20700 battery
A 20700 battery is a cylindrical lithium-ion cell measuring roughly 20 millimetres in diameter and 70 millimetres in length. The larger format may permit different capacity and current ratings but does not guarantee them; the data sheet and device approval are decisive.
01
Classification
20700 battery concerns the power supply and therefore the most safety-critical part of an e-cigarette. Cell chemistry, current rating, protection circuitry and charging method form one unit that cannot be optimised piece by piece. The meaning of 20700 battery shifts depending on whether marketing copy, a user manual or a datasheet is using the word.
02
Practical relevance
In everyday use, 20700 battery shows up in runtime, charging time and how stable the output stays across a tank filling. Fading capacity, deformation or unusual warmth while charging are warning signs to take seriously. In practice the question about 20700 battery comes up together with Replaceable battery – clarifying one of them usually means half-understanding the other already.
03
Handling it safely
Charge 20700 battery only with the released power supply, never unattended and never on a flammable surface. Damaged, swollen or water-exposed cells must be secured immediately and taken to a battery collection point, not to household waste. Nicotine-containing products in connection with 20700 battery are intended exclusively for adults and do not belong in the hands of adolescents.

Not to be confused with
Product copy often puts 20700 battery and Battery in the same sentence, while Replaceable battery describes a different level and must not be equated with them. In case of doubt, it is not common usage that decides but what the manufacturer and – particularly important within Parts & technology – the applicable rules stipulate.

Frequently asked questions
- What all falls under 20700 battery?
- 20700 battery covers every variant that fulfils the same function within Parts & technology – regardless of what a manufacturer calls it in marketing.
- Can I rely on product specifications for 20700 battery?
- Statements about 20700 battery are subject to labelling requirements for the German market but vary in completeness depending on the sales channel. Imported goods are more often incomplete.
- How does 20700 battery relate to Battery venting?
- Battery venting appears in almost every explanation of 20700 battery because both concern the same technical chain. That is still no reason to equate them.
