Is there any way to keep this charged? Or is it just batteries?

Li-ion battery packs in laptops have a circuit board that prevents overcharging. Unfortunately it also keeps count of the number of times the battery pack has been through a charge/discharge cycle and eventhough the batteries maybe still be good; IT keeps batteries from accepting a full charge and and that is why they will not keep a charge for as long as they did when new. Also if any battery in the pack goes bad it effects the whole pack because of the way they are assembled.

I have some tips to keep your laptop battery live longer
1.don't undercharging and overcharging,laptops battery can reach 100 degress Fahrenheit and such heat can damage your battery. slowly but sure
2.ideally,you should try to keep your battery charged from 20 percent to 80 percent. i know it's inconvenient to unplug the charger before it reach 100 percent,but try to keep it charged near 80 percent
3.try to charge your battery constanly,and unplug it when you think its almost fully charged,overcharged can heat your battery and damage it
4.keep your laptop as cool as possible,don't try to charge the battery when the computer is turned on,even if the battery is going to 0 and you still need to use it,just shut down the laptop first and charge it,at least until the battery is charged 20%,unplug the charger and turn it on

Well,there are many other tips to keep your battery alive,but i only have those 4,thanks for using fixya

sounds like your alternator then
if alternator is not working, it is not charging the battery whilst driving

You could load test the battery ,to see if its good ,if it is good or new,it may be your stator,or charging system.You could check the voltage of the battery while its running to see if its charging. I found ,they dont like not being started,or sitting for awhile. Ive installed a battery tender ,that keeps my battery fully charged even if you let the bike sit for extended periods of time. Its a very low amp charging system ,then turns itself on and off,to keep your battery fully charged. Sometimes there called Float chargers too.

Normal 0 If the laptop battery is more than 3 - 4 years old then the battery could be worn out. Rechargeable batteries have a finite number of charge and discharge cycles and will lose their charge capacity over time, i.e. won't charge to 100% and gradually the charge reduces until the battery won't charge up at all.
OR The battery shows a 100% charge but when the adapter is disconnected the battery drops off to zero capacity in a very short time.
If the battery drops to an unacceptable charge level then the battery needs to be replaced.

I would suspect that the problem is with the charging system not charging the battery, as opposed to the battery being bad.

If you ran the battery to the point of almost draining it, then the light being orange is from below 25% charge

y hp6365 keeps telling me that i my backup battery is low..i keep charging my phone but the only the main battery is charging..how do i charge or change the backup battery?

As with all batteries, Topping them up by keeping them on charge is very bad for the cells, whats best is a good charge and then a good discharge, looks like you need a new battery - Uniden cordless batteries
