The most widely used are lead-acid batteries (12 V, 6 V, 4 V, 2 V). Among them, depending on the state of the electrolyte, there are:
1. Served with liquid electrolyte (Lead-Acid). They are leaky: the level and condition of the electrolytic liquid, the condition of the plates and their sulfation can be monitored. Need topping up distillate, electrolyte.
2. Maintenance-free valve-adjustable (Valve Regulated Lead Acid)
The 12V battery is available from most manufacturers. 6V models are also popular. Both varieties allow for a sequential increase in voltage.
Please note: if you decide to buy a multi-gel type battery, you are purchasing an AGM sample.
It is believed that the cost of a GEL battery is significantly higher than AGM. But the difference is https://de.life-hacks.fun/page-starten-sie-einen-produktiven-arbeitstag-mit-den-richtigen-websites due to capacity and manufacturer.
Portable devices (phones, tablets, laptops, etc.) use rechargeable lithium-ion and lithium-polymer batteries. Thanks to this technology, the dimensions and the price of the battery are minimized.
The rest of the types based on nickel, zinc, silver and other anode-cathode elements are used less often.
For transport: traction or starter?
If you need to buy a battery for a vehicle, keep in mind that a regular car battery is not suitable for electric vehicles. For a car that is fueled by diesel, gasoline or gas, starter batteries are used. For electric cars
Battery for uninterruptible power supplies.
