Worx grass trimmer Ni-cd battery replacement

Johnmcl7

I have a Worx cordless grass trimmer which is coming up for two years old but unfortunately the battery seems to be on the way out as it's not lasting nearly as long as it used to so I'm looking for a replacement as it seems the warranty doesn't cover the battery past 12 months which admittedly seems normal.

So far the battery prices I've found seem to be about the same cost as the trimmer was which is a bit hefty so I'm wondering if anyone has any recommendations about where to get a replacement from? Aside from the battery, the trimmer has worked well particularly the auto feed mechanism which was a disaster on the Black and Decker and Bosch ones I'd tried before so I'd prefer to stick with this one.

Similar story with mine. Couple of years old and the battery is on it's way out. Like you say the cost of a replacement is nearly as much as a brand new strimmer. Would be interested to hear if anyone has managed to source a cheap replacement.

Think its the same issue with a lot of these.

We have a Bosch battery powered mower and the price of a new battery is half the price of a new mower. The new mowers come with 2 batteries now so better off buying a new one.

Hi Johnmcl7
You can repair them if you are handy enough. Dismantle the battery pack and with a multi meter check each cell for voltage and resistance, should still show small voltage and even resistance between good cells. Try to determine dead cell or cells. Note the amp rating and voltage of each cell. You can buy individual cells off Ebay and the like, cheaper still direct from China. Usually about £1 each. Removing the metal band that they tend to connect each cell to the next, solder a good piece of wire between the replaced cell and it neighbour. Keeping the correct sequence of cells. Replace pack and re-charge.
You can also buy 2nd hand battery packs off Ebay complete.

Hope this helps

Thanks for the suggestion, that may be worth looking into as I haven't found a good price for a replacement battery and given this one hasn't even last two years before it's unusable (tried it today, hardly any power at all) I'm not prepared to fork so much money for another.

OH got his drill battery done and is very pleased. Worth an email to see if they can help and how much.

Thanks for the suggestions, looking at their prices it's going to be around the same price as a new battery unfortunately.

I've got the same issue and can't find the receipt, there is an American worx website that are replacing these batteries free of charge, I put my battery serial number in and I qualify for a free replacement, however it seems it's only US shipping, this is annoying as there is obviously a fault with these batteries.

The batterys are probably a block of sub C types usually But i have seen one with 30 AA batteries, Giving 18 volts. It maybe fairly costly
to replace but the batteries should outlast the cheap original ones.

They are might not be faulty, Just CHEAP and NASTY... They want them to last 1 or 2 years and then need replacing. Its good business for them. Maybe they sourced them too cheaply? Or the manufacturer short changed them?

I have a screwfix brand 24v drill, 2 batteries supplied ones quite good but the other is rubbish. I priced up a new pack and it came out slightly dearer than i paid for the drill.

I looked on ebay, And seems a lot of the batteries sold are fake. And do not have the capacity they sell them as.

4Ah will be lucky to last as long as a 2Ah.

Not sure what people use to test them but seem it mentioned many times what the true capacity was.

One other factor - which is very difficult to overcome - is that cheap power tools often have "fast chargers" which are very poorly designed, and overheat the battery pack, which shortens its life.

Bosch counter this on their professional range by having a sensor in the pack and a fan in the charger to blow air through it if needed.

The easiest way to counter this design flaw in a cheap drill is to avoid deeply discharging it. You can't do this with NiCads, but they aren't used any more anyway.

The batteries that are supplied to the USA are made differently to the ones in the UK so when the details are put into that website it may show that people are eligable for a replacement when you are not.
In the UK you must have your receipt and the warranty only covers the battery for 12 months (it does say in the manual).
The receipt acts as proof of purchase and without it you would have to purchase a new battery or do what others are suggesting above.
