 12v 16ah

Miady LFP16AH 12V 16Ah Battery comes with an 18-month warranty, which could be better for a lithium battery.

But, the battery is rather popular due to the relatively acceptable price and excellent discharge features: 42 Amps max. continuous current, and up to 80 Amps for up to 3 seconds, making this lithium battery the preferred choice for high-drain applications in this class.

The battery weighs ~4 pounds (~1.8 kg), which is ~50% of similar AGM batteries - when the battery is used in electric vehicles, wheelchairs, and similar applications, weight savings lead to decreased load on motor(s), batteries, electronics, etc. increasing the range, speed, agility, etc.

Mighty Max ML15-12 AGM Battery

 mighty max 12v 15ah

Mighty Max ML15-12 AGM Battery is another very popular AGM 12V 15Ah battery.

It also weighs almost 9 pounds, a little bit less than the Chrome 12V 15Ah Battery.

In good Mighty Max tradition, the Mighty Max ML15-12 battery comes with very detailed documentation, including the Constant Discharge Current table, Constant Discharge Power table, and various discharge graphs, which in great detail describe what this battery can and cannot do.

For example, it can provide:

  • 2.05A for 5h down to 10.5V
  • 7.30A for 1h down to 10.5V,
  • 45.6A for 5min down to 9.6V, etc.

Also, when stored at room temperature (68°F, 20°C), it features ~3% self-discharge rate, allowing the user to store it up to 6 months.

Note: personally, whenever storing this or similar batteries for more than 1-2 months, use a good battery maintainer and let it keep the battery fully charged even for longer than 6 months.

All in all, the Mighty Max 12V 15Ah battery is a very balanced unit.

XZNY 12V 18Ah Lithium Battery

 xzny 12v 18ah

XZNY 12V 18Ah Lithium Battery is one of the cheapest lithium 12V 15Ah batteries - and it doesn't even have 15Ah, it has 18Ah nominal capacity. Also, it comes with a 3-year warranty - it could be better for lithium batteries, but as we can see, some very good lithium batteries have even a shorter warranty.

XZNY 12V 18Ah Lithium Battery supports 20 Amps maximum continuous discharge current and 40 Amps for up to 5 seconds - very important for devices, vehicles, and applications that require less than 20 Amps but require stronger starting currents.

The battery can be used to create much larger battery packs, up to 4 in series and unlimited in parallel.

Note: if you do need larger lithium batteries, it is better to buy larger batteries than to connect a large number of smaller batteries. IMHO, of course. For more on this topic, feel free to check our 100Ah Lithium Battery - 12V, 24V, 36V, and 48V Batteries article.

All-in-all, if you are just starting with lithium batteries, go for this model (it is a rather good battery at a very acceptable price) and get a good 12V 5A lithium battery charger - the battery supports 20A charging current, but the 5A charging current doesn't stress the battery.

Long Story Short: Thanks to the improvements in technology, modern 12V 15Ah batteries are mostly lithium batteries - they are lightweight, support a large number of charging/discharging cycles, they are environment friendly, etc.

But, AGM lead-acid batteries are proven technology and still very popular choice, especially for mission critical applications (UPS batteries, for example), or where batteries are needed that are cheap and don't need to cycle a lot.
