Hi Gang,
Cold weather has finally come to the west. As always cold tends to
bring out the worst in a battery. This has enabled me to weed out the
2 weakest batteries from the 72v pack that powers the Ninja.
One was my lowest voltage battery that appears at one time to have had
a reversed cell (mostly speculation on my part I admit). I believe
that this battery is not just weak, but seriously in trouble. I
believe that its future is the recycling bin somewhere. Any good
disposal suggestions?
Take it back to your battery supplier for recycling.
The highest voltage battery in my pack has also been removed. I
observed it during normal discharge conditions and found its voltage
dropped off more quickly than its peers. When I removed it I weighed
it and found it almost a pound less than it neighbors leading me to
conclude that it is missing some electrolyte (or whatever they
actually use in an AGM). It appears that at one time someone used this
battery to power the lights on the cycle. In any case I would like to
reuse this battery (as a starting battery in my ICE) if I can find a
way to get in more electrolyte and it returns to a more normal
charge/discharge pattern. Is this a good idea? The ICE is old and I'd
be happy with a 3 yr life or less from the YT in its new role as a
starting bat.
Can you advise me on how best to breath life into a YT that needs
fluid? I don't know what to buy or how to get it past the vent valves.
As always any advice that you have is appreciated.
Advice from our electric vehicle club www.evco.ca includes getting rid
of remaining batteries in a broken set (where a couple of existing
batteries have to be retired) by selling the remainder on the used
market and buying a complete new set. The new set must be carefully
matched in model, date of manufacture and even if possible sequential
serial numbers. When ordering a new set you can specify this requirement
with your supplier.
A carefully matched set of batteries will give superior performance.
