I always thought the risk of non-genuine batteries was fairly low so long as they weren't left plugged in or connected to the tool. May be wrong though.
Avoid using any copy of batteries they often fail and can cause firesJust wondering what experiences people on here have with cordless batteries. I have bought four generic Makita 5 amp batteries ( not genuine Makita ) . One was a dud and Amazon sent a replacement, no problem. I put two on charge yesterday and found one overheating with leakage of electrolyte. I had left it about two hours but it should have stopped charging when full. Needless to say it's now a write off.
Now I hear that the batteries of E- bikes are exploding with loss of life in the UK. Once they ignite they go up like a firework.
There is a huge difference in price between genuine Makita ( about £70 compared to £30 ) but I would be very reluctant to buy the generic batteries again. Has anyone else had any experience of this ?
I think the problem with many of the cheap batteries is that they don't have the circuitry to ensure safe charging. Crucially good ones have temperature sensors to monitor the temperature of the battery as it charges, and work with the charger to ensure that the battery is charged at the appropriate rate, and stop charging or revert to a maintenance mode once charged. I would be willing to get that the exploding e bikes are all cheap Chinese jobs that don't have these features. You pays your money etc, but when the price of them going wrong is to burn your house down, or worse, then maybe not such a bargain.Just wondering what experiences people on here have with cordless batteries.

I think you’re confusing what a CE means (though now it’s a UKCA for sale inside the UK).Thanks for all that. If the CE logo is a con how are we to know what is genuine or not. ? Looks like we have to shell out our £70 and take their word for it. I suppose it would be better to stick to a well known Makita dealer. ?
CE mark means nothingThanks. It's a twin charger and the other battery charged up no problem. What annoys me is that the batteries had very little use - I have used them in gardening tools a few times only. The electrolyte was quite corrosive as well, melting the plastic charger case a little. It looks like there is no option but to plump for OEM batteries - hopefully they would carry the European CE mark. ?
Spot on. If they can accurately copy the product, and some fakes are virtually indistinguishable from the genuine article, then they can certainly fake a label.Thanks for all that.

Sounds like a lucky escape and good on you for hearing it ..Years ago I bought a copy Festool battery which worked fine but that was back in the days when everything was NiCad plus it was made in Germany. I have heard too many horror stories about the unbranded Li-ion Makita copy ones to risk trying them despite the tempting price. I like the small 2ah batteries for my 18v Makita drills and they are often more expensive than the higher ah ones
A few weeks ago I was woken up in the middle of the night by a bang followed by an acrid smell, an unbranded phone charger/USB plug I got off Amazon had decided to give up in rather spectacular style. It left an impressively large black mark on the socket and wall, I won't be clicking "Buy it again" on that one.
Chinese export I believe!Thanks for all that. If the CE logo is a con how are we to know what is genuine or not. ? Looks like we have to shell out our £70 and take their word for it. I suppose it would be better to stick to a well known Makita dealer. ?
Definitely good advice and worth heeding..An additional warning for those who use adapters. Different manufacturers have different numbers of terminals on the battery packs, and often these are used for safe charging, rather than safe tool running. A DeWalt 18V zodiac battery for example will use two large and two small terminals on the tool, but the charger will use every terminal. SO if you use an adapter, please at least make sure you use the correct charger, don't use the adapter for charging. (I am a Dewalt engineer, have been for the last 20 years, and I have been working on cordless tools and battery packs for the last 10 years, so please trust that I know what I am talking about.)
