I'm looking for a rechargable battery pack for my boat electronics. Does anyone know if I could recharge these directly off my engine alternator? Tks!

Dear Friend: I've bought hundreds of those batteries for our enmotion paper towel dispenser. Also, I bought the charger for eight units of these batteries. They work very well, and we save ( in our job) a lot money, because in the past we've used the regular alkaline batteries, with a expensive result. I tell you, buy them and save money

The boat I use has a 12 volt battery, the outboard motor has an alternator that keeps it charged.

Yes , spare batteries are easily available through amazon. I have three for my boats.

Eric - you would only use 3 of the terminals.One terminal receives the power from the alternator and two others feed the batteries.This system works well on my boat.One terminal feeds my starting battery and the other feeds the battery for all the instrumentation.

You can charge a marine battery if you take it out of the boat and charge on shore. DO NOT charge a battery in a boat with anything but a marine rated battery charger. Anything from VERY rapid corrosion of your outdrive to your boat exploding could result. People that don't understand marine technical issues shouldn't attempt to answer questions like this.

A couple of things to know about these type of batteries. One never let them sit for long periods of allowing them to discharge below 10.5 volts. They will not recover. I have a battery tender in my boat which regulates these batteries at full charge at all times. Second your charger should have a AGM setting. You can find what you need on optima's web site. http://www.optimabatteries.com

yes that is what I do in my boat for 2 rv batteries and it works great. make sure and get the power regulator so you don't over charge your batteries.

I just picked up a battery at my local fleet farm. The key is to ensure that you get a marine battery since it is going to be subjected to constant trickle charging and full discharge situations. Typically any marine battery will work as the system only needs 12volts to run on. They had a "Resolute MDC24" marine battery on sale, that stated you might be able to find one cheaper through Amazon Prime.

Bruce get you a better game camera battery for your depth finder. That's what I use on my inshore kayak. This batter was a junk. Leaked acid when arrived in mail. I gave it a bad review and took it to a battery recycler. My loss for going cheap and I paid for it. Hope this helps.

I bought a 12 volt battery for an atv/motorcycle. I bought two small alligator clips( red and black) and attached them to the ends of the wire. Then just clip red to + terminal and black to - terminal. I don't submerge mine in the water so I had to adapt an intake hose. You'll need to suck on the output hose until the water gets through the pump. You'll need a small 12 volt charger for your battery. Not expensive, think mine was about $17. Hooking it up to computer power supply is probably not the best idea.

I added a second battery, it is simple and adds needed security when out on your boat if one battery goes low, also I used old car battery cables from the salvage yard, much cheaper, just get your lengths measured first....

i don't have the unit or manual immediately available but it certainly will not damage the batteries as the batteries are not charged by the adapter...the aa batteries are a completely separate system. the internal rechargeable battery should not be damaged either as that is a normal output for a charger. HOWEVER, i would suggest that you look up this unit's manual on the web before purchase and download it to be sure (virtually every manual known to man is there somewhere!) -- i honestly don't remember what the recommended output is for the charger for this unit. if i am back at my boat soon i will look at my manual to be sure and update this response if i am incorrect in my assumption. do check first! i don't have the unit or manual immediately available but it certainly will not damage the batteries as the batteries are not charged by the adapter...the aa batteries are a completely separate system. the internal rechargeable battery should not be damaged either as that is a normal output for a charger.

Barbara, not really sure. I have 2 batteries. I use it keep them topped off when the boat is not in use. It works well. they stay fully charged. I have left the live well running all night with the unit plugged in and it seem to keep the battery topped off. sorry I don't know more about it. I like the unit though.

The specs don't say but most of these Asian-made boats are using 4.8 or 7.2 Ni-MH battery packs. They should be available here or at any on-line or local hobby shop or battery dealer that stocks radio control proucts. Based on the battery pack in the picture, igt appears to be a 4-cell pack and that would make it 4.8 volts. Be cautioous when buying battery packs because manysellers are charging outrageous prices for NiMH batteries which normally are not terribly expensive. You should pay less than $10.00 for a 7.8-volt NiMH pack and a couple of dollars less for a 4.8-volt pack.

Hi Barbara, I contacted Wingscapes.com customer service about this and they replied that rechargable batteries are "not recommended." No further explanation was given. Have not tried it myself...but still would like to see if possible.

Yes you can. BUT!!! I would recommend an external power supply if you're talking about putting them in a computer. I know from professional experience that most computer power supplies don't have enough reserve output to handle that many properly. If one of them flickers or you unhook it and reconnect it while the computer is running, it will cause a hard reboot and you know that's how files get damaged. Hope that helps! A cheap battery charger is much better than using the computer power supply for multiple cold cathode kits. Stability is good... :):):) I also use a few of them for workbench and cabinet lights connected to a 12 volt battery with an automatic charger. Pretty sweet... In a car or boat you'd be good for probably however many you want!!! :):):)

Don't see why not - the boat battery is simply a power source. The device just draws what it needs, right? The connection is provided by the USB port.
