The slide shows the graphs of the discharging for those green-wrap batteries. let's sum up the results of the battery test. It will take many hours before discussing the results. Tests with a discharge current of 1 ampere and 1.5 amperes and 2 amperes. If batteries succeed in this task, perhaps I will discharge with more high current. Manufacturer declared energy intensity 2700mWh and rated voltage 1.5 volts, then dividing the first digit by the second we get that battery capacity is 1800mAh (=2700/1.5). As GOST recommended, to determine the capacity is necessary battery discharge current 20 percent from the capacitance, that is, the discharge current will be 360mA. Very easy to calculate capacity of these batteries. I will charge these batteries on a specialized charger LC4. But for discharging, I will be using a chemical current sources analyzer -ACK2.5.10.8. Testing will take place as follows.Īfter charge, battery will pause 1 hour as recommended by GOST. And after that, discharge tests will be performed to find out how much current to discharge batteries for capacity determination. Testing will take place according to GOST requirements. Today we will only talk about green extar batteries. I will write a separate review of the charger. Measure the inside battery resistance with devices YR1035+ when passing alternating current with a frequency of 1 kHz, uses 4-wire circuit connection. First instance internal resistance 620 milliohm, voltage 1.525 Volts. Second sample 630 milliohm, third sample 640 milliohm voltage 1.517 Volts and the fourth sample 650 million voltage 1.522 volts.įor to charge these batteries, use this charger - device extra lc4. By the way, specifications indicate that the output voltage in each slot 4.9 volts. It is recommended not to disassemble it to overheat, throw into the fire, short-circuit and so on.īattery weight with first sample - 18.94 grams, second sample almost 19 grams, third sample 19.12 grams and fourth sample 18.9 grams. Battery diameter 14.1 mm and length 50.6 mm. It indicates that it is lithium-ion rechargeable battery core and features that are listed in specifications. And there are also notices -what not to do with these batteries. The negative terminal is flat, while the positive terminal has a furrow that actually separates protection board and converter.įrom the body of the lithium-ion battery, specified the company name and polarity marking. Xstar battery has green shrink wrap plus the output rises above the top edge of battery by about 1mm. The manufacturer stated operating temperature charge possible at extreme temperature, battery discharge from -20 to plus 60 degrees Celsius. This battery has a protection board and accordingly converter which converts the output 4.2 volts up to 1.5 volts. The capacity was declared a little higher - 3300mWh. But these batteries have one difference: the green version battery has LED indicator at the positive output which shows what is going on battery charging.ĭeclared energy intensity 2700 MWh, nominal voltage 1.5 volts, low voltage for these batteries 1.1 volts, maximum continuous discharge current 2A, and net weight of batteries 19.1g. Manufacturer XTAR has already released a similar batteries. Its wrap is in blue-white color. This is lithium-ion batteries with output voltage 1.5 volts from the declared. Today I will introduce Xtar battery review.
