Most helpful customer reviews
82 of 82 people found the following review helpful.I own two of these excellent chargers - they are very simple to operate and very durable.The chargers are weatherproof, and you can permanently mount them in the engine compartment with the provided ring terminals, or just use the alligator clips.The charger has a battery status indicator (low / full), and settings for Motorcycle, Car, or Gel battery. The charger cycles from trickle current, to pulses, and shuts off when the battery is full. There is no better charger for winter storage battery tending, bringing nearly dead batteries back to life, or just recharging boat batteries slowly overnight.Finally, I should mention that the current version of the 3300 has some improvements over the already excellent older version (I now have one of each). The latest version includes:- Heavier gauge wiring- Much heavier and more durable alligator clips- A nice zip-up storage case
39 of 40 people found the following review helpful.This charger, as well as the current (more popular) Battery Tender chargers are both made in China. This charger seems to be superior to my Battery Tender chargers in that it appears to be well sealed, of a more modern design, spark proof. Enclosed in a two piece cast housing, not an aluminum box. The charging algorithms will bring back a sulphated battery in some cases. It has three different charging settings, and brought my sulphated APC UPS battery back to limited life. It is particularly well suited for small motorcycle size batteries as well as larger batteries. It may be left connected indefinitely..My only complaint is the cheap power cord that gets as stiff as a broomstick in extreme cold. . . . . $%##@!! cheap plastic covered power cords, anyway!
25 of 25 people found the following review helpful.I ordered 2 different chargers to maintain my gate opener's deep cycle battery (a simple 4 output charger with extension cords for charging other deep cycle batteries from amazon Battery Tender 022-0148-DL-WH 12V 4-Bank Battery Management System) and this unit has a far superior charging design.The 4 bank battery tender does a simple fast rate charge then switches to a trickle charge at a constant voltage with 4 outputs.This unit pulses the battery under charge and features 3 operating modes with different current outputs for different sized batteries. The selections are motorcycle which also works well for SLA gel cells or AGM batteries, standard automotive starting battery, deep cycle batttery, and off.What makes the CTEK unit special is that it uses a pulse charge in all modes to attempt to desulphate batteries, while the battery tender does not. This method of charging has proven successful in restoring lead acid batteries that won't take a charge any more.It comes with a waterproof 12V output cable and a set of clips or rings for permanent installation under the hood of your car. In addition to the LEDs for indicating the type of battery being charged, a second set is provided for empty, 1/2 full, and maintenance pulse charge mode.There is also a noticable increase in quality between the battery tender and this unit - small details like a water sealed housing and gaskets on the connectors indicate quality in manufacture.For a single 12V lead chemistry battery this is a useful, well made tool.
