Your battery will degrade in storage, certainly significantly in 15 years. How much depends on conditions. The mechanisms of lithium-ion degradation are shown here. If you want to put them into storage, the most common recommendation is to charge/discharge them to about 50%. Too much or too little charge on a stored battery cause it to degrade

If it won''t wake after several hours of charging, try another charger and let it sit there for up to 8 hours. You have likely let the battery self discharge to a permanently harmful level, but in most cases you can get it to trickle charge enough so that it will boot again and be of limited use depending on how long the battery was in a harmfully low voltage situation.

A good battery stays in shape for at least a couple of months, even with the ground cable connected. If your battery is good, you should have your car checked. Drawing so much current as to empty the battery in 4 weeks is not normal, and may indicate a serious electrical problem (broken insulation) which will destroy the wiring over time.

6 FAQs about [Battery has been used for a long time but the current is still]

What happens if a battery is not used for a long time?

If battery is not empty and not used for long time - it will be fine. However batteries are not perfect and they slowly discharge without load. If you leave full battery for few months - it may self-discharge and when voltage drop to "almost empty voltage" - it will start degrading and loosing capacity.

How long does a battery last in storage?

How long can a laptop battery last?

Store in a cool place, ideally at room temperature. Check the charge after every two months. If it is below 20%, recharge it to 40 or 60% and store it again. With the above, you should be able to preserve your laptop battery for a long time without use. But there is only so much you can do before the battery starts depreciating or expires.

Do batteries overcharge if kept for a long time?

OEMs have made sure that those batteries are not overcharged even if kept for long. Technically, these days batteries don’t overcharge, thanks to OEM’s implementation of internal protection feature. As soon as the battery hits 100% mark, the internal circuit disconnects the power source from sending any other current.

How often should a battery be charged?

Some factors to be considered include size, chemistry, and manufacturer. You need to check and recharge some batteries every two months to increase their shelf life. Sometimes, the battery might last 6 months before needing a charge. So, there is no general time for all batteries.

Do lithium ion batteries go bad?

Lithium Ion batteries "go bad" when they are stored in discharged state. It is all about battery voltage. If voltage is too low - undesireable chemical reactions will happen and battery will degrade. If battery is not empty and not used for long time - it will be fine. However batteries are not perfect and they slowly discharge without load.
