Customer Questions & Answers
What devices are compatible with the 18500 800mAh rechargeable battery and what are the usage requirements?
The 3.7 V 18500 battery is compatible with devices that specify this size (18 mm diameter, 50 mm length) and voltage, such as torches, electronic instruments and some DIY power banks. It is essential to check that the device compartment and electronics support 3.7 V lithium-ion batteries to avoid incompatibility and damage risks.
What are the exact technical specifications of the battery, including actual capacity, dimensions and weight?
The battery has a nominal capacity of 800 mAh, a nominal voltage of 3.7 V, dimensions of 18 mm in diameter by 50 mm in length and an approximate weight of 50 g. These measurements are standard for the 18500 format; however, factory tolerances may vary by ±0.5 mm in dimensions and ±2 g in weight.
What built-in safety protections does it have and what standards does the battery comply with?
The battery includes internal protection against overcharging and overvoltage, helping to prevent fire risks or premature degradation. However, compliance certification with standards such as UN38.3 (safe transport of lithium batteries) is not specified, so it is recommended to check any specific requirements if its use is critical.
What maintenance does the battery require to maximise its service life?
It is recommended to store the battery in a dry place at room temperature (15–25 °C), avoid frequent full discharge and always use compatible chargers to maintain performance. Although it supports up to around 1,000 charge-discharge cycles, demanding use or extreme temperatures can reduce its actual service life.
How does this 18500 800mAh battery compare with alternatives such as the 18650 in terms of capacity and applications?
Compared with the popular 18650 (which usually offers 2,000–3,500 mAh), the 18500 has lower capacity but more compact dimensions (50 mm versus 65 mm in length). It is suitable where space is limited and maximum capacity is not a priority; the 18650 is preferable in higher power-demand applications.
What devices is this 18500 rechargeable battery compatible with?
It is compatible with devices that use 18500-type 3,7V rechargeable batteries, such as torches and similar portable equipment.
How many times can this battery be recharged?
This battery can be recharged up to 1,000 times without losing its capacity.
Does it have overcharge protection?
Yes, it includes protection against overcharging and overvoltage for added safety.
What are the dimensions of this battery?
The dimensions are 50mm long by 18mm in diameter.
