Is it better to charge hybrids in an 8 hour charger or a 15 hour charger?

Hey guys, I have two chargers. The one with the hybrids that it came with that charges for 8 hours I've heard and the a 15 hour Energizer one. The 8 hour one recharges at 350mA and the 15 hour one recharges at 150mA. I calculated it out for the 15 hour one to charge a total of 2250mA and my hybrids are 2100mA. So that appears to work out nicely but I heard charging over a long period of time is inefficient and doesn't exactly equate out to the full 2250. but the 8 hour one charges to 2500mA. Which one should I use for my hybrids? Overcharging at a lower rate wouldnt cause as much damage as overcharging at a higher rate right?

Many cell manufacturers recommend charging between .5C and 1C. .5C for the Hybrids is 1050 mA, and 1C is 2100 mA.

The chargers you're referring to are charge way below .5C.

If you are going to use one of the chargers you mentioned, I'd go with the 8 hr. Hybrid charger.

Oh wow ... I didn't know that charging at a higher rate would actually be better? Is there a reason why these cells prefer to be charged at .5C and 1C? Would charging them slower have any bad side effects?

Missed charge terminations could lead to overcharging cells. Read the "Charging Nickel-Metal-Hydride" section of this article for more information.
