I have a Rinpoche Ni-MH Smart Charger. It lists the output as 2.8V, 130mA. The Input is the same. The batteries are 1.2V, or 2500 mAh

You need to put the same energy into the battery that you take out of it. If you have used the 2500 mAH's from your battery it needs to be replaced. Multiply the 130 mA's from your charger by the number of hours to get the mAH's. 130 times 19 hours is 2470 mAH's. 130 times 20 hours is 2600 mAH's. So it will take between 19 and 20 hours to recharge 2500 mAH's with your 130 mA charger.

Your "Smart Charger" will set the recharge time by the condition of the batteries. It is generally recommended to charge brand new Ni-MH batteries for about 14 hrs the first time. This is even true for the so called rapid charge batteries, but, again, only for the first charge. Smart chargers use an LED/resister circuit to "taper down" the charge rate as the resistance of the battery changes.
