Maypole 4A Dual Voltage 6/12V Electronic Smart Car Battery Charger Fully Automatic 5 Stage Charging Cycle Lead Acid AGM

I already own a CTEK MXS 5.0 trickle charger, which I use on my wife's vehicle. After my 318D AGM battery gave up the ghost decently- due to lack of use during the pandemic as I work from home - and was replaced, I started shopping around for a cheaper trickle charger. The CTEK is excellent, but at around £60 I couldn't afford another one. I came cross this MayPole charger quite by accident, saw the good reviews and decided to give it a go. On opening the package, I was very impressed with the unit itself as well as the manual which was in very clear English. The unit looked and felt like a high quality product. The clear backlit display with the digital display of the charging voltage is a welcome feature (the CTEK has only LEDs). The unit comes with both crocodile clip and ring terminals (if you want a semi-permanent solution), and connects to the lead from the unit via a standard SAE connector (again a welcome change from the CTEK which uses it's own proprietary connector). I plugged it in, and given my AGM battery was relatively well charged to start with, it started charging at 'Stage 2' and within a few hours transitioned to the 'Stage 3' or float phase, with a float voltage of 13.8V being maintained consistently throughout (exactly as recommended for float charging of 6-cell AGM batteries). It's been rock solid since I plugged it in a week ago. I really don't see a difference between this MayPole and the CTEK chargers, except this one is about a third in price. Highly recommended. I wish I had come across this before I bought my CTEK. On another note, don't let your AGM battery lose charge - as they say it's next to impossible to recover these batteries once they've lost their charge beyond a certain threshold.

I am loving these (Purchased 2 of them) no, they are only small and it does take a while to get a bigger battery fully charged, but no fear of over charging and they perform great.. using them to top up parked vehicles and condition the leisure battery of my camper when not in use.. Have to update. Still a great bit of kit. “Intelligent” chargers like this will not charge a severely discharged battery, if you flatten a battery to below the chargers threshold, (normally around 9v) then you need a cheapo “dumb” charger to bang in volts. (I use a £10 one from Tesco as my backup for this) A typical 12v battery is considered fully discharged at 10.5v and anything below this is likely to damage the battery especially if left for any length of time. You should never leave a typical lead acid “car” battery discharged for any length of time.. These maypole chargers are ideal for maintaining batteries that are stored or used infrequently or where an alarm etc is drawing current on a parked vehicle. They will fully charge a big battery over a longer period. If you want faster charging, especially on bigger batteries, then buy a bigger AH charger... Slow charging is much better for your battery... They automatically charge as needed and even if the mains power has been off, restart automatically too.. I can’t fully comment on voltage reading accuracy as I don’t have a calibrated volt meter, one unit does over read slightly compared to the other and my volt meter.

Superb bit of kit. If you’re not using your vehicle for a while chances are things like the alarm will still be draining your battery, especially in winter. Cold weather and batteries don’t get along.......this is the fix! So easy to use, run an extension reel to your car lift the bonnet connect red clip to positive and black to the bodywork for an earth and turn it on. This isn’t a booster but a trickle charger, depending on the stage of your battery it takes an hour or two to top up the battery. The slow charging is much better for the battery. It comes with winter mode and won’t let you reverse the polarity by mistake. Connect it to your unused car every 7-10 days and just leave it to do it’s thing. Amazing value and so easy. For the price it would be mad not to have one around.

Easy to use 12v/6v battery charger, just connect to the battery switch on, will automatically select battery type, or use the mode button to select battery type if is a AGM, or you want winter charging mode. Works well screen changes from green to red when charging, and shows a symbol of a battery same as on your phone for the state of charge, very pleased with it, but if your 12v battery is really flat, it tries to select 6v mode and will not charge the battery, the mode button will not work to change to 12v, I had to use my old charger to top it up first before it will charge, the battery was almost dead flat, for the price it is good value.
