"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. " LOL , mine is 3 years old and I still use it to help start my construction equipment every so often… it shows no signs of degradation… I worry ZERO about how I take care of it , including keeping it charged , blah blah bland

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.

Quote from sleepyrx View quoted comment :
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)
Good write up, though it's my understanding that Lion has a greater fire danger than lipo. " The LiFePO4 batteries are the safest type of Lithium batteries as they will not overheat, and even if punctured they will not catch on fire. ... Due to the oxygen being bonded tightly to the molecule, there is no danger of the battery erupting into flames like there is with Lithium-Ion."

We have had these for 3 years, leave them in the car during the horrible winters we have in the midwest and during the heat in the summer. Charge them twice a year (before winter and before summer). They have been awesome. Haven't had any issues with jumping or them storing their charge. I would recommend going high than you need for a model, this way its compatible with larger vehicles down the road.

Debating on Genius 1 vs 5 for the winter. Seems the 5 could be good in a pinch (day before) which could be worth it

I'm going with the Genius5 basically for that reason—good to be able to get a dead 12v going pretty quickly, but also maintain the charge long term when not in use.

These things work great. A motorhome we used to have wouldn't start after not using it for a few weeks. The GB40 would start the Ford F-450 engine no problem.
