Default refreshed battery with bc700

I refreshed battery with BC700 charger. Battery with high capacities is not equal to having high voltage. I should use batteries with the same capacities or the same voltage in a group?

If they are in a series then really ONLY the capacity needs to be equal.

Refresh them with lower current is good to have a better refresh capacities or the same?

Probably better, normally we recommend just a c/10 charge for 15 hrs.

It sounds like they might be the NIMH cells AA that are over 2500 mah? If so, they aren't very reliable and lose capacity quickly. They can also self-discharge quickly as they age.

Yes they are all nimh battery. Some AA battery are over 2500mah. It have to take few days to refresh high capacity battery with low current. I'm thinking about paying for buying new battery or electric bill for refresh battery.
Why u said they aren't very reliable and lose capacity quickly? All my Duracell 1000mah AAA nimh batteries lose 1/3 capacity after refreshed.

I'm not sure why the high capacity AA cells degrade quickly , but they sure seem to. The best thing going right now in NIMH cells for AA is probably sanyo eneloops or other LSD NIMH cells. I've been getting 2000 mah cells from HobbyKIng and are very pleased with them. I haven't charged them yet this season and have been using them in my radios.

The capacity will last longer "on the shelf" for sure. Even when comparing the 2000 mah LSD to the 2800 mah NIMH.

I'm not sure about "refreshing" LSD cells.
