User questions & answers

Question:	Why is it not recommended to keep a trickle charger hooked up all the time
Answer:	beats me. i keep mine hooked up from 12/31 to 4/1 and only then do i take it off. my understanding is that you do not need to disconnect it-it powers down on its own, but you mught want to find the user nistructions and check me on that. good product if youre not in a hurry
Question:	how fast does it work
Answer:	if your battery is low it may take up to 3 0r 4 days since it's a low amp charge and designed to keep the battery at full charge once it's at full charge. This charger is super for use when you don't drive the vehicle a lot and it sits for any length. it can be used on the battery in the car or taken out, once it's on it can stay plugged in all winter of summer just unplug it when you go driving. If the car stays outside they make a waterproof model. If your looking for a fast charger this is not what you want, if you do buy this make sure it's the 12 volt model ... hope this will help you
Question:	Why is this not available in California
Answer:	Charge for free! Buy a low wattage solar battery charger/maintainer at Harbor Freight instead because it works very well maintaining the battery charge provided that the battery is fully charged before hooking up this solar charger.... it will only maintain the charge. Not made to fully charge a discharged battery. Point the solar panel southwest to get the most out of the sunlight during daytime. I have used this $9.99 if on sale gadget for years now on my boat and car and has not failed me yet. It comes with all the hook up accessories needed. I have not used the boat for 2.5 years at a time and the gel battery is as good as when I installed it 7 years ago. My car wet cell battery also is as good as when I first installed it and I only use the car abroad every 12 months when I am in town for 3 weeks. Car or Boat batteries Gel or not will not last it's lifetime if it is always discharged and recharged. Maintaining the charge is key to it's longevity. Good luck! No need to blame anybody. The State of California is an environmentally conscious state and that is a good thing for everybody.
Question:	Can this be used to charge an AGM battery
Answer:	Stupid me, but don't all lead acid batteries use the same chemistry? I've read only that 6-cell lead-acid batteries should never use a charging voltage exceeding 14.4 volts, since water will begin to H2 gas and O2 gas above that. You risk explosion and loss of electrolyte beyond that. Explain why this is different for AGM, Flooded, and Gel batteries!

User questions & answers

Question:	Will this work on a dead duralast gold battery
Answer:	Right angle plug, but no issues connecting to any radio so far.
Question:	Is it portable or it have to be plug in all the time
Answer:	This is an 8 ohm speaker, not 4 ohm so if your application needs a 4 ohm speaker (most car sound systems are 4 ohm) and you use this one, it will not be as loud as it should be. I used this speaker for a Motorola 2 way radio in one of our fire trucks that had a bad internal speaker and so far it works AWESOME and is plenty loud and clear even at half volume.
Question:	Can you use it on two deep cycle batteries hooked in parallel
Answer:	I do not believe there is a warranty but I can tell you it is a great speaker. The speaker is used with my Yaesu FT 8800R and I would recomend it.
Question:	I recently purchased this battery charger but I received a Stanley brand. Did anyone actually receive what is pictured (Black & Decker
Answer:	no i t does not we can see were we are all over long island sound and Ct river in old saybrook ct.

User questions & answers

Question:	Which model is a maintainer and jump starter
Answer:	G15000 and G26000 both are a maintainer and Jump Starter. I verified. but you need to wait 5 minutes to JUMP START a DEAD battery vehicle. Beware, YOU CAN ONLY insert the power plug into the wall power outlet AFTER you connect the battery. When you are connected, then insert the power plug and then, PRESS the JUMP CHARGE and WAIT for 5 minutes. YOU WILL BE impressed after 5 minutes.
Question:	will it jump the engine
Answer:	Yes. It can. I verified this function. It's called 5 minutes' JUMP CHARGE. but always remember, Insert the power plug ONLY AFTER you connect the battery. when you are done connecting the + and - terminal of the battery, THEN you can insert the power plug into the wall power outlet. It will take 5 minutes to charge the DEAD battery from Zero back to LIVE enough to JUMP-START your vehicle. I approved this message. It works!
Question:	The descripition says it can jump start. Has anyone used that feature
Answer:	The G15000 features a 5 minute, 20A Jump Charge mode that can be used to rapidly increase the voltage on a heavily discharged battery. It jump starts all kinds of 12V vehicles though the process may need to be repeated two to three times for larger vehicles.
Question:	Is this actually made in the usa or assembled in the usa or made in china
Answer:	Too late I'm sure, but maybe someone else will benefit - it doesn't have a battery, you can't "charge the charger". Mains powered only. Lol. Item itself is not labeled as to location of manufacture. Purchased December 2020. As of February 2021 it's discontinued.

7-STAGE CHARGING AND MAINTENANCE MODES

1. Desulphation: Pulse charges the battery to break down the build-up of lead sulphate crystals. Lead sulphate crystals can occur when a battery has been discharged or left unused for a period of time, seriously affecting the performance and lifespan of the battery.

2. Soft Start: A slow steady buildup of the charging process that limits the power supplied to protect the battery.

3. Bulk Charge: The main part of the charging process where 80% of the charge is applied.

4. Absorption: Fully charges the battery by slowly reducing the charge rate to allow the battery to absorb more power.

5. Battery Test: An automatic test to determine the battery condition after charging. If further charging is required, the Recondition stage is selected. If fully charged, the battery goes into Float status.

6. Recondition: Unique charge state to recover deeply discharged batteries.

7. Float: Maintains the battery at 100% charge without overcharging or damaging the battery, allowing the Smart Charger to be left connected to the battery indefinitely.

User questions & answers

Question:	This optima charger how long is the warranty, thanks
Answer:	The length of warranty on paper doesn’t matter because getting them to act on it is difficult. They wanted me to send the charger to them at my cost and wait without a charger for 6?weeks
Question:	Are the battery terminal clips/clamps plastic
Answer:	Yes, they are plastic. And Yes the break. My negative terminal just snapped in half... Not happy. Why couldn’t they just use metal??
Question:	Does it work with Optima battery only or work with all brands
Answer:	It will work with any brand of battery.
Question:	Are the clamps made of plastic or are they built of some other material that will actually last
Answer:	The clamps are metal on the inside (obviously), and a durable plastic on the outside as insulating covers. Looks to be pretty durable, I've had no problems with them. But then, I tend to take care of my toys! :-) This unit, by the way, was an excellent investment...after having owned several less-capable chargers. This one restored my Yellow Top battery back to its full capacity in short order! I own a Tahoe Hybrid and had installed the Yellow Top as a result of standard batteries not holding a full charge after a year or two, and often draining when not running the Tahoe at least once every 4-5 days or so. Can connect full-time to the battery the accompanying cable, making the use of clamps unnecessary! Just have to remember to unplug it!
