Charging Issue

This is well documented on the forum.

Call Lionel and they will fix it under warranty.  The charging circuit is not the highlight of the system as many have gone to regular batteries and turned off the charger.

Yep, I have the #990 and #993.  The #993 expansion charger works well, but the #990 command base gets the stuff too hot for my liking, so that charger is off with tape on the contacts.  I just alternate the CAB2 units in the #993 charger, works fine.

Note that that is after sending both to Lionel for charging updates.

Page 80 says that slow alternating red lights indicate the charger is in a preconditioning state and it will transition to the fast charge when the battery voltage reaches 3 volts. When both are solid green the charge is complete and if they are slow alternating green they are in the top off state and can stay there for 60 minutes. One of my remotes had a bad set off batteries that wouldn't charge in the remote or my own charger. So I'm not to impressed with the batteries and I have replaced them with my own and I charge them in my own charger.

That's what I did.  One of these days I'll drive down the road to Mike Reagan's place and let his crew fix it.

On mine both red lights flash simultaneously (slowly). I wonder if its overcharging and it does that when the voltage goes too high.....

Mine does that too. After a few minutes of normal charging, both red lights start flashing together. According to my manual, this does indicate an over-charge situation. When I first received my Legacy unit, this didn't happen, but it would often go into the over temperature fault mode instead. As many others have done, I switched off the built-in charger and I charge my batteries with a good quality external charger. I rotate through a series of 3 sets of batteries, (1 in use, 1 ready to use, and one on charge.) When I get around to buying a spare Legacy set, I'll send this one in for repair. But as it stands, I'd rather suffer a little inconvenience than to be without my Legacy system for several weeks. (Due to postal transit times to/from Europe.)

I do the same thing Nicole does. That way the base doesn't get overheated and I can use any of my rechargeable batteries in any of my devices. No need to separate the Lionel batteries.
