What customers say about "Key Specs"
CTEK Multi US 7002 12-Volt Battery Charger
  • This saved me several hundred dollars for a replacement battery. I just bought a second unit for my Porsche.
  • This is a must have charger, reconditioner for anyone who has expensive AGM, SLA batteries. Simple plug and play use.
  • 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.
  • It is not a heavy duty jump starter for a very dead battery.
  • The unit senses the condition of the battery and follows a programmed charging pattern. It's truly set-and-forget. If the battery connections are crossed, the unit will not activate.
CTEK Multi US 25000 Fully Automatic Battery Charger
  • I have got to tell you this has got to be the very best battery charger I have ever used ever. I had a battery that with a normal charger would not not and this charger saved it.
  • To sum it up in one word - its a very fast charger, and safe at the same time - NOTHING like the old crank up the timer based on the voltmeter chargers.
  • This was a present for my husband.He did extensive research and decided on this one. The battery charger helped safe money by "reconditioning" several batteries that would have been junk. Great battery charger and works as advertised.
  • Amazing battery reconditioning system, and also if course charges the battery. In my case saved my car existing battery from replacement.
  • Broke less than 2 months. Dont buy, if u need to buy one, buy from ctek directly.

What customers say about "Size & Weight"
CTEK Multi US 7002 12-Volt Battery Charger
  • Light weight, small, portable, ez to use. simple to understand the little colored lights!
  • I like the small light weight form factor and with the output extension cable I am able to hook up the vehicles while parked in the driveway and keep the charger in the garage out of the weather.
  • So far the CTEK Multi US 7002 12 V is a success well worth the money. An additional plus is its small size and low weight.
  • It does feel rugged but it seems to work very well...easy to carry light weight with intelligent electronics.
  • This small, light weight charger does the trick. I can leave it plugged in under the hood until I need to use the car and it does it perfectly.
CTEK Multi US 25000 Fully Automatic Battery Charger
  • Really quiet, the size is really small compered to other chargers. I would recommend this charger to anybody.
  • So far all I've done is try to revive a junk battery which was beyond Salvage. It does seem to be a very nice unit and compact for its power size.
  • Nice, reasonably compact for the power it generates.

What customers say about "Features"
CTEK Multi US 7002 12-Volt Battery Charger
  • All great and as advertised. Unparalleled features. Adapters and accessories to use any way you need to.
  • The restore feature is the best and most unique feature of this charger. It will bring batteries back form the dead (if you are patient).
  • This has LED indicator lights which is a nice extra feature when the charger is not hooked up to let you know the condition of your battery.
  • The only feature I wish it had was a "boost" feature. But any charger with a useful boost feature of any use has to be a really large one so it would be impossible to fit that feature in this form factor.
  • The recondition mode on the 7002 is a great feature. These chargers are well constructed and weather-proof.
CTEK Multi US 25000 Fully Automatic Battery Charger
  • Unlike the 7000 series (7A), the 25000 (25A) series has an internal ducted cooling fan which only comes on during high current charging for long life.
  • It has the desulphation mode like the other chargers, but can handle larger cells. Other than that it does NOT have the ability to select SLA (gel cells), wet cells, or marine cells
  • There are 3 wires at the end of the fixed cable (which does not work with their accessory system as it does not have the required connector) - the 3rd wire is a temperature sensor designed to be held close to the battery during charge.
  • The first Multi US 25000 I received appeared to work normally, but the "T" LED remained illuminated. According to the owner's manual and CTEK USA's web site, this indicates a problem with the temperature sensor and/or sensor wiring.
  • My charger stopped working on the third time of use n indicators keep flashing in a circle like pattern going around n around. No trouble shooting guide that outlines this problem. Hoping to get some feed back from CTEK customer support.
