Please read everything below before you bid!!! You must understand possible dangers of Li-ion cells before using them. Visit www.batteryuniversity.com to learn more.
This is the best and one of the most versatile chargers we have tried for protected and unprotected 18650 batteries do date. Will charge up to 4 batteries at once at the full rate.
This is the Australian version, not only does it have an Australian plug, it has been certified and approved for electrical safety, energy efficiency and c-ticked so they are legal in Australia. Version 3 is much better than previous versions.
Don't risk it with cheap chargers as not only do half of them that we have tried destroy batteries quickly, they are also dangerous. Even if you don't buy this charger, please contact me if you would like info on some of the really bad chargers out there. Some puff up in smoke when plugged in, some multipurpose fire hazards are just a 12 volt source that will apply a low current continuously regardless of what battery is inserted.
The S1 max-III treats the battery very well. The best we have seen. You can also stack batteries inside the cover (see pics). Very handy.
The S1 max-III will charge each Lithium ion battery at approx 1 amp continuously (not pulsed) independently regardless of the number of other batteries in the unit or the state of charge of the other batteries. This is the only intelligent 18650 specific charger we have found that provides a clean DC charge (so to speak), everything else we have tried (18650 lose cell specific) produces mini-cycles in the battery => wear and tear.
This has FOUR individually controlled circuits, with individual protection devices (including temp sensor) for each circuit. We have tested many of these. The characteristic seem to be as follows :-
On each individual circuit, upon insertion of the battery, the unit will check for polarity (the battery is inserted the correct way around). It will then provide a quick zap to wake up protected batteries. After this, it will check the battery is in the specified voltage range to begin charge. If the battery is very flat, it will charge at 200mA until it reaches approx 3.2volts, then it will continue at 1Amp. For batteries above approx 3.2volts, it will begin at 1amp. Once the battery has begun the saturation phase (90% charged), the device will flash and hold the battery at just under 4.2 volts. The termination current is 50mA. The device will then stop charging. The battery voltage will fall slightly. If the resting battery falls below 4.1volts, it will re-apply a top up charge. Generally, the battery ends up with 4.15volts or so when finished. We have tested many of these time and time again and none of them have ever over-charged a battery. The version 3 is much better than the previous versions. This is the latest packaging.
This charger now comes with a new and improved, smaller power pack. It no longer covers the power point switch.
The jack is now a 12volt 2.1x5.5mm standard size.

Important tips for using a Li-Ion
Always turn the charger on before inserting batteries
When charging protected batteries, always re-insert or pull
back the batteries several seconds after charging commences.
This breaking of connection /
interruption of the charging cycle will help ensure the over discharge
protection mode of the battery is properly released and help prevent
overloading the charger.
This step is especially important when the batteries
are in protection mode or are fully drained.
See specification below (after pictures).

ALWAYS FOLLOW THE MANUFACTURERS INSTRUCTIONS AND RECOMMENDATIONS FOR USAGE AND APPLICATION.
Some Tips for safer usage and prolonging the life of common types of Li-ion batteries.
Firstly, get yourself a voltmeter.
Never let a Li-ion battery go below the minimum allowable voltage, which is 2.5Volts or 2.75Volts depending on the battery model. Doing so, even for brief periods will permanently damage the battery. It will irreversibly reduce its safety and storage capacity. Dendrites or shunts begin to form between the electrodes inside the cell which could eventually lead to partial or complete internal shorts. They grow like crystals and a combination of factors could lead to eventual failure.
Some factors increasing the likelihood of this happening are the age of the battery, the number of cycles the battery has undergone, the extent and frequency of over discharge, and the charge / discharge currents used. Li-ion packs that have been under stress are more sensitive to mechanical abuse, such as vibration, dropping and exposure to heat.
Lithium-ion operates safely within the designated operating voltages; however, the battery becomes unstable if inadvertently charged to a higher than specified voltage. Prolonged charging above 4.30V forms permanent plating of metallic lithium on the anode, while the cathode material becomes an oxidizing agent, loses stability and produces carbon dioxide (CO2). The cell pressure rises, and if charging is allowed to continue the current interrupt device (CID) responsible for cell safety disconnects the current at 200psi.
Sometimes there may be warning signs of a failing battery and these can include fast self discharge or excessive heat while charging. If this happens or if you have overcharged or over discharged the battery, do not use and send the battery to a recycling depot. The better and newer types of Li-ion batteries include more safety features. Visit Battery University on the internet for more information. Do not abuse Li-ion batteries. Over charging / discharging, excess heat and mechanical abuse are a few things that can lead a battery to thermal runaway. Once this process begins, it cannot be stopped. During thermal runaway, the battery may very rapidly exceed 150DegC and the pressure inside could rise to 500psi. At this point, a safety membrane will burst letting the battery undergo controlled rapid venting with flames. If the device it is installed in leaves nowhere for the pressure to go, the device could explode.
The following examples are an approximate guide only.
Example 1. Sanyo UR18650F 2600mAh, minimum Voltage is 2.75Volts.
At a 3amp continuous discharge, when the voltage under load reaches 2.75 volts, the load must be disconnected. 10 seconds after disconnection, the battery will show approx. 3.4 volts. One minute after disconnection, the voltage will rise to approx 3.5 volts. 24 Hours after, it will show approx. 3.6volts. At 3.6V 24 hour resting, the battery is 98% depleted. It will have approx 50ma remaining capacity and should be recharged before use. At 3.5V 24 hour resting, the battery is 100% depleted and any use without recharging will permanently damage the battery. At 0.5A discharge, the numbers are approx 3.1v, 3.2v and 3.5v respectively.
Example 2. Panasonic NCR18650A 3100mAh, minimum Voltage is 2.5Volts.
At a 3amp continuous discharge, when the voltage under load reaches 2.5 volts, the load must be disconnected. 10 seconds after disconnection, the battery will show approx. 3.1 volts. One minute after disconnection, the voltage will rise to approx 3.2 volts. 24 Hours after, it will show approx. 3.35volts. At 3.35V 24 hour resting, the battery is 98% depleted. It will have approx 50ma remaining capacity and should be recharged before use. At 3.3V 24 hour resting, the battery is 100% depleted and any use without recharging will permanently damage the battery. At 0.5A discharge, the numbers are approx 2.8v, 3.0v and 3.3v respectively.
The rated cycle life is for full charges and discharges. If you do partial cycles, say from 3volts to 4.05volts, you will get around 3 x the number of useful cycles.
Li-ion batteries deteriorate with age. If stored room temp at half charge, the permanent capacity loss is 2% per year. If stored at full charge, they can deteriorate 20% per year. Higher temperatures increase and lower temperatures reduce this. They are shipped from the factory at optimal charge for storage.
