You're being extra here. No way in hell I'm putting this much effort for something that cost me $100.
Agreed.

Disagree. In general, Li-Ion have higher energy density, that's why they are used in higher power applications. Lead acid would only have a higher capacity if they are substantially larger (which is why most are substantially larger.) "lithium ion achieves an energy density of 125-600+ Wh/L versus 50-90 Wh/L for lead acid batteries." - https://www.cummins.com/news/2019...technology

Disagree - Generally Li-Ion discharge 3-5% per month. Charging every 12 months or so is prob fine more than fine. (ideally not in the heat or cold) The manufacturer FAQ says 4-6 months - https://no.co/support/boost-faq​ [no.co]

Sure - but not practical to carry.. I think most people would leave them in the car regardless of battery composition.


Yes.. the downside of those is just size, but I agree it is nice to get the extra capability.


Maybe.. mine have been going longer and still good. The low self discharge rate of the Li-Ion batteries means even the first charge lasts a long and and they see very few charge cycles. I don't think most would consider 90% "dead", especially for Lithium-Ion. You could still jump most engines at 50% capacity... which I've done. In healthy batteries, a high output in AMPs (watts) can still be reached (e.g. to crank an engine) even when the power in VOLTS is moderate, which means it's still usable.

These should get charged very infrequently, so the life would be mainly affected by heat or cold, if people leave them in the vehicle.

Since Portable Lithium Jump Starter is mainly for emergency, do people store them in the car even during hot summer months?

And how long is the life of the internal battery for Portable Lithium Jump Starter that rarely use if at all (other than charging it every few months)? Do people replace it every 2-3 years?

1) Lithium is badly damaged in heat, especially the higher it's charged- You can read up on sites like Battery University, which have a few sections on Lithium batteries- Think of them like chapters.

2) These provide very few jumps per full charge, unlike Lead-Acid batteries in jump starters, and the lead-Acid battery in your ICE car. Lead-Acid have a higher capacity (higher Ah in Lead-Acid).

3) Make sure to charge this lithium jump starter every 30 days. It will lose charge continuously, especially during hot storage conditions. Lead Acid batteries are essentially unphased by summertime heat in respect to damage, however you will still lose charge during heat.

4) It's really best to carry this with you, to avoid keeping it in the car. Keep the cables portion in your car, and carry the battery portion in your pocket book.
OR, just buy a lead-acid jump starter for $40-$50 at walmart (700, 750 or 800amp for that price). You can get 1000amp for 65 and 1200amp for $100. Most of those include air compressors to fill up your tires (and auto-stops at the correct PSI that you set on the LCD, with one of the $40 models and many of the $100 models)


Expect to buy a new one every 2-3 years. A battery is considered dead once it drops to 90% capacity. You can still use it of course, however you won't reach the same voltage or Ah capacity.

Lithium batteries wear out each time you charge them. With the most wear & tear caused, the higher you charge it to 100%. The 1% from 99% to 100% causes >11x the wear as from say 60% to 61%. You can get a phone app like Accubattery, where you can play with the battery charge % to stop at, to see how much damage is caused to the battery when charging to specific percentages. It'll also show you your battery capacity- in mAh as well as % vs the original capacity.

Li-Po batteries stand up to heat significantly better than Lithium-Ion. But Li-Po are less energy dense, meaning that they're bigger and heavier than Li-Ion. Li-Po tends to be more costly than Li-Ion, and Li-Po has a higher risk of bursting into flames than Li-Ion (another worry about storing Lithium batteries in a car, especially the higher it's charged)

Would the 1000a one jump starter be good enough for Toyota Sienna or Honda Odyssey?

I have a Noco GB70 that I would use every once in a while over the years, but one day it just wouldn't charge at all anymore. There is a chip that can go bad and renders the unit useless even though battery in good shape after about 5 years. Found a guy in FL that repairs them, but not sure I want to incur the costs between shipping and his fee.

The GBX45 seems to be a newer model with USB C and can deliver power to charge laptops and tablets. in for a few of those.

On the chargers, what's a better all around model to charge car batteries, boat batteries, and the occasional smaller lawn mower starter type batteries? 5amp or 10 amp model?
