Powerowl Charge any number of AA AAA rechargeable batteries to make your charging easier and extend battery lifespan
Charging in pairs is bad for battery lifespan in the long run. This is because even if you start with same brand of recharge batteries, there is always some difference in their capacities. When you charge two unequal cells in a pair, the one with lower capacity ends up being over-charged, which further reduces its capacity over time. So your overall battery capacity will deteriorate much faster.

Powerowl--The smart charge function on chargers checks the charging conditions of the batteries, the temperatures of both the batteries and the charger, etc. This allows the charger to individually charge each battery under the best conditions. 
This function shortens the charging time by 5% compared to the chargers without such function.
