Nah sales persons job is to present you with the most accurate information and let you choose whether a lead acid battery or a lithium battery is right for you.
A good salesperson is just a consultant to assist you in getting and enjoying the best solution possible.
The conclusion is not clear cut and the answers will be different for different customers
Here's the sort of things I am advising customers to weigh up when they talk to me.
- Yes for racers with a good budget the weight savings (Up to 4kg) make ltihium batteries a done deal. How else do you loose 4 kgs for such a small price premium....you can't.
- Yes Lithium batteries are more reliable by a factor of several times. (Although it's very early days yet our user poll shows that around 14% of lead batteries fail in the first two years and 25% have failed by the end of the third year. If that was the failure rate of a home appliance somebody would be getting nailed on Campbell Live! or having to answer some very hard questions from the Ministry of Consumer Affairs...perhaps they should be.
- Even the worst of lithium batteries have failure rates well under a third of those failure rates, and the best are proving to have failure rates well under 1% for the first two years.
- Consider also that because a lithium battery has very low self discharge rate and most commuters don't run total loss systems, and this might be another cost benefit to owning a lithium battery.
- Factor in the cost of a smart tender if you are an infrequent rider, (which will cost nearly as much as your lead acid battery) and the annual cost of ownership starts to swing to lithium batteries.
- But of course many customers will already have a smart lead acid battery tender. So this is a cost they have already met.
- Scan the internet for actual real world incidents (rather than the theoretical ones) and the damage caused to the bike... and the risks of lead acid batteries and Lithium batteries are pretty similar.
- You can mitigate the MOST serious of these risks (the one that creates the most dangerous risk - the short circuit) by buying a lithium battery with the correct type and correctly rated fuse built into it.
- But you also have to consider that most people change bikes every three years then the very high failure rates (25% within three years) of lead acid batteries becomes more acceptable (because the battery becomes someone else problem) Unless you can swap your lithium battery from one bike to another, you could lose on the deal when the next owner gets your reliable long life lithium battery and you may get a bike with an old lead acid battery.
Sales consultants need to give you the best information so that you can make an informed decision and then sell you the technology you choose.
If we haven't got what you need (maybe a lead acid battery is best for you) then we need to accept and acknowledge that you need to purchase from another supplier.
