@ supervstech - can you give me a better alternative to testing for voltage that you can help me fine-tune the issue, be it the battery or alternator? I want to determine if I have a possible issue and then take it for another opinion. But I want to be sure there is an issue--based on a better...

The voltage varies while driving. If the battery is pretty low like in the above mentioned posts, the battery monitor will show between 14.20 up to 14.55v. And as it gets charged, it slowly drops down to 13.4x, give or take. But that range depends on how long I drive or have the car on. I...

@ 400bird - I have a real volt meter, a digital multi meter by RadioShack (remember them?) catalog # 2200813. The car has been sitting since 5am today when I returned from. I went out w/ my multi meter to test the voltage. Current outside temperature is 55 deg. Its pretty cool out. Before...

@ tommthum62 - it is working now.

I don't understand how this is happening to me now. Well, this low battery issue started over this past summer. I have a tenant in my building who drives to work every day and his job is even closer, and he never has this problem. What am I missing ?

..Also, during this past summer, I took it to a local shop and then ran some quick tests on it and the alternator and they found no faults. When I showed them the battery monitor I was using to test and monitor the voltage, the mechanic said don't use those cheap things--they don't work! But I...

@ 400bird - so far the battery has never died on me. I know as I've been through it before. And in my experience, if the battery dies (I assume you mean, that a person leaves the headlights or fog lights on for instance, then the battery has died in those situations) the battery becomes that...

Hi to the Moderators -- FYI: I have not received any notifications for this topic that any multiple were made. I have a 2000 olds sih minivan. It is from Texas, I believe. I purchased it about 4 years ago, 178k miles, now 187.5k miles. I don't go very far with it. I was going to build it out...

Hi. I have a small problem with my car's battery not keeping its charge because I am not driving the car as much, plus, since my place of employment is closer to my house I only drive 1 mile each way. So, I am guessing that the car is not on long enough to keep the battery charged for long. I...

Is it possible to change the device name for the Bluetti EB3A. I'd like it to display something else, or nothing at all, if possible. TIA.

I am searching this forum and other sites for a battery monitor that includes the running and/or time remaining displayed whenever I add something to my lithium battery, like you get on power stations. I know I've seen this some years ago in someone's custom van tour where they had a small...

Does anyone have any experience with the "Pecron E600LFP Power Station 614Wh 1200W" system? I'd like to know the bad and good about it because I have decided to get one. Please share your thoughts and experiences with this system, thanks.

Correct.., portable solar generators. I was browsing around Amazon, looking at the many portables they have, and reading the specs. On some of the listings, I was getting confused with the runtimes posted for various common items such as lights, cellphones, laptops, etc.., and they appeared to...

I've been working on an updated run-time calculator and get different results, and I believe that I need to factor in the Wh also. But that may be for another story/topic. Anyway. I've seen battery watt-hours (Wh), (like 268, 360, 400, 517, 700 Wh's) with build-in 600-watt inverters. Using...

I do not understand this and I read how people return the SCC if it is a positive and not a negative. 1. What is the recommended setup, pos or neg? 2. What is the best or preferred one, pos or neg? 3. Which SCC are affected by this (requirement?) PWM or MPPT or Both? 4. How do I test/determine...
