Hi Bob,

You can almost always do that because chargers typically will either charge the batteries individually or in pairs. Charging one battery at a time is only possible if your charger handles the batteries individually. Look at how many LED’s are on the charger – normally there is one LED for each charge circuit.

Hope that helps.

Sincerely,

Curtis

Hi Joshua,

Thanks for the updated information from Duracell. I’ll change the verbiage to my site to reflect that generally manufacturers do not recommend an indefinite trickle charge. People have always done it anyway for convenience and although constant trickle wears out the batteries slightly the batteries are actually losing a little bit capacity just sitting on a shelf anyway and this way they are always ready to use when you need them.

Sincerely,

Curtis

On your website in the battery info section on trickle charging NiMH, you state that trickle charging is not recommended by battery manufacturers.  However, duracell recommends trickle charging at a rate of C/300 on their website as seen here: http://www.duracell.com/oem/rechargeable/Nickel/methods.asp.  You should update your website with correct information.
