TecMate OptiMate 4 Quad Program 12V Battery Optimiser

When a RING battery conditioner failed and allowed a battery to become seriously discharged, this device has almost completely saved the battery. A little less than full power but serviceable for the foreseeable future. Looking forward to relying on it for years to come.

Absolutely zero fuss or hassle to use. Display is logical and really can't fault any of the optimate stuff. Excellent chargers and value for money. /like that it comes with a hook on the body so you can hang the charger above the bike

This is so easy to use and hardly needs an instruction booklet it is so simple. The push of the button selects between standard acid/gel type batteries and LI ion batteries and then a canbus setting specifically helpful when using on my BMW.
Quality made and works perfectly And if it lasts as long as my other Optimate optimisers have I’ll be very happy

So far so good, a bit slow in initial check, but once left on for a bit, it gives the expected readings, this may be because of the lithium battery and setting.

Well after having my previous Optimate 4 that lasted over 12 years when it fail thought I see what was about, wasn't really much of a choice when you come to slowly charging you batteries. The new 4 Quad, it covers Std Lead Acid, AGM-MF/Gel and LFP, so no need for different charger make life easier, with easy to understand lights as to the state of your battery,,.
Out of my three batteries that looked dead only one failed to be recovered which more than save the cost of the Optimate 4 Quad

I needed a charger after my bike and car were standing for 3 months.
I read reviews before I made my purchase, a lot of comments were made about the instructions; I did manage to figure it out but it wasn't as easy as I would have liked.
The Optimate told me that both of my batteries needed replacing, but it did charge them enough that I could get both vehicles running in the meantime.

Extremely well made charger. The plug in connections are very positive. The instructions are excellent too.
Would definitely recommend this product.

Superb item that maintains the battery on trickle charge. Fast delivery

My BMW R1300 GS came with a lithum-ion battery and its doing its thing, longevity wise time will tell as this is the first time I've purcahsed a Optimate charger.

My Oxford Oximiser 3X has been working flawlessly since 2018, bought this Optimate charger as I couldn't use with the Oxford one with the lithum-ion battery & this charger is something that BMW themself advise on getting as well as multiple owners on various forums & youtube vlogs.

Physical set up was easy and there is ample cable length for a tidy underseat install. It comes with a J clip which can be used to hang it on the handlebar as well as mounting hole for the wall mount - I've mounted mine on the wall to ensure its stays steady in one place.

All connecting cables including the charger itself look and feel better in quality than my Oxford Oximiser 3X. However, at this price range it would have been nice to have a screen like the Oxford & other chargers have, showing the functioning mode, battery status/health and voltages etc. My £15 battery optimiser from Lidl that I use for cars has a screen showing all those functions etc - so Optimate if you are reading this - this is something to consider adding to future models :)

Giving it 4-start instead of 5 due its poor instructions in comparriosn to its competitors & not having a screen - had to watch youtube video for clearity on functions & features. This was to ensure right mode/function was selected for the lithum-ion battery. As there have been cases where wrong mode/functions has ruined lithum-ion batteries because supplied instructions aren't that clear to understand.

keeps my batteries in good condition throughout the winter, I definitely recommend it

No issues with ordering or delivery.
Put to use as soon as it arrived. A good bit of kit to keep your battery fully functional.

I have used Optimate for every bike and even when you haven’t been near the bike for months it will fire up first time. Highly recommended

Works very well, but the user interface and the instructions are arduous to understand, they would benefit from being simplified. The size of the overmoulding on battery terminals would benefit from being slimmed down, they became trapped between the battery and the battery box, making inserting / withdrawing the battery a little difficult.

Good quality,and very fast delivery.
