Should Battery Be Fully Discharged. So if you can run your laptop plugged in or else run it until battery is just below 50 then plug it in. State of Charge is the key metric in AGM battery operation.
Avoid fully discharging your battery as it puts more stress on the battery. This is because the self-discharge of the Ni-MH Battery is large about 10 -15 a month. In most cases but not all this will charge a fully discharged AGM battery.
LiPo batteries need to be discharged and stored with cell voltages near nominal at 38v.
If a battery is charged before it drains and topped off throughout the day you will get more charge cycles. Storing LiPo batteries fully charged or fully depleted can actually damage the battery over time. If NiCads werent allowed to discharge all the way before being recharged they would eventually remember the level of charge they fell to before recharging and act as if they were completely drained every time their charge decreased to that level. This is because the self-discharge of the Ni-MH Battery is large about 10 -15 a month.
