Hi there,
Can anybody help me ? I will start at the beginning so you can get an idea of the whole picture.
Last September I acquired a powabyke shopper. The lady selling it, said that all it would need is a new set of batteries. Fair enough. I bought a set of 12ah 12v batteries (which were the same as in the bike) and they worked fine for 3 months. After that I noticed that they appeared to no longer be holding their charge. I was having to cycle for about a mile every time I used the bike and each day it was getting more cycling. I contacted the company who I bought them off and basically they did not want to know. At work I had them tested with a battery tester and yes they were losing their charge. I cut my losses and after speaking to a work colleague discovered that you could buy 15ah 12v batteries which apparently are better than 12ah. I was told it was the equivalent of say buying duracell and ever ready if that makes sense.
So I went ahead and bought them and everything was fine until about a week ago. Again it seemed to be happening again. The only difference is that they dont seem to continue to lose more charge. I get to a certain point and they then start dying. My bike is used 6 days a week and I cycle the same route every day. (Approx 6.9 miles to work and home again). I charge them as soon as I get to work so the battery is full before returning home and again when I am home so they are ready for the morning. The charger goes green when the batteries are charged and it cuts off charging as the charging unit cools down. I presume? Am i doing something wrong? As the unit is cooling surely it cannot be overcharging them? I do sometimes leave the charger on all night depending on what time I am charging them, but as I have said before as the unit is cooling so it cant be charging right? Even though they are not getting me all the way to work they are still taking approx 2.5 hours to charge which is the same time as when they worked fine. Sorry if it appears that I am waffling on but to me this is the best way to describe it. Any help or advice would be greatfully appreciated.
