    Battery charging question

    Hi,

    Re my kanger emow battery.

    Having read about the dangers of leaving a battery on charge for extended periods particularly if unattended, I sometimes switch them off even though they have not finished charging fully so as to not leave them on overnight.
    Is this likely to result in a shortened battery life??

    Iím hoping not as is the case with most lithium batteries which can be trickle charged i.e. power tools phones etc. whereas NiCad are said to best be fully drained prior to fully charging.

    Thoughts?

    much the same as a phone battery i'd say...... they say to condition a phone battery you use it till it's dead flat then fully charge it, use it again until it's dead flat then charge again until full. (no short 10min charges) this makes the device able to use the %100 of the charge.

    Not a drama doing this from time to time , but you really want to look at giving batteries a good run down and a good charge to maximise their potential... there is NO memory effect in lithium batteries , but they do have a cycle life . Use and not abuse is the key to longevity

    Leaving them charging is the worst thing you can do to a lithium battery, that includes power tools etc.

    Longest life comes from charging the battery to 80% of its final charge voltage, and not draining it right down.

    mmmm totally different to phones batterys then.... I found with phone batts if you charge them when they have 50% charge in them everytime you charge it you'll find that the battery starts to only hold usable charge in that 50% range that always gets topped up. leaving you with a battery that says it's 100% fully charged but really only has 50% of charge in it, soon as you start to use it it'll drain down to below 50% quick as. these were the NiCad type tho

    That would be because NiCad have a memory effect
