3A Car Battery Charger and Maintainer, 3-in-1 Solution, for 12V Power Sport, Automotive, and Marine Batteries, SP1297

This works great. Maintains my golf cart battery perfectly. Schumacher is always good quality and the display makes it easy to use.

My John Deere lawn tractor sometimes sits long enough that the battery becomes weak enough that I have to jump start it. I just don't like having to use jumper cables, this charger/maintainer keeps the battery charged so I'm not bothered with jumper cables.

I'm a retired auto tech and have lots of experience with battery chargers. Just got this today to replace the Die Hard model # 71239 which is made by Schumacher and is identical to this SP1297 with the exception of this one being red and the Die Hard being black. Nice digital readout banner, walks you through hooking it up and getting it charging. Reads out the charge rate and once fully charged, the unit goes into automatic float mode and the unit's green indicator light slowly pulses on/off to indicate it's in "maintain mode" I had the Die Hard model for several years (bought it from Sears) and used it on a classic car that was mostly garaged. I gave the Die Hard charger to my daughter for use on a new Generator's battery to keep it fresh. I tried the NOCO genius 1 as a replacement but was not impressed and returned it. This Schumacher comes with accessory hookups ( Alligator clips, Hoop type attachments for permanent installations and a cigarette lighter style plug in adapter) It's great for light use and maintaining batteries. If you need to recharge a dead battery, this will do the job albeit slowly. At $40 this charger is a steal! I have another heavier duty charger (Stanley brand/also made by Schumacher) that is more powerful with more features. Schumacher makes the majority of battery chargers which are sold under different brand names. No surprise there as most electronics are rebranded with different colors and labels. I hope this review helps in making a decision regarding this charger.

Purchased this over a month ago. Have used it off and on in that time to keep motorcycle and other AGM batteries topped off for the season. This puts a top charge on (as expected) in a fraction of the time of my trickle chargers. It's so much easier than pulling out the big charger. The unit has a nice design and the hanging hook is very handy although it feels flimsy, it works fine. Like the digital display. There is no visual charge level status except at the very beginning to tell you the initial charge level in the battery. It would be nice to gauge how much longer the charge may take when checking on it. Not a deal breaker by any means. It does what it's suppose to; charges batteries well. Comes with many connection options in the box. All are great quality. This has become my #1 charger. Update after a year of ownership: This charger has an ongoing issue charging AGM batteries. Will only charge partially. Green light fading indicating full charge when Batt is only at 83%. Also has aborted charge for no reason on newer AGM. Have to unplug and restart to continue to get a full charge. Happens the same each time. Average use is once a week during the colder weather. It became nuisance having to check on it all the time because it has no state of charge indicator. Learned to work around the quirks for now. The scrolling marquis display is nice but seems more of a novelty. Having 4 batteries (2 AGM and 2 MC batts) to maintain, it can become time consuming waiting for it to cycle each time Except for these issues, it still works and gets the job done.

I really like the Schumacher battery chargers. I have two of them, one for each car. I hang them at the front of the garage in front of each car, and using an extension cord (https://www.amazon.com/SPARKING-Extension-Connect-Harness-Waterproof/dp/B0746DX2L1?pd_rd_w=dlDwu&content-id=amzn1.sym.cfc0e7a6-c58f-4345-944f-e34fcbad5a71&pf_rd_p=cfc0e7a6-c58f-4345-944f-e34fcbad5a71&pf_rd_r=YQ0MJXMYECM9PMQERGE6&pd_rd_wg=ykNhG&pd_rd_r=8fad6d97-1669-46b4-a18f-8a8202df93ee&pd_rd_i=B0746DX2L1&psc=1&ref_=pd_bap_d_grid_rp_hxwhrp_sspa_dk_bia_0_1_ec_t) to connect to the cars to keep the charger off the floor and out of the way. I connect the chargers to the cars using the provided quick connectors that you attach to the battery (actually attaching the negative to another part of the car), then it’s just a matter of mating the plug from the connector to the plug on the charger. The charger first analyzes the battery. If the battery is bad, it’ll tell you that. Otherwise, it gives you the charge level of the battery and begins charging. When fully charged, the charger switches automatically to maintenance mode so as not to overcharge. Both my cars have the higher powered lead acid absorbent glass mat (AGM) batteries, for which this charger is appropriate. AGMs are necessary if your car has the auto off feature when you come to a stop, automatically shutting off your engine then starting back up when you release the brake pedal. Since the AGMs are substantially more expensive, I connect my cars to the chargers almost nightly as today’s cars have a LOT of electrical stuff going on even when the engine isn’t running. This contributes to a shorter battery life, so I figure it’s worth the cost of the charger to extend the battery life. My first AGM lasted 10 years, fwiw. Regardless of your type of battery, I highly recommend using a battery charger for your car even if it’s driven daily, and I highly recommend Schumacher chargers.

I like it, plug it in, set the battery type then forget it for overnight- days - weeks- however long, it adjusts itself as needed.

Waiting very long for my refund money !!!!!!

This is my 3rd unit. I use them on 3 vehicles in storage, on Winnebago, BMW Z4, bmw 128i. So easy to set up and the digital display is what I like. No guessing. Display gives status.

When i received it doesn't work.

Schumacher encontró el punto de equilibrio ideal para cargar la batería con 3 amperes yo he usado este tipo de cargadores cuando eran de 1.5 y 2 amperes pero este los supera ampliamente

Easy to use
