Review: CTEK 0.8 - This is CTEK's smaller charger for charging 12V batteries from 1.2Ah to 32 Ah and maintaining batteries up to 100Ah. This is a true smart charger with "six" stages. Truth be known, it's really three but I'll say that the others are nice to have. It's a sealed unit about 8" end to end including the strain releif on the permantly affixed leads. If features mounting holes on the main body which are nice (fitting #8 machine screws, 10's might fit.) The unit gets warm, not overly hot, but noticably warm. If this unit is perminantly mounted as in my case, use nylon spacers behind to give it a little air between the unit and the wall. I think the back is the warmest part of the unit. Despite being sealed (and assumed by many to be weather proof) the instructions clearly say this unit is not be used in the elements. It has a sturdy two prong cord that might be a bit short for many applications but a 16ga extension cord should be safe to use as long as all other safe considerations are made. It ships with two types of leads (both fused with ATC style fuses). An aligator style clip with large jaws suitable for full sized car batteries. It also ships with 1/4" ring terminals that can be quick detached from the charger without disconnecting from the battery terminals. What is a "smart charger"? Simply put its a chager that regulates the voltage going to a battery to prevent over charging it and most then "float" when they determine the battery has reached a full charge. 20 years ago most chargers needed to be monitored. Nowadays most small electronics have over charge circutry built in (i.e - cell phones, laptops, ect.) But for some reason, some 12V chargers are still using a steady voltage source to charge batteries. Over an extended period it will literally "Cook" the battery. Not all smart chargers are made equal either. Some have a bulk charge that brings the voltage to 14.4V for a time then "floats" the battery at a lesser voltage for extended periods of storage. CTEK has included programing that periodically analyzes the battery and mades a decision on whether it needs to continue floating or actually transition back to a heavier charge stage. Unlike chargers for smaller batteries and lithium batteries this charger does not require nor have the ability to enter the Ah capacity into the charger. Instead like most"car" battery chargers it relies strickly on voltage which as long as your charging Lead-acid type batteries is fine. The stages are... 1) Desulfation - removes build-up on lead plates inside the battery. 2) Bulk Charge - Brings the battery voltage up to 14.4V and about 80% of maximum capacity. 3) Absorption - Continues the charge with steadily declining current while still holding the voltage at close to 14.4. 4) Analyse - Stops charging and sees if battery voltage free-falls (happens if battery has reached the end of its life cycle.) 5) Float - Applies roughly 13.2V at a small current to maintain the battery voltage. 6) Pulse - Not entirely sure but sounds a lot like float, it switches off and on rather rapidly to maintain maximum charge. According to the literature batteries may take as much as 1 hour per Ah to reach 80%. After 80% times are hard to find but it sounds like this is also where you can maintain larger capacity batteries (32-100Ah.) For my use, I'm charging a 22Ah sealed lead acid battery as part of a power supply for a DC powered electronics project. So far it's doing well. But this charger would certainly be suitable for small motorcycles, lawn tractors, and generators with electric start. As a maintainer, for larger batteries I'm less entusiastic about it. I would spend a little more money and move up to the CTEK 4.3 or the 7002. The 32Ah limit on bulk charging makes this somewhat less attractive for owners of boats, RVs, and garage kept cars. As long as the battery is fully charge when stored it works but especailly with boats that may not always be the case. Still the "0.8" is leaps and bounds ahead of its competition and only about $10 more expensive. Just make sure to follow the safety practices listed and always inspect your batteries regularly. Also, this may boil water off a NON-maintenance free battery so be aware of that if thats what your application uses. This paragraph is specific to my application but I went ahead an included it as it might give others some insight. So that I might get more detailed information I allowed the 22Ah SLA battery to discharge (disconnected the charger) under normal usage. It averaged about 60mA of current draw from the battery for about 36 hours. The starting voltage at the beginning on the discharge was 13.3V and the ending was just under 12.9V. Once the charger was reconnected quickly moved to stage 2 and started the charge around 13.2V @ 900mA. This trailed off within a few minutes to 13.6V @ 850mA. After a half hour, still on stage 2 it was pushing 13.8V @ 800mA. Through all of this the load was still connected drawing roughly 36mA. At an hour it was still stage 2 with 13.9V @ 790mA. In fact the amp charge held 790 until it passed a charge voltage of 14.2. Up until that point the battery had been taking the steady 790mA and adding 1mV about every ten seconds. Passing 14.2V however the amperage began to trail off the voltage increase slowed as well. At that point it was nearing the end of the stage 2 cycle. Still it took another hour to complete dropping to about 560mA of current and peaking at 14.27V. Total time spent on the bulk cahrge was 2hrs 45mins. As stage 3 began the voltage inceased slightly to about 14.28V but the amperage steadily but slowly deceased. 15 mins after beginning stage 3 the amerage was down another 50mA to 510. After an hour the amperage had dropped to 430mA and the voltage had climbed just shy of 14.29V. After 3 hours into stage 3 the power moving into the battery was 14.30V @ just below 360mA. By 4.5hrs the voltage was holding steady at 14.30V and amperage was down maginally to 345mA. The CTEK transitioned to stage 5 (float mode) after about 4hrs 45mins on stage 3 and about 7.5hrs total. That battery began discharging due to the DC load I had connected. The voltage began steadily dropping for about 25 mins then when reaching the target float voltage and while still on stage 5 the readings began fluctuating about every two seconds. The battery would discharge for a half second then recieve a charge of about 60mA for 1 sec. This has continued to repeat. While in the stage 5 float mode the battery charger is much cooler. Only lightly warm to the touch. When I changed the load from "standy" to in use the float applied a steady current of 40 to 50mA to offset the 100mA to 120mA of draw. The battery voltage dropped about 1mV every two mins. However with the load returned to the standby mode the float current once again stablized and retuned to its pulsing fluctuation. So in summery this will float a battery with less and 45mA of draw on it (clocks, ect) and can always revert back to a full charge if that proves to be insufficent.
Review: Quality battery charger for motorcycles and lawn equipment. - This is my second charger. The first lasted for nearly 7 years. This is not a fast charger. It seems to check your battery status and then slowly charge in steps. It does work well with motorcycles and smaller batteries, but your battery must be in decent shape. it can only do so much for dodgy batteries. It has the specific connector I need for my lawn tractor and motorcycle. It is not very large, so you must be careful not to step or drop anything on it.

