Battery Other than recharging, is it possible to check a rechargeable battery?

[electricans_son]

I had not used my B&D mini vacuum for a while, went to recharge it but the charger gave no output. Stupidly without checking the price of a new mini vac like the Vax Gator, I bought a new B&D charger but the battery would not recharge. Consequently, for future information I wondered if there is a way of checking a rechargeable battery without recharging as the internal resistance of this B&D battery is 3 ohms. The new charger is charging at the maximum 27 volts and the motor winding resistance is about 0.5 ohm.
