Product detailed description

Lithium polymer (Li-Pol) battery 302040 with a capacity of 200mAh is a thin, light, and powerful accumulator with a nominal voltage of 3.7V (fully charged 4.2V). Energy capacity is approximately 0.74Wh.

The battery includes a protection circuit that keeps the battery voltage from getting too high (overcharging) or too low (over-discharging), which means the battery will be disconnected once it is discharged to 3.0V. This circuit also protects the battery from short circuit.

However, even with this protection it is very important that you only use a LiIon / LiPoly CV/CC charger and charge at 300mA or less. You can also set the charger to 650mA for faster charging. We recommend using our TP4056 Li-ion cell charger, where you can select the charging current by scratching off a jumper and soldering in a different one. Warning! The connector on the charger is not compatible with the one on the battery!

Like most LiPo cells, the batteries we sell do not have thermistors built in. This is why we suggest charging at 0.2C or even less.

If you need larger (or smaller) batteries, we have a whole range of LiPoly batteries

Notes:

  • The battery or accumulator that may be included in the product is subject to a six-month lifetime as it is a consumable.
  • Do not use with NiMH/NiCd chargers! Also, do not overload, short circuit, bend or destroy these batteries. Never charge or use unattended. Always check the battery and circuits for damage, broken wires and short circuits. Like all polymer batteries - they should be used by professionals.
  • This product is not a standalone functional unit and may require professional installation.
  • Product images are for illustrative purposes only and may sometimes differ from the actual appearance of the item. However, this does not change its basic properties.

The manufacturer of our lithium batteries gives the following warnings and cautions:

  • Do not immerse the battery in water or other liquids. Keep the battery in a cool, dry place
  • Do not use or store the battery close to any heat source
  • Use a charger that clearly states that it is compatible for charging the battery and has appropriate charge protection (voltage, current)
  • Do not install the battery with reverse polarity
  • Do not connect the battery to an electrical outlet or other incompatible source
  • Do not throw the battery into fire
  • Do not short-circuit the battery = do not connect the positive and negative poles to each other with conductive material
  • Do not transport or store batteries with metal objects such as hair clips, necklaces, or any other conductive object or material,
  • The battery must not be mechanically damaged, so do not throw it, squeeze it, puncture it, etc.
  • Lithium batteries should only be used with voltage, current, and thermal protection
  • Do not use or leave the battery in a high temperature environment (e.g. in direct sunlight or in a vehicle in hot weather). Failure to heed this warning may result in battery overheating and/or fire or explosion. It will also reduce battery capacity and affect battery life
  • If electrolyte spills and gets into the eyes, rinse and wash eyes with clean water and seek medical attention immediately
  • If the battery smells, gets hot, changes color or shape, or in any way shows abnormal changes during use, charging or storage, remove it immediately from the charger, devices and stop using it
  • If the battery contacts are dirty, clean the contacts with a dry cloth before use
  • Be aware that discarded batteries can cause a fire or explosion. For this reason, before disposing of the battery, insulate the battery contacts with a suitable insulating material, e.g. insulating tape

Batéria sa radikálne nafúkla po cca polroku používania.

Dobrý den. To nás mrzí a není to standardní (dokonce to je poprvé co jsme toto o jakékoliv z našich baterek viděli). Pokud máte fotky, nebo popřípadě nějakou jinou dokumentaci, rádi bychom si je prohlédli. Pokud je to méně než 2 roky, tak vám baterii v rámci reklamace nahradíme za novou.
