Here is a question we received from a customer today. I thought it was worth sharing…
Hi,
I have MH-C204W battery charger I bought from you about 2 years ago. Its instructions sheet states \”do not mix batteries of different capacities ….\”. Your website states \”.. you can charge two different sets of two rechargeable batteries …\”. Is this true for all MH-C204W models or is this a later update to this product.
This is true of all MH-C204W battery chargers. The MH-C204W charges AA and AAA NiMH rechargeable batteries in pairs, and the pairs should match. However, you could have a different capacity and/or brand in slot 1&2 to what you are charging in slot 3&4. Similarly, you could charge a set of AA batteries in slot 1&2, and a set of AAA batteries in slot 3&4
I have also noticed that at the end of the quick charge cycle the batteries are only about 90% charged but leaving them on for another 2-3 hours adds another 8% or so to the voltage. Is this what should normally be done for a \”fuller\” charge\”?
The 204W will charge the NiMH batteries at a rate of 2000mA until they are almost full, approximately 97% of capacity. The battery charger then detects that the NiMH batteries are almost full by constantly monitoring the voltage, and it will switch to a 50mA trickle charge. If you leave the battieries in the charger for another hour or two, you will get another 2% or 3% charged capacity.
