Sometime the smart battery charger does not see a battery because it is too low and report NULL.
When that happens, I put the battery into a dump charger for 30 seconds, then put it back into the smart charger which normally sees it and start the charging process.

Yes, I've experienced this same thing, and I solved the issue the same way. I never leave the battery in the dumb charger for more than a minute, and it's always enough to get it going properly in the smart charger again.
