I changed my OEM battery for the Bosch S4 E08 EFB. Operates great and Alright priced. I would watch out with switching to your AGM battery. The handbook is pretty obvious on the subject and volvo's are pretty picky.
Link the charger good bring on the battery favourable terminal, and the charger damaging to any suited earth level in the chassis. There's a little earth guide connected to a bolt on the nearside strut mount turret around on the battery on my vehicle - I use that.
So the vehicle sits at four/5ths billed and with a little although not insignificant battery drain from the onboard ECUs, which nonetheless draw some electrical power, even in rest method (parked and locked auto).
But I do not know why so A lot of people get so worried about begin/cease not Doing the job. I programmed mine out, Which satisfies me great
Add to quotation Only clearly show this person #one · Mar 23, 2024 My automobile will not likely commence. The starter motor struggles to turn more than, but there is no warning to the sprint of a reduced battery voltage problem. It jumps commences just good. All of the electronics turn on, and also the lights are vibrant (LED headlights).
Charging the primary battery with an off-motor vehicle charge also costs the auxiliary battery, but you have to hook up the adverse charger cable to an earth position faraway from the battery - not the destructive battery terminal - to prevent puzzling the battery sensor that may lead to it to shut down start off/stop as well as other units.
Add to quote Only present this consumer #4 · Sep one, 2024 The vehicle will generally clearly show a small battery warning and switching off message When the infotainment method is working along with the motor is off, for 2 good reasons. For starters, the BMS procedure maintains the battery in a lower than totally charged condition or close to 80% SOC, to supply an overhead lifepo4 lithium battery to keep the demand created via the clever alternator when the vehicle is driven. Additionally, it seeks to make certain that the battery has adequate cost obtainable in order to restart the engine, both from rest or after a quit/begin occasion. So there is a fairly narrow band in between the normal state of battery charge and the level at which the warning is generated, less than with older cars and trucks with dumb charging units that aimed to maintain the battery totally charged and wasted subsequent alternator output (the dumb traditional alternators couldn't be switched off when driving, compared with the clever style, throwing away gasoline and raising emissions).
"So you're able to see it’s calculating that it could possibly't operate for long with out risking getting to very low too start off the engine.
Add to quote Only clearly show this user #7 · Nov 9, 2021 I have also completed it final year. Just choose your time and energy And do not hurry when eliminating the filter box assy as you may perhaps crack the enamel on the pipe coming from the recirculation (proper side from the box).
Also there is a great probability that BMS will reset itself just by taking away the signal direct from the adverse pole in the battery (it is the small black cable). BMS ought to be reset to recalibrate and find the new battery equipped
or they get fitted to cars and trucks that dont get through the future mot. the industry normally is geared up to produce crap to unsuspecting motorists. right up until tackled, the oem or seller route is a smart option for the majority
To be trustworthy I always switched get started/end off anyway, but it surely niggles me that it is not there if I want to use, daft I am aware, but to me if that perform is just not Doing work then something need to be halting it from Performing in the battery / BMS ?
So I chose to reset the BMS using the video clip Guidelines previously mentioned, hey presto, Commence/End grew to become offered quickly along with the media program was nevertheless on right after more than 10 minutes, so I guess thats a result
So it turned out, the secondary battery from the front bumper was stuffed. This is backup and begin/cease battery. It gave about 5 yrs existence, but here is the amusing element:
