  1. Silicone spray along both vertical edges inside and out would be my first choice.

    Battery Spec

    The AA man was referring to another car, I think a 450h, which was having battery problems which he attributed to the owner's habit of leaving it unlocked. I was surprised at his figures for current as a trend in electronics for the past 10-20 years has been to reduce power consumption.

    Battery Spec

    You will have seen from my contribution that my 12v battery failed at just under 3 years ( first reg. December 2015). The owner for the first 2 years only used the car at weekends, covering 6,600 miles in just under 2 years and I, since purchasing in lasted Jan. 2018 have covered under 3,000 miles which is unusually low useage and might account for the premature battery failure. The AA man who came to my rescue said that, even when locked, the battery drain is 0.5 amps which will soon drain a battery. He said that when unlocked or with a window left open the drain is 4.5 amps. If those figures are true then the car can't be left unused for many days. As has been pointed out earlier, with traditional cars the driver gets an early warning of a tired battery from the sound effects when starting whereas with a hybrid it's simply go or no go. I shall take care to use the car more often from now on and leave my old Jazz on the drive more often.

    Had my car again fail to achieve "ready" condition. Again had the AA man out .....his meter said that the battery had failed. Jump started the car and took it to the nearest Lexus dealers who charged it and then agreed that the battery had failed. They loaned me a new NX300h for a day, fitted a new battery and washed and vacuumed the car ....all free of charge as the car was just under 3 years old. From now on I shall use this car more often (once or twice a week at a minimum). I have to say that I found the NX to be unrefined and lumbering and it made the IS feel like a true, nimble sports saloon when I drove it home.....why do people buy those SUVs?

    Are those compact jump starters rechargeable either from the mains or from the car? The photos don't appear to show any mains or other plug. I used to have a bigger sized mains rechargeable jump starter on my boat and carried it around for years, never needing it and eventually it's battery failed due to old age.

    Just had the problem of failing to achieve "ready" status. Tried connecting to my Jazz battery for 10 minutes ...no joy. Tried charging using my CTek charger ....wouldn't play ball. Called the AA who found that the 12 volt battery was displaying 9 volts. That might be why the CTek wouldn't play ball. He jump started the ICE and we watched the voltage rise eventually to 14 volts and then the ICE started slowly cycling on and off as the battery voltage rose and then fell. The AA man's instrument pronounced battery condition as "good" so he left and I let the car cycle on/off for 30 minutes as he recommended. Next day all was fine and we did about 2 hours daylight driving. Recommendation was to use the car for at least 30 minutes every week. I had left the car for 13 days as I had been doing lots of load carrying using the Jazz with its larger luggage space (seats down). I will now make sure that I use the Lexus at least once a week but it does raise the point, already mentioned, of for example leaving the car at the airport for 2 weeks while on holiday. My old Jag. had the same battery for 15 years, was quite often used less than once a week, and ALWAYS started first time. I only joined the AA just a year ago as part of the deal when I transferred my car insurance to them ...better keep the membership going.
  7. A friend of mine always used to include the under bonnet area in his car washing routine ....even to the extent of rinsing with the hose. Personally I'd never risk that but I do wipe around with a cloth to remove dust etc.

    I don't think that the dog food comparison is a valid one. There are some very poor quality cheap dog foods made using very dubious ingredients. They are favoured by owners of habitually greedy dogs like labradors. Even if you buy expensive food you can get caught out as I did when our dog developed pancreatitis due to his dried food, which was prepared from human consumption grade chicken, virgin olive oil and rice, turned out to have too high a fat content. Given the magnitude of veterinary bills it's wise to check these things quite apart from the dog's welfare. Petrol, on the other hand, all has to meet quite narrow specifications and although I believe that some supermarket own brands barely meet additive specs., 95 octane of a big name brand ( I always favour Shell) will be fine for an IS300h which isn't that highly tuned at 72 bhp/ litre. I owned a much loved Jaguar XJ8 for 16 years and always used 95 with never a hint of trouble from the engine.

    Finally I realise that as that motor generator charges the traction battery then ,when starting the ICE it's bound to be powered by the same battery and the 12 v battery isn't involved. Been rather slow in catching on!

    I'm aware that any starter motor takes very little energy in terms of amp hours but does the energy required for starting an IS300h come from the traction battery albeit via a dc to dc converter or is it direct from the traction battery?

    I'm intrigued to see that the Yuasa battery says recommended charge rate 3 amps. Elsewhere I recall reading 4.5 amps. Either seems ridiculously low for in-vehicle charging - you'd need to drive a long way to recharge a depleted battery.
  12. I own a 1958 MGA sports car which has two 6 volt batteries in series to power the 12 v system. After restoration between 1981 and 1983 the first pair of batteries lasted 11 years and the second pair 10 years. After that I started having trouble with batteries which was eventually cured by converting to using a single 12 v battery. I believe that the problem was that the more recent 6 v batteries were intended for use in golf buggies and so were deep cycle and couldn't supply enough current for cold starts. I expect that true car type 6 v batteries are still obtainable but it's a possible pitfall if choosing deep cycle batteries. So called leisure batteries provide enough CCA (cold cranking amps) and have reasonable deep cycling ability and I always used them on my boat, finding that they lasted about 10 years.
  13. That oil certainly doesn't look clean enough. Possibly they didn't leave it draining for long enough or drained it when cold. I assume that the level shown is after the car has been standing for an hour or more .... if so then that level is too low. I used to do all my own car maintenance but apart from my tractor I leave it to garages now....either my local or else the appropriate dealer , and I've never seen evidence of such shoddy work.
  14. Given that the seats reportedly met or exceeded Federal requirements I'm surprised at the verdict. What, then, is the point of having these design/performance requirements?
  15. I seem to recall reading that it's connected via a DC to DC converter to reduce the voltage from 230 to a suitable level.
