More info

Invercar 3800 6/12V 3.5A Solter intelligent charger for car and motorcycle batteries with the latest technology that has been designed to intelligently charge lead-acid, AGM, gel (cars and motorcycles) and Lithium-ion batteries up to 120A. The charging process is carried out in 8 stages, starting with a diagnosis to verify that the battery is connected and that the voltage is correct to start charging. If the voltage is very low, a desulfation program begins that can last 5 hours. Once it is at an optimal voltage level, the stepwise constant current charging begins, followed by charging at maximum current until the charging voltage for the battery is reached and the absorption to maintain it. To ensure that the battery maintains a charge, constant analysis and monitoring is carried out. It includes a charging memory function that, in the event of a power outage, will automatically memorize the charging status to resume the charging process once the power is restored. In order to use it, the device comes with a cable with clips. Manufactured by Solter.

Lithium batteries
Li-Ion or Lithium batteries are one of the most common batteries used today.
We can find this type of battery in mobile phones, wireless headphones, UPS, smartwatches, cars, etc.

Lithium is a very light metal capable of generating ions easily, making it ideal for the manufacture of batteries.

Unlike other types of batteries, they are a bit more expensive, but in return, they are much smaller and lighter, capable of doubling the duration of a Ni-Cd battery.

Thanks to their composition, they can be manufactured in different shapes, adapting to the device where they are to be located, and their low memory effect makes them ideal for any type of device.

Summarizing their positive points:
  • Easy to find
  • Many different sizes and shapes
  • Small size
  • Lightweight
  • Capable of accumulating more charge
  • Less memory effect
  • Long lasting
  • Low self-discharge rate.
These batteries also have their negative points, namely:
  • Lifespan of about 3 years.
  • Limited number of charges, between 300 and 1000.
  • They are more expensive.
  • They can overheat to the point of exploding.
  • Poorer performance in cold conditions.
  • Highly variable voltage.
Within lithium batteries, we can find 3 types:
  • Lithium-ion polymer batteries.
  • Lithium iron phosphate (LiFePO4).
  • Olivine-type lithium iron phosphate batteries.
