Question 1

Seller what is the power output of the 35amp hr battery ????

Accepted Answer

35 AH battery means that it can put out 1 amp for 35 hours. Power=current X voltage  so the 12 v battery produces 12W for 35 hours.
Resistance is measured in ohms, and current=voltage/resistance of load. So that battery connected across a 12ohm resistor puts out 1A= 12V/12ohms.
If you give it less resistance it will yield greater current so that you can get higher powers, but only for a lesser time. And unfortunately the ralationship in time is a losing proposition. You don't get as many amp hours at a higher current. At 10 Amps you might be lucky to get 2.5 hours. I used my batteries in a gokart where I had 2 12V batteries in parallel, made 2 more sets like this, put the.m in series, which yielded 36v at 20 amps for about 2.5 hours, long enough to bore the grandkids, and fully recharge the batteries after they went down to 12V (from their fully charged 12.8 to 13V)

Question 2

Would 4 of these batteries do well hook in series 48volts if they were powering a 1000watt brushless hub motar for an ebike ?? So confused please help

Accepted Answer

I did the research before realizing your question is over two years old and you're probably long gone but at any rate. Hooking 4 of these batteries in series will produce 48 volts as you'd expect, to supply the 1000w you're requesting these batteries will have to deliver 20.85amp, at this delivery speed they will deplete to 9.6volts in 60 minutes which effectively makes them 20ah vs the rated 35ah at 3.5amp. So I'd say they are not a good fit for the task because using them in this manner will give you about 225 charge cycles vs 1250 cycles if they were under a more reasonable task such as 3 or 4 amp load.

Question 3

I bought this battery....can it be charged with a black and decker 12v 25 amp smart charger?

Accepted Answer

Thank you for your inquiry. We recommend a 12v AGM charger with a charging output no higher than 10.5 amps. If you have any additional questions or need assistance, please do not hesitate in contacting us at 631-229-9361. We are happy to help!

Question 4

Can i charge the battery using 12v 0.5a charger? can i leave the charger on all the time?

Accepted Answer

I use a trickle charger on mine for long periods without any problems.
