HI, I have to agree with you, we thought that his charger was the most likely issue as my batteries seem ok. The confusing thing is that we get the same response from both chargers to his batteries.ie showing full charge with no broken battery lights on.
That makes me suspect his batteries even more, because two things lithium ion batteries don't like...being in the cold and being fully discharged over a period of time.
Those wear out the batteries fairly quickly, and they do have a tendency to show less run time when either one occurs to the battery.
Since they are only occurring with your mate's batteries, I suspect that the issue is related to how they get charged. The broken battery light only comes on if the sensor inside the battery fails, so it won't show a battery that can't store a charge.
Those are pretty expensive batteries, but it's the only place I can find selling them.
Hi, I am still waiting for a reply to my question about the battery cells and control gear that I sent following your post at 9.25 on 6th April.
Ok, are we just talking about the storage cells failing and not the control board. There is a lot of info on the web about fitting new cells into the battery unit as a cheaper fix to buying a complete new unit. The main concern is whether the control board is working or not, obviously if it has gone as well it is a waste of time fitting new storage cells. Does the lack of a broken battery light mean that the board is ok. Also my mate questions the length of time that the battery unit will store uncharged as he thinks a few days to a week would be ok as he tends to run down both batteries and then charge them together. I tend to charge mine on the night that they go flat so that I always have a charged one in hand.
Well I think the term " left discharged for a long period of time" is open to interpretation but my interpretation would not be a few days but a number of weeks. Thanks for your input anyway I have rated you so that you can be paid. I have now opened a dialogue with AEG directly as their literature indicates that there product has some sophisticated control mechanism particular to them. We will see.
