If you have to use the battery immediately after charging it, you can reduce the over voltage by briefly shorting it with a wire connected between both terminals. Now that could be a good way to damage the battery. |

Kaito KA1103
wrote in message ups.com... Based on positive reviews here and elsewhere, and deciding I could live with its ergonomic idiosyncracies, I just bought a new Kaito KA1103. So far, I like it well enough, and the ergonomics are even a little charming. But I have a question about using the radio itself to charge the included NiMH batteries. It's not clear to me how long to set the charging timer for, nor whether there is a risk of damage if the batteries are charged for too long. The spartan "manual" gives a formula of battery mAh / 100 for the # hours to charge, which in this particular case of 4 x 1300 mAh batteries is 52 hours? But the maximum charge time you can set is 23 hours. Does anyone have prior experience charging the KA1103? After playing with the radio for an hour, the battery indicator hit the 25% full mark, and I decided to charge them for 10 hours, based on nothing in particular. Is this too long? Too short? Anyone know? Hi 4 x 1300 mAh charge time is 9-11 hours regards Van |

Be careful about charging batteries within the radio. It has a dumb charger
only regulated by time. After a few charge cycles your batteries will probably not perform to their potential. That can be a problem because this model radio goes through batteries in a hurry. After a while there will probably be one battery that will not fully charge and maybe another that will over charge. It's recommended to get a good battery charger. I use this battery charger: http://www.thomas-distributing.com/mhc401fs.htm It's slow charge option is a good match for the Degen 1300mAh batteries that came with my radio. The batteries won't fry, and each one gets monitored separately so that all four get a full charge. I charged my batteries with a dumb charger a few times before getting the Powerex charger. On the first use with the Powerex charger, I found that one battery took much longer to charge than the rest. After a few cycles the charge time evened out amongst the four batteries and I now get longer playtime. wrote in message ups.com...

I actually have the MAHA MH-C204W Battery Charger, also bought from Thomas Dist, for use with a digital camera I got last year. It only charges NiMH batteries and only has 2 charging circuits, but I assume the technology is similar to the newer 401fs. I'll probably end up charging the 1103's batteries in it as well, but wanted to at least give it a chance to charge its own betteries since it has that feature. |
