Questions and Answers for UPG 12-Volt 250 Ah L4 Terminal Sealed Lead Acid (SLA) AGM Rechargeable Battery

A:  Made in China or Vietnam

A:  Made in China or Vietnam

A:  As of right now we have them in stock.

A:  It is but it is the size of a garden tractor battery to get the Amp hours of a group 24 battery you would need 2 of these and to get it close to a group 31 battery you would need 3 as these are only 35 Ah each.

A:  Yes often used in mobility scooters. 12v batteries full discharge is at 10.5 volts and best practices are discharges of 50% and above meaning 12.3 volts is about as far as you would want to discharge it. All deep cycle SLA batteries wear out faster with greater depthe of discharge.

A:  A UB-8D is actually a 250 Ah, a UB-4D is a 200 Ah.

A:  YES AGM settings on controller and each 35 Ah battery can handle 100 to about 120 watts of solar panel each.

A:  Yes it can and this is a 250 Ah battery. Controller would need AGM settings and 75 amp or less output PER battery at 12v.

A:  That is a large trolling motor. In a small 1 man kayak with a small trolling motor the ub12350 would work however for this sized trolling motor you would need 2 100+ Ah batteries like a ub121000s or larger.

A:  A U-1 sized battery is very small to try to run an electric go cart. This is the size of a wheel chair battery or a mid sized lawnmower starting battery. Most golf carts will be a group 27 or GC2 sized.

A:  It depends on what you want in terms of voltage and current. Here's a brief explanation: Connecting two 12 Volt 35 Ampere Hour batteries in series in the same manner as how batteries connect when put one behind the other in something like a two or more "D" cell Flashlight increases only the voltage. Not the current. In this particular case connecting two 12 volt 35 Ampere Hour batteries in series gives 24 volts at 35 Ampere hours. In the case of connecting batteries in series one could say the chain is only as strong as the weakest link in terms of current capacity. However connecting two 12 Volt 35 Ampere hour batteries in parallel increases the ampere hour rating yet does not increase the voltage. To go back to our chain analogy one is making the link that much stronger in terms of ability to provide current to an electrical load.

A:  Yes, it would just be a positive to positive connection. If you use larger batteries in a boat that are 70 Ah this can be a back saver if you remove the battery when done.
