Comparing Batteries ?

on 07/03/2011, the_constructor supposed :

I would suggest they are pretty much of a muchness. Just ensure the one you get is designed for deep cycle.

Yausa or Varta would be my first choice

Lucas? ? Back in the 70's, Lucas decided to diversify its product line and began manufacturing vacuum cleaners. It was the only product they offered which did not suck.

I haven't read any of the info within the pages of this link but, it may be of use...

In article , Harry Bloomfield scribeth thus

Over time we have used quite a few of these for differing applications standby power motors etc. Yausa seem to have been the best of the bunch:)...

Car use and motor traction use are a bit different . The NP would be the best person to ask re batteries he's very knowledgeable on those...

Thanks to all who have helped so far.

Next question.

AGM, GEL or Superior GEL.?

Hi Jim

As others have suggested - and FWIW, I'd go for Yausa too. My mother-in-law needed some new batteries in her 4-wheeled mobility scooter and that was the make everyone seemed to say was the most reliable.

Just a personal thing - I'd be very wary of buying them off eBay. Better to check around local battery suppliers and pay a bit more - that way, if the batteries don't perform the way they should, you can get them to sort out the problem. I've heard some sad tales of apparent 'bargains' on auction sites. Others may have wonderful tales to tell, but with something as critical as a mobility scooter or wheelchair, you need reliability above all else.

I found the Disability Living Foundation very helpful

Good luck!

Any of those would work fine. Where have you found the best prices on these so far?

A little off topic as most powered wheelchair users use a sort of fleece, but how do electric vehicle users stay warm?

As efficiency goes up there is no room for "comfortable" heat generation so do the owners of that new one million pound Rolls Royce have to dress up in thermals, or generate a kW or so of heating from PP3,s?

Electric heaters. No, really, they just have to top up the waste heat=20 from the motor with juice from the battery.

--=20 Skipweasel - never knowingly understood.

Waste heat?

There is little waste in a modern motor. I would hazard a guess that most of the heat loss was via the tyres and air compression.

HN

Electric heaters run from the battery pile. That's why they rarely give the range advertised by the maker. Using lights, indicators, radio, wipers and most of all demisters and heaters reduce range enormously.

Don't worry. Many, many other people sre as slow as you in spotting one of the major flaws in EVs for the UK climate.
