Rechargable battery problem

Got a set of Rechargable batteried... had them a couple of years, or maybe a bit longer,
They all show 1.43 volts on my voltmeter, but refuse to open the waste bin auto opening lid... and refuse to power the blood pressure machine... ( just give a kind of "thud" and show a zero )..
I have several sets of different makes of rechargable batteries.. some have got the date I bought them... and are reporting over 10 years in regular use...
I am assuming these batteries have gone "memory thick" or something, with the charging... so how can I safely discharge them and re-charge them... ( bear in mind they don`t actually seem to have
enough any "amps" in them for any work ... just the voltage )..
Also note... that when put into a charger.. they do not show any "charge" lights, as others do... ( and the others still show a charge light, even when fully charged... )
