L-ion battery issue

[IJWS15]

Possibly should be in auto but….

Father (97) has a Volvo S90 and it has an assistance module fault so needs a battery. He ordered one on Amazon that claims to match - when I checked it was a Chinese seller. Battery arrived last week and I was asked to install it.

Original removed and looked the same as the replacement except original is labelled 8.0V 450mA 3.24Wh, replacement is labeled 3.8V charge limit 4.4V, nothing about capacity or rating.

He was all for fitting it but I dug my heels in and refused - visions of an S90 going up in flames when the new battery was connected to an 8v charging supply.

Have asked to return and ordered the proper voltage battery from a UK seller for half the price.

What would you have done?

I would not fit it

Unless he has a history of abusing the returns process, Amazon will probably refund with no problems/questions.

Enormous problem of course is that the genuine ones appear to be made in Israel. WTH I'd do if I needed one IHNI - hopefully find an OEM one which was actually the right spec.

you might think initially that its underpowered and iff it works ok it must be safe .... that is only part off the story and the highly dangerous bit is the charging circuit may turn it into a bomb as the charging rate will be around two to 3 times the level it can safely handle and the overcharging is where most fires start
