I have a few questions on battery charging: 1. If I have multiple chargers running on on the same electrical circuit, does it affect run time or the life of the battery? For example, on a jobsite I would typically have the 4 way charger (DCB104) and 2-4 single chargers (DCB112, DCB101, or DCB102) plugged up to one outlet, possibly even the portable power station as well (charging batteries). Does this amount of load on a single typical electrical outlet affect the charging time or the charging quality of any dewalt battery? I have the full range from small 2ah batteries to 9ah flex volts. It seems that they charge slower which isnt a problem - but my main concern is affecting the charge quality/life of the batteries. 2. Is it ok to charge flex volt batteries on normal chargers? I understand it will be considerably slower to charge a 9ah flex volt on a a DCB112 charger, but does it affect the life of the battery at all? I have a variety of chargers but none of the "flex volt fast chargers". Want to make sure they will do the job and not hurt these expensive batteries. 3. Will charging batteries in low temps affect battery life? I do alot of work in the winter time and don't have much choice but to charge batteries when its cold. How does this affect the life of the batteries? They are usually warm from rundown but cool off fast when they go on the charger.
