The battery no longer holds enough charge to finish trimming the yard. Initially it would charge enough to finish. Is the battery covered under the warranty?

Usually an old (or older) battery will no longer hold a charge ... or will only hold a small charge (that will let you run the GPS for only a few minutes).
Often, when the TomTom device is always connected to the charger (in a vehicle), where it charges every time the car is turned on, whether the TomTom is being used or not, the battery gets charged (partially or fully) often enough to use up the "maximum number of charge" cycles for the battery. Hence, it will no longer charge properly or hold a strong charge.
Like for all lithium batteries, it's better if your device is not always connected and being charged (whether you are or are not using it). The battery will last longer and it will still be able to hold a stronger charge.

call the company

you need a new battery. It is possible that the battery may be fried.

Is this a battery powered mower?
If so, it sounds like the battery is dying. Batteries do have to be replaced, but 3 years seems like a short life. Ask your dealer before buying another.

Well your battery problem is quite simple. Litium batteries have a life and as the cells deplete, they will not hold as much charge as they once did. The part number for your unit is Worx WA3512.1 and can be purchased for about $53.00. As far as the spool retainer clip is concerned, you will be looking for a hard to find part. Here is the good news, you can purchase a brand new WORX GT WG150.1, which is the model you currently have, for only $95.00 on Amazon. I hope this helps you and let me know if I can be of additional assistance.

Laptop batteries worn out with the passage of time and their charge holding capacity decreases.
The battery now has very less charge holding capacity (equal to 4-5 minutes), that's why it says it is 100% charged (capacity of 4-5-minutes).
So, it is recommended to replace the battery with original battery as it would last longer and serve you better.

Let me know if any further clarification/ assistance is required.

Good Luck!

They are a pig to change, but if you want to do it and you have the facilities and the patience, here's what you need to know:

You require 2 off AA cells with solder tags. The originals are 1600mAh and so you should obtain replacements of at least this capacity. I obtained 2000 mAh batteries.

There are four hidden screws which you need to access. At the base (where the charger plugs in) you need to remove the cover. Insert a thin screwdriver blade in the side furthest away from the connector (on the side of the base) just to one side of the centre. With luck the cover will pop off with no damage, but if you do damage it it really doesn't matter too much if it can't be refitted later. Beneath this are the first two hidden screws. Remove them. Then remove the trimmer - first open the shaver head and remove the cutter assembly by pulling it up from the pivot. Press the trimmer slide inner arms towards each other and disengage the pivots.The trimmer itself can then be removed by carefully unclipping it. Then squeeze together the arms from which you have just disconnected the trimmer and the whole grey/brown assembly will come out revealing two more screws, which should be removed.

The back will then come off revealing the batteries. You'll need a sharp craft knife to cut through the blob of silicone attached to both batteries, taking care not to damage the temperature sensor embedded in it and soldered into the circuit board underneath. Cut through the battery solder tags (the cut ends can be more easily removed when the batteries are out) and remove the batteries. The ends nearest the shaver base are joined together by a short wire which is likely to also be embedded in the silicone - you'll now be able to get this out for reuse. The batteries have plastic tape to provide insulation on the terminals but this can be easily removed at this stage.

Solder in the new batteries - the red wire from the circuit board to positive on one battery, the white wire to negative on the other one. Link together the positive and negative 'other ends' nearest to the base - the idea is to have two 1.2V cells in series to give 2.4V. Insulate the exposed battery terminals with insulating tape.

Replace the back after checking that the motor runs indicating you have no problems. Reassembly is more or less the reverse of disassembly, making sure that the back cover gasket is properly in place.

Note you do not need to get access to the top of the shaver - other than removing the cutter block. You should now be in business!

Final note on charging: initially charge until the case gets noticeably warm - probably around half an hour. Then use the shaver normally until it cuts out - probably long after '0' is shown in the display. Then recharge until '60' shows in the display. Stop charging at that point. Don't leave the shaver plugged in - overcharging is the problem and it will shorten battery life if you charge beyond the point where '60' shows. Although if you have used larger capacity cells than original you'll get more than an hour on a full charge, it's kinder to stop a bit short. It really does make a big difference.

How large is your yard? On a small yard (like a townhouse front & back yard) the trimmer should last long enough to do the yard a couple of times before needing to be recharged, but it depends on the individual yard, how many weeds you have, and whether you keep it running a long time.

If the trimmer charges at all but not for a very long time, it's either the charger or the battery. Check the charger when it's charging to make sure the red light stays on -- if it goes off or blinks, you need a new charger. If the charger light stays on but the battery doesn't hold a charge, you need a new battery.

Hope that helps!

Your battery is dead and will no longer hold a charge. If it is a newer computer, then it may be defective and covered under your warranty. If it is an older computer, this is the unfortunate thing about rechargeable batteries...eventually they will no longer hold a charge.
