Dummy Battery Interface Camera Can A Battery Charger Recharge Several Batteries In Parallel At The Same Time?

Can a battery charger recharge several batteries in parallel at the same time? - dummy battery interface camera

I recently received a solar battery charger that can recharge 4 AAA again 1 to 1.5 hours.
You can charge AAA, AA, C and D. (larger sizes will take longer)
It is so happened that only 4 in a time where it can go, no 1, 2 or 3 He needs to 4th 2 sets of 2 in series.
Is it possible that they could get, or for the manufacture and use of battery model number of cables for the batteries, as long as the size and polarity are the same.
The idea is that if you can do 4 in 1 to 1.5, then you should be able to do 24 in about 6 to 9.
I ask because I saw where the power is cut twice a year and is away from home for several hours to several weeks. I have the power of the battery more LED lights with 3 AAA batteries, rechargeable batteries, but go dead after a while, so if there have no electricity for a week, they will be charged.
