celling can be done but at a cost

more than a complete discounted drill kit. Oh well! Back to global
warming:-)

Hi,

How many cells are gone?

None AFAICT. The packs seem to *self discharge* over a few days without
use.

A few charge/use cycles and they recover but having to anticipate using
a drill by the battery charge time is tedious.

Its self discharge that makes them 'gone.' Charge the pack, leave
it for a week and measure the v across each cell. You'll find one or
possibly more that are very low.

Since your priority is cheap, there are 2 options that work:
1. Remove any bad cell(s), wire across where they were and
continue at 22/23v.
2. Re-cell it using poundland AA 25p each cells. Yes, I know... but
its very cheap, and will work at reduced power and capacity for sod
all money, £5, if its ugly but cheap you want.
