Hey, got some questions about running a partial dual battery setup. the battery that came with my laptop is dying and only lasts about 50 minutes now on a full charge, bought a new battery that lasts about 3 - 4. If i have them both in the laptop they both discharge at the same time. Is there anyway I can set them to failover, so when one gets to like 3% the other one kicks in? I also noticed that when i have 2 batteries in one was at 100% the other old one was at 87% but wasn't charging, had to take out the new one and switch the battery bay for the old battery to start charging...anyone have any suggestions?
