The simple answer is yes, in many cases, you can replace a lead acid battery with a lithium-ion battery, but there are some important considerations.
It can be seen that a slightly higher voltage is required to fully charge the Lithium battery. Therefore, if one were to simply replace the lead acid battery with lithium, leaving all else as is, incomplete charging can be expected for the Lithium battery – somewhere between 70%-80% of full charge.
Lithium batteries cannot just drop in and replace lead batteries can they? Lithium leisure batteries are designed to be a direct replacement for lead batteries. They achieve this by having an inherently closely aligned terminal voltage to that of other lead acid variants of leisure battery including wet, gel and agm types.
A lithium battery is the equivalent to 2 lead batteries. This is incorrect. A lithium battery delivers its power at a constant voltage for far longer and supplies power to near zero capacity before its voltage significantly tails off. This means they deliver nearly 100% of their stored energy as usable energy.
A common desire nowadays is to replace a lead acid battery with LiFePO4 in a system which already has a built-in charging system. An example of one is a sump pump battery backup system. Because the batteries for such an application may occupy much volume in a confined space, the tendency is to find a more compact battery bank.
Discharge Characteristics: Lithium-ion batteries can be discharged deeper than lead acid batteries without damage. This means you can utilize more of the battery's capacity, but it's crucial to avoid discharging below the recommended levels to maintain battery health.
More power – up to 50% more than a managed lead battery to prevent diminished life. Regardless of the load, lithium provides virtually all the available power at a constant voltage no slow fade out. Ultra-long life, several thousand cycles are possible. Lead batteries fail prematurely when they operate in deficit for long periods.
Whilst lithium-ion battery packs offer longer working lives, lead acid are the more cost effective and to a wider degree more environmentally friendly.
If you need a battery backup system, both lead acid and lithium-ion batteries can be effective options. However, it's usually the right decision to install a lithium-ion battery given the many advantages of the technology - longer lifetime, higher efficiencies, and higher energy density.
Lithium has several advantages over other types of batteries, including lead-acid. With a lifespan of 10 years or more, a lithium battery lasts at least twice as long as a standard lead-acid battery. It also doesn't need maintenance like lead-acid batteries, which require an equalizing charge and monitoring to ensure the batteries don't dry out.
Electrolyte: Dilute sulfuric acid (H2SO4). While lithium batteries are more energy-dense and efficient, lead acid batteries have been in use for over a century and are still widely used in various applications. II. Energy Density
Lead acid batteries can pack around 50-90Wh/L in a battery set compared to 125-600Wh/L for lithium-ion. Comparing the type of battery technologies can typically show lead acid sets requiring a volume (footprint and height) up to 10 times greater than a comparable lithium-ion backup solution.
Until this problem is solved, and lead acid batteries are on a par for first purchase and recycling, lead acid remains the most sustainable technology. Today, lead acid batteries remain the first choice for uninterruptible and backup power systems.
Lead acid batteries function through a chemical reaction between the lead plates and the sulfuric acid electrolyte. When the battery discharges, the lead plates react with the electrolyte, producing lead sulfate and releasing electrical energy. The process is reversed during charging, converting lead sulfate into lead and lead dioxide.

How to measure lithium-ion battery capacity: What to check first ✓ Different methods and devices ✓ Important tips and advice ▶ Find out from a professional!.
Lithium Battery capacity relates to voltage. And a multimeter is a versatile tool that can measure both voltage and current. Here's how you can use it to test lithium battery capacity. What You Need: A fully charged lithium battery (e.g., 18650, 3.7V). A digital multimeter. A load (like a resistor or a small device to drain the battery). Steps:
Testing lithium battery capacity helps you: Estimate Battery Life: Knowing your battery's current capacity helps you predict how long it will last before needing a recharge. Monitor Battery Health: Batteries lose capacity over time. Regular testing can alert you when it's time for a replacement.
Connect the positive (+) lead of the multimeter to the positive (+) terminal of the battery. Turn on the multimeter and set it to measure voltage (V). When testing a lithium battery with a multimeter, you must set the readings accordingly. For most lithium batteries, the following settings should be used: Voltage (V): 12.8V – 13.2V
Methods for Measuring Battery Capacity The discharge method involves fully discharging the battery under controlled conditions and measuring the total energy delivered. Ensure the battery is fully charged before beginning the test. Use a resistive load, such as a light bulb or resistor, that matches the battery's rated current draw.
Lithium batteries typically cut off at around 2.5V to 3.0V. Record the Time and Current: Measure the current drawn and the time it takes for the battery to discharge. You can calculate the capacity using the formula: Capacity (Ah)=Current (A)×Time (h)
They are great for recycling or repurposing old batteries, as they help determine whether a battery is still usable. In professional or industrial settings (like electric vehicles or large power tools), testing large lithium-ion battery packs requires specialized equipment.
It is generally not recommended to parallel lead acid batteries with lithium batteries. However, if one must do so, a battery management system can help manage voltage and charge levels effectively.
In theory it is OK to connect them in parallel with two conditions: Each battery must be in a state where it can be voltage charged. This is fine for lead acid batteries unless they are very run down. Very discharged lead-acid batteries have to be charged with fixed current until they get to a minimum voltage, then they can be voltage charged.
Charge them separately with a good (3 or more stage) battery charger and see if they hold their charge for a day (setlling at about 12.6 or 12.7 V), or if they charge at all. If they do, you can probably safely charge them together. There are always risks involved when charging lead acid batteries. Keep them well ventilated and fused.
Most lead-acid batteries charge at a constant 14 4 volts, so charging several in parallel is really just a charge-current issue. If the charger cannot supply enough current it will likely lower the charge voltage to protect itself.
Lead acid batteries will not be properly charged at just 13.8 V. All (not some) lead acid batteries I know need a “bulk” charge voltage over 14 Volts (look up the datasheet of any lead acid battery to confirm this). 13.8 V is just to maintain the charge (“float voltage”).
Very discharged lead-acid batteries have to be charged with fixed current until they get to a minimum voltage, then they can be voltage charged. The power supply is capable of maintaining the fixed float voltage. In practise, I think it's a good idea to put at least a diode in series with each battery just because stuff happens.
In actual practice, people put lead acid batteries in parallel and cycle them that way frequently. Just look at RV's and boats and off-grid installations. A fuse for each battery would not be a bad idea. If you are charging them all anyway then what does it matter if one discharges into another?
