I thought this thread might be helpful as to what can and cannot be expected from our chargers, and for those who might be having trouble.
Models rated at 120, and 144 volt outputs have had some revisions, and we continue to refine and improve them. We can also address issues with lower voltage models if there are any.
What you should know:
Our 10 or 12 amp model will not satisfactorily charge a battery rated over 150 amps no matter how long you leave it on. These are only opportunity chargers for batteries over that size, instead, A minimum 20 amp should be used. However, if the display freezes for long periods of time, and has a date code of earlier than 11/08 it needs a revision. We will do this at no charge and return the charger freight prepaid. These models should satisfactorily charge batteries rated at 65-125 amp hour.
20 amp with 230 volt input models that have no fan need to be returned for a new model with fan. Or, if you can provide proof of purchase we don't even need it returned, we will send you a new model at no charge.
The % of charge indicator is not an indication of the % of charge in the battery, it is more an indication of completion of the charge cycle. Small chargers on big batteries will have to start from a lower point than might be expected after only a small discharge, but they are not meant to fully charge the battery anyway.
We believe these chargers will do a satisfactory job for the EV market, but more importantly want to make sure no customer is mislead or disappointed with our products. Hopefully this will add some clarity to what you can expect. Furthermore, feel free to contact us by
or phone 800 658-2841 M-F.
Thanks for your understanding and cooperation.
If allowed, I would appreciate a moderator making this a sticky thread. And I will try and update it with technical info ONLY if needed. This is not an advertisement.
