Portable 12v Battery Jump Starters

Gen 4 battery is in the engine compartment, so jump points shouldn't be a problem. Positive clamp on positive terminal on battery, negative clamp on a solid ground, usually a bolt in the engine compartment.

Just about any jump pack will do since there's no starter motor to drive, just some relays, etc.

The main thing is to ensure you don't reverse the polarity when jumping the Prius.

 

I've used our Jump-N-Carry 660 (JNC660) a fair number of times, pretty dependable. The older ones you had to guestimate how much to recharge them, but now their charger automatically shuts down when it's topped up. Good solid case, slim enough that it fits in third gen hatch underfloor tray, but that's not going to work for you with 2016. It might slip under a front seat ok.

Everybody's going to be chauvinistic towards what they've bought, myself included, lol. There are some very compact jumpstarters too, as long as it's for light duty like the Prius could be just fine.

 

I've used mine once on my 2009 Gen II, and numerous times on neighbours' vehicles (anything from Jeep Cherokee to divers Chevys), also I've used mine to recharge my SmartPhone and Tablet, and once or twice I've used the flash-light - details see threads passim (search is your friend!) Good luck! - hope this helps - Wil

 

Concur with the Clore Automotive choice... I have the Jump-N-Air model which also includes the air compressor for the tires... I got used to traveling in my Toyota 4Runner 4x4 which I've added dual batteries and a 1/3 hp air compressor for off roading.

Over the years I've had a battery that tested good at the start of the trip... going into failure in a remote area in South Dakota and.. picked up nails in two tires on another trip..

I feel naked going on long trips with out extra battery power and an air source for the tires.. Batteries and tires are the two most common failures that strand people . The Jump-N-Air goes in the Prius on any extended trip.

 

Sorry, where did I say "one" - I think I mentioned the model I bought last year from batterymart.com in one of the previous threads, and I'm sure I could find it by using the "search" function, but I've no need since I already have mine (and I bought a couple more for friends) and I didn't want to spoil the fun for you by removing the need for you doing your own search! (…it really is very simple!)

 

Since Prius just needs enough power to boot up the computer system, I am carrying this small lithium-ion battery pack. It is much lower weight than the lead-acid versions I have had, but I have not had to use it on the Prius yet. I carry a full sized spare, and that is already an extra 12 pounds or so, and I am tying to not weigh down the car unnecessarily with the emergency battery pack.

 

The 2016's battery looks to have regular (North American style) posts, and since it's in the engine compartment, maybe not even AGM??

 

could be. keep in mind the gen 4 12v is vastly improved over the past gen's. you may want to research the differences before investing a lot in past gen problem solvers.

 

How so? Won't it have to tolerate a much warmer environment?

 

Could someone with a 2016 maybe post a picture of the labels on their 12 volt battery?

 

they were able to put a much larger battery in. no idea how engine bay warmth affects the life of a typical car battery, but the prius 12v problems all stem from not being able to withstand a deep discharge without significant capacity loss.

 

I'm wondering if it's even an AGM. Either way, being in the engine bay would seem to negate the need to stay AGM, which should open the floodgates for reasonably priced replacement batteries.

 

Here is a photo of the GS-Yuasa 345LN1-MF battery in my 3 day old 2016 Prius. It appears to be a "Maintenance-Free", flooded cell, 45 AH lead acid battery.

IIRC 45Ah is a bigger capacity than the Gen 3 had.

 

That sounds like they don't fully understand, inserted a "boiler plate" response. With the 2016 there's no need to vent, and the posts look to be regular North American diameters.
