I thought the main advantage of lead acid or gel cell vs li-ion is cost, recharge cycle, and the ability to provide high amperage.

- samcheng 6y agoI'm not sure the cost advantage of lead acid still holds, especially with the e.g. shipping and disposal costs included.
- jimktrains2 6y agoThere is a reason we don't see lihion car batteries, or fork lift batteries as a default. (Yes, Tesla's are li-ion, but that's a scale where the weight savings begins to matter. Iirc those battery packs can't deliver peak amperage quickly or many times in their life, e.g. ludicrous mode.) Additionally, li-ion has non-neglegable disposal costs, so I don't think it's fair to count that solely again lead acid batteries.
- gsich 6y agoIn fork lifts it also acts as a counterbalance.
- t0mbstone 6y agoI don't understand how lead acid has an advantage in recharge cycles? My lithium batteries can be discharged and recharged over 1000 times before they wear out, and they hold a charge for ages. My UPS with lead acid batteries, however, is practically useless after a single full discharge, and the batteries have to be replaced practically every year.
- jimktrains2 6y agoSounds like a bad ups. Lead acid batteries can be discharged pretty far while still being rechargable..the same can't be said for lihion. Car batteries are lead acid/gel cell batteries. They last for years and can take a very large discharge while still being rechargable. Also, by cycle I meant a single vharge-discharge cycle can be more useful when larger amperage or more power is needed between charges.
