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.

This product works like you'd expect. Simple and reliable. The only issue I have had is that it is designed to be used on an actual battery so the positive and negative clamps separate about 15". In newer cars that hide the battery away under a seat somewhere and have a positive terminal in the engine compartment, this can be a problem. I was not able to clamp the positive to the positive terminal and reach either the negative terminal or the frame with the negative (black) clamp. I ended up taking up the floor in my sprinter and accessed the battery directly. Then it worked fine.

I have several of these on all my vehicles and anything with a battery that you don't wont to have to replace next spring. I have them on my lawnmower, quads, motorcycles ect. This is the best trickle/maintainer I have found.

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.

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.
