Having had experience with and excellent impressions of CTEK Start/Stop for many years, I decided to go ahead and choose another model from the company for a lithium battery for a Tuono V4. This particular battery is a BSLi 04-06z. It doesn’t run flat, as it is a lithium battery, but I give it a refresh after four months of inactivity.

The high price of CTEK’s simplest charger made me look around, and I came across the NOCO 2. I went ahead and bought it, and my first impression is that it is excellent and very well built. I’ll report back in the long run.

I bought it to maintain two 12V batteries in a forklift vehicle. It is simple to use and effective.

excellent tool for charging car or motorcycle battery.
it saved me, I keep the scooter constantly charging because I don't use it often in the winter and its battery is always charged!!
it consumes almost no power, it's super!!

It is the best I have used. Especially for someone who wants battery maintenance for a long period of time. I have a GPS system on the bike that shows me the battery voltage in real time. It is the only charger that does not keep the battery at +13.5 volts permanently so that it is fully charged. What it does is let the battery rest and discharge down to 12.7 volts and then charges it again, and this repeats. Finally, after a power outage, it continues to operate normally without requiring a restart or re-selection of battery type (e.g. AGM).

Good charger. It doesn't resurrect the dead, of course, but it charges functional batteries decently.

I had three 12v 10.5 ah batteries. Two Yuasa and the other GK. I had an einhell charger from lidl. However, these three batteries were dead for about 2 years. Their voltage was about 1v. That's why I bought this charger. In the end, all three, while showing that they were charging for a whole day, finally lit up the option of short circuit - Not charging - consult a specialist.... Basically a product that I bought due to marketing and did not do what it said. However, in order not to draw conclusions only from these three batteries, in the coming days I will try two more dead batteries and reevaluate.
