(40-255) CT5 Time to Go-12 Volt Battery Charger and Maintainer with Accessories

Great Battery charger/maintainer . Very easy to use and so far working as described .

As a maintainer to a automotive battery it did what was needed and expected. This one is 4 amps that is enough to compensate for most battery draws from the vehicle. Easy to install, easy to operate, durable and easily stowed away. Works on all types of batteries and comes with a quick disconnect when you want to put it away or use it. The display is useful in determining the condition of the battery and state of charge. Cord is long enough to be useful and they do offer an extension cord at an extra cost. The big European MFGs offer a similar if not the same branded charger for more money. Sometimes to the tune of 800.00 dollars more. Save your money and buy this one.

Excellent charger for my corvette in the winter months. Essentially plug and play. Pretty idiot proof. Display lights indicate.if something is wrong and the progress of the charge.

This is my second unit as they work really well. It is capable of many things and does a fine job keeping the collector car battery ready and in charging up the daily drivers that go short distances requiring the occasional "top off" type charge. Would by it again if needed. Plenty of clams and methods to connect to the battery too.

I had an inferior trickle charger for a couple of years, I did not trust that you could plug it in and walk away. It got so hot, I expected it to eventually start a fire. I bought this CTEK and after the first recharge of a dead battery, I new I made a good purchase. It cost about twice as much, but when you expect the battery to be charged it's charged. The lights on this let you know where its at during charging and if there is a problem. The unit is pretty small compared to the one it replaced, but it recharged the battery in half the time. During recharge and maintaining it never got hot. Money well spent on CTEK. I will be buying another one in the near future for my jeep too. You won't be disappointed if you spend your money on this.

This is a nice little charger that is supposedly the original manufacturer, just not branded with BMW, which is totally OK, as long as it works. I didn't have any problems with it per se, but it's not great at predicting, how long it will take to charge the battery. Either that, or it's not accurate in estimating the amount of charge currently in the battery. Having said that, it is still safe to use and it does its job eventually.

Just set it and forget it. I works great. No risk of sparks and brings life to older batteries and makes sure newer batteries maintain longer.

Product met my expectations

Es un buen producto, que sirve para mantener siempre cargadas las baterías de los vehiculos

I have had this for about 18 months now, and use it to keep my John Deere mower battery charged. It’s small, and can be mounted on a wall. The clips for the battery + and - are plastic covered and easy to use, and stay in place.

Very easy to use. Either the bonus if knowing when you can use the battery 🔋. Good quality build and comes with useful accessories. Highly recommend.

Compact, easy to read just an extension required to plug it in just like a block heater but with more, you can see the charge and it stops automatically once fully charged, there nothing more frustrating then a car that won't start, and lets face it our winters will never mild again with climate desaster reaching us. Good invesment so far.

CTEK products are always meet or exceed my expectations