## Questions & Answers

**Q: Does this model come with the correct connect for Husqvarna lawn tractor with charger plug in by battery  indicator?**
A: I reseached this question and to the best of my ability it appears yes it is.

**Q: Do the ctek cables use sae connections or are they unique to ctek??**
A: Our Comfort Connect System is unique to CTEK. We do offer an SAE connector that is compatible with many of our chargers 
(part# 56-564).

**Q: Will this device perform well for batteries found in cars?  this page says "for charging batteries in motorcycles, jet skis, atvs and lawnmowers."**
A: The US 0.8 is designed for charging 12V lead-acid batteries up to 32Ah which are typical size batteries in motorcycles, jet skis, atvs and lawnmowers. It is not designed for charging larger car-size 12V batteries.

**Q: How long does it usually take to charge a car battery?**
A: It depends on the state of charge.  The CTEK US 0.8 would take a very long time to do a weak car battery.   Could be 12+ hours.  But  OK for maintaining a fully charged battery.   I have one but use it on a small battery for an emergency generator.  Perfectly fine for that and similar smaller batteries like a motorcycle.  While I would certainly recommend CTEK (I have 6, 3 different models), I would consider a more robust version for a car if charging time is a concern.

### ⭐⭐⭐⭐⭐ I've ended up with four CTEK's. I'm very happy my little charger army. It takes a little thinking to make your best choice.
*by A***Y on January 28, 2018*

I've ended up with four CTEK's. Batteries are expensive, and after much research, I've found that CTEK is the one to get, to protect that investment. Other chargers can damage batteries if left on too long. See Jay Leno's videos explaining this. CTEK (56-353) MULTI US 7002 12-Volt Battery ($117) of the four CTEK's that I own, this is my favorite, because it has all the features of the CTEK (56-353) MULTI US 7002, with more power capability. The CTEK 56-864 Mus 4.3 12 Volt Fully Automatic ($60) is a nice alternative if lower cost is required. (see below) CTEK 56-864 Mus 4.3 12 Volt Fully Automatic ($60) of the four CTEK's that I have, this is my favorite below $100. The "mode select" and multi-LED's are nice, and it indicates desulfer, and recondition modes. CTEK (56-158) MULTI US 3300 12 Volt Fully Automatic 4 Step Battery Charger ($65) - This one gave me "buyers remorse". For $5 less, I prefer the CTEK 56-864 Mus 4.3 mentioned above. The fewer LED indicators on the 56-158 leave something to be desired for information, as compared to the other CTEK's models. It also does not have an LED to indicate "recondition" mode, but the manufacturers information says that it does it automatically. CTEK (56-865) US 0.8 12 Volt Fully Automatic 6 Step Battery Charger ($45) This one is a nice less expensive choice as a CTEK for "healthy trickle charging maintenance", but the lack of extra features would lead me to choose the CTEK 56-864 Mus 4.3 12 Volt Fully Automatic ($60), or the CTEK (56-353) MULTI US 7002 12-Volt Battery ($117) if I would only have one. The CTEK (56-959) MUS 4.3 TEST&CHARGE 12 Volt Fully Automatic Charger and Tester ($87), would be a nice choice if you do not have other testing equipment, but I am handy with other equipment for "testing" so I'll probably never get this one. Be careful to not be rough with the alligator clips, because the plastic is brittle and breaks easily. Once the plastic insulator breaks off, you then have an exposed metal clamp. Also, if you get one of the high power units, and also a low power unit, the leads are interchangeable, but the smaller unit will have a smaller in-line fuse that can "blow" if it is used with the higher power unit. Original writeup>Very nice unit. Very well designed. Very healthy for batteries. Avoid the cheaper "knockoffs" under other name-brands. This particular CTEK model does not have a "recondition" mode to improve battery life like some of their other models, but is does have a "safe for your battery" trickle charge function designed in so it is good to maintain stored equipment. Most other chargers can damage batteries if left connected for long period maintenance. Jay Leno has published YouTube Videos explaining how other chargers were allowing batteries in his fleet to fail early, and he switched to CTEK. It is not a heavy duty jump starter for a very dead battery. Research the different CTEK models to see which one fits your needs. I work with electricity / electronics, and CTEK's design makes good technological sense. I've purchased 4 of their models for different size batteries, and I've given some as gifts to my Dad's fleet : ) . He is also very impressed. You will be happy to know that you have treated yourself and your equipment to a very high-end product.
