How long can this battery run I have a wheelchair at 350 Watts and needs 2 batteries? And if a battery writes 31 A.H @20 Hrs is it 35 or 55ah?Thanks

Hi-A 55 amp/hr battery is approx 50% more capacity that a 35 amp/hr. If the higher capacity batteries will fit, go for the more powerful battery. The price is right! Craig

The need for distance should have been the question not amp hours. It stands to reason that for wattage 55 amps are longer lasting for most any chairs needs. Is your unit able to accommodate the size of the 55's if so that is the way to go. You will be happier in the long run...

I used a standard car battrery and it ran a radio 2 40 watt lamps for days before needing a charge. Make sure you dont get poitive and negitive mixed up. It killed my inverter dead.

It draws 90 watts and that comes out to 7.2 amps if your battery is at 12.5 volts. Use the formula VoltsxAmps=Watts

I'm pretty sure that these are considerably smaller. I'm pretty sure that what you have are 35amphour batteries and these are 12amphour batteries. (Amphour is a measure of capacity that means it can supply X number of amps for an hour.) I believe what you are looking for is a UB12350 battery although I'm not famailiar with your particular unit. Try looking at these and check dimensions. http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords;=12V%3B%2035%20AH%3B%20UB12350 I'm pretty sure that these are considerably smaller.

I believe it is a sealed battery, because I bought two of them to use in a motorized wheelchair. In that use, access to the batteries is a pain, so once I installed them, I forgot about them. Hope this helps.

I use it on a electric walking golf cart. Runs for two rounds without recharging. It is actually a wheelchair battery. Don't know about a trolling motor, seems like a lot more power requirement

This is a rough guess but, 6x35ah is 210 total Ah, and if you have 100w panel/ 12v it's about ~8 amp max. But I find mine realistically charges about 5 amp hrs per hr. So 210ah/5amp is 42hrs of charge time. so you prob have 7-9 hrs in day of good charge, so 42/~8 is at minimal 4 panels... I live in midwest and have less sunlight per day. But I think 4 is about minimal. I work more with electrical consumption than I do with battery charging so someone else might have better charging math, but I am familiar with electrical systems. Hope this helps and sorry for all the math, just wanted to back my answer. Good luck. This is a rough guess but, 6x35ah is 210 total Ah, and if you have 100w panel/ 12v it's about ~8 amp max.

Not sure how you plan on using them, but you need to know your wattage needs. these battery's are rated 3.7V 5000mAh (5 amps for 1 hour) So 2.5 Amp for 2 hours, 1.25 Amps for 4 Hours, etc...

Mine replaced a 12 18amp hour battery...works well. Mine is in a formula race car, so It's not driven every day like a motorcycle or ATV. I bought mostly for the weight savings, but it's a great little battery. Hope this helps

Hi, Thanks for your contacting. This battery is 44Wh. Hope it can help you. Best Regards, Amy CRTECH

its abt 8" along and 3-4 inches high and 3 inches acrossits a good battery to buy. i use mine for running abnd recharging my 12v tv and radio and such it drains pretty quick when used w/ a power inverter. but would be great for wheelchair

I have only chagred 1900mAh NiMH AA and AAA batteries, 8, 4 or 2 at a time. Can't say for 3500mAh though, should work as others have said once it's a NIMH batt.

If by 4a you mean 4 amp current draw then this 12 amp hour battery could run in for a max of 3 hours. About half that would be more realistic unless the power draw was less with lowered sound levels giving reduced amp needs. I run a ham radio transceiver with mine which pulls about 1.5 amps on listen and 10-12 on transmit. I have used it for over 2 hours of mixed use and it was still going.

This battery is rated at 2.6Ah. Mike V has already given a comprehensive reply. Ajax

The total wattage for 35ah is 35x12=420That is if you run the battery completely down making it useless. Average usage would be 50% down to 210 watts at the lowest draw done of 80% or 336 watts. Always remember AGM batteries take a long time to recharge. Using 210 watts average draw done you could use several items for that amount for about one hour if the are DC devices. If you use AC devices and a inverter you will lose aprox 20% of the wattage at the onset.

You COULD use the 55 amp-hour batteries, but you will lose some "endurance" for your power chair. Amperage, and amp-hour ratings are a measurement of energy available, and how long that energy is available. It would be best to stick with a battery that has the same rating as the original battery that came with your chair. Amazon has 75 amp-hour batteries. The case size for these batteries is the same as the 55 amp-hour battery. Check them out on this page,..just click on the link i included below. http://www.amazon.com/UPG-UB12750-Sealed-Battery-Electronics/dp/B000RZG444/ref=sr_1_fkmr2_3?ie=UTF8&qid=1361148970&sr=8-3-fkmr2&keywords=12V+75Ah+Sealed+AGM+Battery+Group+22NF It's good to know that all the training i received in electronics is still good for something :o) I hope this helps.

The battery is a 6fm-18, listed on the battery as a 12v-18ah/20HR. I'm not sure of the formula to convert the amp hours to watt hours.
