12.8V 40Ah LiFePO4 battery overwhelming advantage than lead acid
LFP batteries have a very long cycle life, conservatively speaking, they can reach more than 2,000 times, and the best ones can even reach more than 5,000 times. An ordinary lead-acid battery can be charged and discharged 300 to 500 times.
It is lightweight, weighing only about one-third of the lead-acid battery, 4.6kg, making it easier for you to carry in an RV, boat, or some portable equipment.
More than 95% of the available capacity, so a 40Ah LFP battery can release more than 38Ah of capacity. However, a lead-acid battery can only use less than 50% of its capacity.
With constant power output, you may find that the less power a lead-acid battery has, the less powerful the device will be. However, the voltage of a lithium iron phosphate battery is very stable during most of the discharge process.
Fast charging, lead-acid batteries charge slowly, and sometimes they can’t wait for urgent use. Lithium iron phosphate batteries have much stronger charging acceptance and can charge several times faster than lead-acid batteries.
What can 12V 40Ah deep cycle battery work
Hongyitai 12V 40Ah lithium iron phosphate battery is commonly used in RVs, campers, ship auxiliary power supplies, solar energy storage systems, electric wheelchairs, scooters, trolley motors, golf carts, and UPS uninterruptible power supplies. Basically, all devices currently using 12V 40Ah lead-acid batteries can consider upgrading to lithium iron phosphate batteries.
12V 40Ah LiFePO4 battery upgrade your lead acid battery
It is easy to replace traditional AGM batteries with 12.8V 40Ah lithium iron phosphate batteries. In many cases, it is as easy as changing a light bulb.
Before you decide to replace, you need to do a compatibility check of the new battery’s physical size, voltage and terminals.
After replacement, plug and play, just connect the positive and negative poles. When charging, it is best to use a lithium iron phosphate battery charger. It is best to discard the original charger, which may have a floating charge voltage.
Our BMS has multiple functions such as overcharge, over discharge, short circuit protection, etc. We hope that while you can enjoy the benefits of lithium iron phosphate batteries, you can also feel the ease and convenience of the upgrade process.

FAQs for 12v 40ah lithium ion battery
It is best not to use a lead-acid charger, whose charging mode and voltage curve are not suitable for lithium iron phosphate batteries and may damage the battery or shorten its life. It is strongly recommended that you use a dedicated LiFePO4 charger, which is the safest and most protective of the battery.
Our 12V 40Ah lithium iron phosphate batteries usually come with a 5-year warranty. Please contact us for detailed warranty terms.
Absolutely not. Lithium iron phosphate batteries and lead-acid batteries have completely different chemical properties, voltage platforms, and charge and discharge management methods. Mixing them will cause battery damage, performance degradation, and even cause safety issues.
Yes, lithium iron phosphate batteries are more environmentally friendly than traditional lead-acid batteries. They do not contain harmful heavy metals such as lead, mercury, and cadmium, and have a long cycle life, which in itself reduces the number of discarded batteries. Regarding recycling, they are recyclable.
