L16 is a common designation for a tall, deep-cycle battery format used in some off-grid, industrial, and mobile power systems. L16 batteries are not one universal chemistry or specification, so check the exact manufacturer and model before designing a system or choosing a charger.
What is an L16 battery?
Many L16 products are flooded lead-acid deep-cycle batteries. For example, Trojan identifies its L16G-AC as a 6-volt flooded lead-acid battery rated at 390Ah at the 20-hour rate. Its published dimensions are about 313 × 174 × 417 mm and weight is about 46 kg, according to Trojan’s L16G-AC specifications. Other L16 models can have different capacities, weights, terminals, and chemistries; do not apply one model’s numbers to every L16.
What is an L16 battery used for?
Depending on the model, L16 batteries may be used in deep-cycle systems such as floor equipment, renewable-energy storage, or other applications specified by the battery maker. Confirm the required voltage, capacity, cycle profile, installation orientation, ventilation, and charger settings from the exact product documentation. Flooded lead-acid batteries require the maker’s maintenance and ventilation precautions.
How much does an L16 battery weigh and how many amp-hours does it have?
There is no universal answer. Trojan’s L16G-AC is 46 kg and 390Ah at its stated 20-hour rate; other models have different ratings. Amp-hour capacity also depends on the specified test rate, so compare the same rating basis.
See our deep-cycle battery amp-hour chart for help interpreting capacity ratings.
Correction: L16 batteries are not a WWII lithium-ion battery design. The L16G-AC example cited here is a modern flooded lead-acid product.
What is the equivalent of an L16G AC battery?
“L16” alone is not enough to identify a drop-in replacement. Saved product listings include 6V L16 deep-cycle batteries in different chemistries, dimensions, capacities and terminal designs. Check the exact battery model and system documentation for nominal voltage, chemistry, case dimensions, terminal layout and polarity, amp-hour rating and test rate, and charger/inverter compatibility. For a bank, also confirm the required series/parallel arrangement and charging limits. Match the complete specification, not the L16 label alone.
