Need the l301 li-ion battery for the watch radio

Only the Li-Ion batteries designed to work with the radio can be charged inside the radio. If you have Li-Ion rechargeable batteries such as those you can buy along side the
Alkalines in a store, the answer is no. This type would need to be charged in the style of charger made for recharging this brand/type of battery

li-Ion batteries have a bad habit: whenever fully depleted, they lose a few cells, to the extent that they might not be able to hold a full charge if enough cells are damaged. In other words, repeatedly using a laptop (or any other Li-Ion powered device) to battery depletion can shorten the battery's life significantly. You might want to keep the batteries fully charged whenever possible and avoid fully depleting them too often.
There is also the habit of "re-setting" the batteries by using the "fully deplete-fully charge" procedure. It only applies to niMH or NiCD batteries ( and is used to erase the "memory effect" ) but is damaging to Li-Ion batteries for the reason mentioned above.
so if your battery can not full charge,this mean you need change a new battery for your laptop

Either bad batteries or a bad charger. You can use a multimeter to test for DC voltage output in the charger.

Maybe the AC Adapter Power Cord is not working. If you can't get on the laptop with the power cord then it is bad and the battery might be drained so you have no power source to power up the laptop.
If the laptop works only off the Power Cord and the batteryis not charging, then the battery is dead.

To check to make sure the Power Cord is working remove the battery and let thelatop run for 10 minutes or so.

To check to see if the battery has any charge left in it put the battery in andremove the power cord. If it won't boot or shuts down then the battery is deadand needs to be replaced if the power cord is ok.

according to the schematic I saw yes you can and I think that you will be pleased with its performance, their operator manual even lists the weight of tool with this battery. Makita has a 1 year limited warranty on the Li-Ion battery that you might want to consider if you have the receipt.

We need mark and model and date of purchase. It could be that the battery is worn out

Li-Ion battery and NiMh battery have completely different charging requirements! Li-Ion battery has much stricter charging requirement and the regulator is normally design to trickle charge at 0.1 Current rating @ 4.2V and then completely shut down.
WARNING: if you use a Ni-Mh charger on a Li-Ion battery, then it will erupt and even explode and catch fire!
Bottom line is that the rescued Li-ion regulator is not designed for your Ni-Mh pack and you will never get a full charge with it and you will need a completely different regulator board: you are better off putting in a suitably sized Li-Ion battery with inbuilt regulator but with higher current rating if possible.
Hope it helps! Let me know how you go.

not sure on the charge well have to check out but contact a interstate battery shop thy can rebuild most batteries

Li-Ion batteries cannot be charged efficiently with power supplies or NiCad chargers, they need a pulse charger dedicated to Li-Ion batteries. Also, there is a danger in charging with other sources as Li-Ion batts. will catch fire or explode if not charged properly. Please get a charger that is made for those batteries

A close but not a perfect match....
