Motion Computing HC334227332, J3400 manual Battery maintenance, Disposing of used batteries

To determine which battery needs to be replaced, see “Checking battery power” on page 39.

Important: Use only Motion Computing J-Series batteries with the J-Series Tablet PC.

Battery maintenance

To maximize the performance of the tablet batteries, deplete each battery’s charge level to less than 10% every 30 days. To deplete the charge, install the battery on the tablet and use the tablet without AC power until the battery charge is depleted to less than10%. Verify the status of your battery using the battery icon in the notification area of your tablet desktop. See “Checking battery power” on page 39.

Long-term battery storage (not attached to tablet)

Do not store any batteries with a full charge; this can cause a permanent loss of charging capacity. For long-term storage, the battery should be charged to a level between 20% and 40% (two contiguous LEDs illuminated) of a full charge. Stored batteries should be checked every 90 days to determine the charge status. If only one LED or no LED is illuminated, recharge the batteries to a level between 20% and 40%.

For optimum care, store the battery in a cool, dry environment. Never expose the battery to temperatures above 60ºC (140ºF).

Note: In storage, the batteries will self-discharge at a rate of 10% of the total capacity per month.

Disposing of used batteries

When Lithium-ion (Li-ion) batteries are no longer serviceable, the batteries should be sent to a hazardous materials recycling center. Do not discard the batteries in a waste receptacle because they could be sent to a landfill.
