SOURCE: 18 volt batteries

Yes you can, as long as the batteries are the same style and fit the older Ryobi tools. The Ah rating is a capacity rating. The higher the Ah, the longer the battery will last so the 1.7Ah will just last a bit longer than the 1.5Ah batteries, but yes you can use them on older 18v Ryobi tools. I do it all the time.

SOURCE: Jobmate 18 volt chordless drill charging

About 60 minutes...max 90 minutes. Do NOT leave it on the charger for hours and hours...that just cooks the battery.

And switch regularly between the two batteries...else the one that doesn't get used will die.

Batteries require replacement. It has lost its holding ability. You can try replacing the batteries as the charge holding capacity is lost as per your statement.

SOURCE: I need to know what the output needs to be on the charger of an 18 volt jobmate cordless drill.

During the initial state of the charge, the charger operates in a fixed-current mode. This means that the current will be held at a constant rate until the battery is charged to a bit over 18 Volts. During this phase, the output of the charger will not be 18 Volts. This is done for safety and battery preservation; forcing 18 Volts on a battery discharged down to 15 Volts or less could cause the battery to overheat. If no battery is connected, the charge controller may hold the output low until a battery insertion is detected.

The exact behavior of the charger depends on the chemistry for which it is designed, whether Nickel-Cadmium, Nickel-Metal Hydride, or Lithium ion. If the output of a known-good battery is 18 Volts after charging, and it has normal capacity, the charger is working properly.

However, a bad cell in the battery changes things. If you run a Ni-Cd battery down too far, the weakest cell in the battery may begin to reverse charge from the current coming from the other cells. This usually causes an internal short circuit, and the cell will be stuck at 0 Volts. A battery pack with one shorted cell will read 16.7 -16.9 Volts when fully charged, and the drill will not have the peak power it should. The charger will give you a battery fault indication if it is equipped to do so.

I have a aowa electric bike 48v 500w. the batteries are split into 4 12v 12ah. can i use a lower, lets say 12v 10ah battery or lets say 4 12v 9ah batteries?

yes, the ah has to do with the capacity of the batteries, so the lower the ah the shorter the runtime, and if you have 3 10ah and 1 6ah the capacity of the 10ah batteries will be downgraded to 6ah

Can you add 2-12 v 18 ah batteries in parallel to back up 2-12 volts 32 ah batteries?

hi, you mustn't do that ,,, you can get excessive current flow and that will damage the battery in question
