Review: It's a VERY GOOD charger that WORKS. - Certainly not "fussy digital rubbish with gimicks" - This is an "Old School" type battery charger with a proper heavy duty transformer and a meaty bridge rectifier. That is all that is needed or necessary to charge lead acid batteries. I don't want fancy LCD's or blinking LED's on a flimsy printed circuit board. Just a box containing a decent transformer, a rectifier and an analogue ammeter with a needle - that is all that is necessary in a battery charger. This is the second of this model battery charger I've bought for topping-up my 24 volt off-grid battery bank when the household solar panels are giving a good surplus supply of electricity. The batteries are normally charged by a wind generator and then supplemented by these battery chargers when there is a surplus from the solar panels. We use the inverter for heavy power such as washing machine, dishwasher, tumble drier etc. and we now are saving money on electricity bills every month! This charger gives up to 20 amps at 12 volts and up to10 amps at 24 volts. With two of these paired I can often get a 20 amp charging rate into the 24 volt battery bank. That's just under 500 Watts. My only complaint with both chargers, is that the transformers overheated when the charge rate was heavy. i.e. when the inverter is pulling from the batteries AND from the battery chargers. This resulted in the built in thermal cut-out inside the transformer switching off each charger until it cooled. This is a safety feature to prevent overheating. I solved this by cutting a suitable hole in the side of each casing and fitting a 120mm x 120mm brushless mains powered cooling fan to each. (£9.02 per fan on desertcart) (looks similar to a computer fan). The fan is powered from the mains supply inside the charger This has completely cured the overheating problem and I can now drive both battery chargers very hard without them ever overheating and cutting out. THIS is the type of battery charger everybody should use. It punches out a serious amount of amps - especially at 12 volts. A car with a flat battery could be running again in 15 to 30 minutes thanks to one of these. Most of the digital stuff struggles to supply 4 or 5 amps at most. There is very little to go wrong with this type of battery charger - and if it does go wrong it's VERY easily fixed. I also have a very old NON-Digital 12 volt 8 amp battery charger which suddenly failed. For about £5.00 I replaced the bridge rectifier in about 15 minutes. Its as good as new again. You can't easily repair all the digital rubbish. They don't WANT you to repair their rubbish. Plus they stick on all sorts of bells and whistles which 99% of the time you don't need and are often the cause of product failure anyway. These battery chargers are robust, simple and perfect! - a bit like me, I suppose! Thanks for reading this far. P.S. Having now read a few other reviews here perhaps I should point out that the output of ANY battery charger is variable and depends on the load it is charging. In my case, when my 2 x 12volt, 235 amp hour batteries (total of 470 amp hours @24 volts) are nearly full the two chargers only put out a few amps. However, once the inverter kicks in to run an appliance, the output is considerably more - hence the need for the cooling fans when driving it hard. If a battery is flat or almost flat it will take a little while for the current flow to build up and for the battery to begin taking a charge. As the battery approaches full capacity the charge rate (amps) steadily diminishes. Don't simply switch on the charger (ANY charger!) and expect the ammeter to indicate maximum supply! It won't! Also, if your battery is charged so quickly that it gets more than slightly warm, you are very likely to damage it irreparably. Battery chargers have been around for over a hundred years. It's only in the past few years that the 'digital' stuff has been available. This 'Old School', 'Old technology' is simple, tried, tested and proven to work. End.

**Q: Ive put this on both my tractor and 2.8l van. its drained them both completely. im worse off before i used it. am i doing something wrong?**
A: if you left them connected up when you attached the clamps i would expect that, disconnect the battery ,put it on a bench and charge But make sure you connect the terminals then switch on the power otherwise it will blow the fuses. Hope this helps you

**Q: Will this charge big battery for 2.8 van**
A: Yes no problem at all

**Q: Is this normal that the battery voltage rises to over 15v plus it’s the type that won’t stop charging so potentially cooking the battery if left**
A: That was not my experience

### ⭐⭐⭐⭐⭐ Excellent charger
*by M***. on 19 January 2026*

Excellent quality works well

### ⭐⭐⭐⭐ Good 'old school' battery charger
*by R***E on 30 November 2024*

Only criticism is that the crocodile clips are poor quality. It works well; I just recharged a completely flat cat battery.
