Ampere Time 12V 50Ah Lithium LiFePO4 Battery, Ideal Replacement for 12V 100Ah AGM SLA Battery, More Efficient Output & Much Lighter, 4000+ Cycles, Perfect for Boat, Security Devices, Camping, etc.
  • 【Similar Usable Energy but 5 Times Faster Charging】Our 12V 50Ah lithium battery has 640Wh energy (12.8V×50Ah×100%DOD=640Wh ), which is close to the real energy of 12V 100Ah lead-acid battery (12V×100Ah×60%DOD=720Wh), as the depth of discharge (DOD) of lead-acid is about 60%. It means 12V 100Ah lead-acid battery can run an 80W load nonstop for 9hrs while 8hrs as our 12V 50Ah battery can. And it takes 10-20hrs to fully charge a 100Ah lead-acid battery while 1-2.5hrs of our battery. How efficient!
  • 【Top Protection & 8 Times Lifespan】Ampere Time LiFePO4 battery is made of automotive grade LiFePO4 cells, which has higher energy density, more stable performance & built-in BMS. Compared with the 200-500 cycles and 3-year lifespan of lead-acid battery, our 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. What a huge difference!
  • 【4 Times the Value for Money】Ampere Time LiFePO4 battery ensure 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. For example, the cost per use of our battery is $0.069($219.99/5-year warranty/640Wh=$0.069), but $0.294 of a 12V 100Ah lead-acid battery ($211.57/1-year warranty/720Wh=$0.294). Data shows that buying our battery is the best investment for your money.
  • 【1/6*Lightweight & More Flexible Applications】Ampere Time 12V 50Ah LiFePO4 battery has an extremely lightweight of 11.57lbs, only 1/6 of a 12V 100Ah lead acid battery (about 60lbs), and a 10-year-old child may be easy to tow or move. Meanwhile, our battery has various connections in parallel (max. capacity of 200Ah) and series (Higher voltage of 24V, 36V, 48V), it’s ideal for home back up system such as security devices, lights, solar and outdoor activities like boat, camping, trailer, etc.
  • 【Fast Delivery & Outstanding Service】We are committed to providing you with satisfactory service. Fast delivery because the battery will be shipped from our local warehouse in Los Angeles, California or Dallas, Texas. Professional technical support, humanized return policy & customer service as we provide easy-to-understand operation manuals & online services with quick feedback within 24hrs.

ACDelco Gold B24R 24 Month Warranty Hybrid Vehicle AGM BCI Group 51 Battery
  • Note: Refer a user manual before use
  • Durable design protects against the worst enemy of a truck battery – road vibration (compared to standard flooded batteries)
  • Calcium alloy is optimized to produce a fine grain, corrosion-resistant grid, maximize cycle life and minimizes water consumption for battery durability
  • Fully charged ACDelco Batteries (OCV is >12.5) should be stored in an upright position at temperatures between 32°F and 70°F. When a battery is stored, a very slow chemical reaction takes place between the plate materials and the electrolyte, causing a slow discharge. This reaction, called a self-discharge, occurs more rapidly at higher temperatures. Therefore, it is not recommended to store next to a furnace or other heat source. If an ACDelco Battery is completely discharged, the electrolyte will freeze when stored below 30°F. To prevent electrolyte freezing and battery damage, do not store ACDelco Batteries below 30°F if their OCV is less than 12.5 volts. Check battery every 2 months and maintain a voltage of 12.4 volts or higher
