consumers prefer low weight - manufacturers give them lower weight by reducing the thickness of the lamination and the battery's longevity.Can't help feeling battery technology has in some ways gone backwards.
NiCads lasted many years on e-bikes too. It's all about cell density/capacity. A NiCad D cell was typically 5ah, the successor NiMh D cells 10ah but much shorter lived.Bit OT I know but I have a small portable transistor radio on the shelf next to me, it holds two Sanyo Ni-Cads.
Still working with the same batteries ..... 30 years on !
Last charged about 3 yrs ago and just checked again, PWO. Can't help feeling battery technology has in some ways gone backwards. Imagine a Li-ion cell lasting 30 years
That's a good voltage at which to recharge. Regularly running your battery down to near empty is recognised as effecting capacity over time. As nealh has said, 35E's are decent cells, so as long as you avoid prolonged high power use, then they should last well.I cycled home and back to work this morning without charging the battery,so I'm well pleased.I had 49.6 volts left on the battery.
