Compared with the 300-500 cycles and 3-year lifespan of lead-acid battery, LiTime battery has more than 4000 deep cycles and a 10-year lifespan, which means that the lifetime of one of our 12V 50Ah LiFePO4 battery is equivalent to the total lifetime of 3-8pcs 12V 100Ah lead-acid batteries. 【4 Times the Value for Money】LiTime 12V 50Ah Plus LiFePO4 battery ensures you 5-year warranty while the best-selling lead-acid battery is only 1 year. In terms of lifetime use, the value of our 50Ah battery is almost 4 times than 12V 100Ah lead-acid battery. LiTime 12V 50Ah LiFePO4 lithium battery has 640Wh energy， Which is greater than the real energy of 12v 100ah lead-acid battery (12v× 100ah× 50% DOD = 600Wh), as the depth of discharge (DOD) of lead-acid is about 50%. It means 12V 100Ah lead-acid battery can run an 80W load nonstop for 7hrs while 8hrs as our 12V 50Ah battery can. 【Note】Please do not use this battery as a car battery, starting battery, or golf cart battery.
