jump starter

A jump start, also called a boost, is a procedure of starting a motor vehicle (most commonly cars or trucks) that has a discharged battery. A temporary connection is made to the battery of another vehicle, or to some other external power source. The external supply of electricity recharges the disabled vehicle's battery and provides some of the power needed to crank the engine. Once the vehicle has been started, its normal charging system will recharge, so the auxiliary source can be removed. If the vehicle charging system is functional, leaving the engine running will restore the charge of the battery.
Motorists may carry jumper cables and other equipment in case of accidental discharge of the vehicle battery (for example, by headlights, interior lights or ignition switch left on while the engine is not running). Safe procedures for connecting and disconnecting cables are given in the vehicle manual.

    12 Volt battery going flat, no obvious reason.

    I have owned an MG4 X-Power for 2 years after previously owning an MG4 Trophy. In general I have been very pleased with both cars. But I had a flat 12V battery recently for no apparent reason. I eventually managed to open the driver’s door with the manual key. But fiddly but ok. Everything dead...

    Jump starter for electric car?

    The other day no key fobs worked but luckily the app came to the rescue and at least I could get in, but I know from reading some posts that the app failed them and they had to use the metal key and sort things from there with a power pack. I can find a shed load of these small starter packs...

    The new MGS6 12v battery is in the boot, is there easy access in case of 12v failure?

    I'm looking closely at the MGS6, I like it's size and quite a lot of extra kit over my S5, but one thing is concerning me is access to the 12v auxiliary battery placement in the boot, instead of under the bonnet in my S5, having had the dreaded 12v failure albeit my own fault and needing to set...

    12V battery drained in 48 hours whilst locked

    ADMIN may repost this elsewhere, but thought all EV owners need to guard against the 12v battery failing. I had the 12V battery failure on my MGS5 after no use for 48 hours, something had totally drained the battery, yet the car remained locked throughout. I ran a battery test, the battery was...

    Will Caliban start on Monday morning?

    Will Caliban start on Monday morning? Place your bets. So here I am in a hotel car park and my friend went in to sort everything out. She paid for five nights in advance (she got a good discount) but we can't take the car out during that time. I'm on 20% battery and concerned that the 12v won't...

    Jump Starter for my ZS EV Trophy Connect Long Range

    Hi Everyone. I've been reading that a useful accessory to keep in my car is a jump starter, since whilst the main traction battery might be fine and charged, if the 12V ancillary battery fails, I won't be going anywhere!! I'm sure I've seen recommendations somewhere on this Forum, but I can't...

    Lithium Jump Starter Warning

    After reading about the MG4 sometimes having a flat 12v battery I purchased a lithium jump starter to keep in the glove box just in case. I didn't want to pay for one of the big names but neither did I want a questionable Chinese knock off so I went for a Ring branded one from Amazon that was on...

    Jump Starter Power Pack

    Bought one of these a couple of days ago from Amazon: It has good reviews and is rated at 1500A peak so should be useful on both EV and ICE vehicles. Reduced by 29% at the moment so only £49.99 delivered with Prime (mine was delivered 6 hours after ordering!). Chances are I'll never need to...
