Visitors of BatteryUniversity.com frequently ask: “Can NiCd can be replaced with NiMH?” In theory, this should be possible as both chemistries have the same cell voltage, but full-charge detection and trickle charge are the issues. NiMH uses a more refined charge algorithm than NiCd(See BU-408: Charging Nickel-metal-hydride) A modern NiMH charger can charge both NiMH and NiCd; the old NiCd charger could overcharge NiMH by not properly detecting the full-charge state and applying a trickle charge that is too high. Each chemistry requires its own charger.
Fortunately, our batteries tend to last an exceptionally long time. That’s because we use the latest absorbent glass mat technology in all of our products, which makes them less susceptible to sulfation and leaks.
2. Replenishment: For the electric vehicle lithium battery, the battery is replenished with water for about 4 months, which can prolong the service life of the battery and extend the average time to more than 3 months. It should be noted that after each replenishment, the battery is in an overcharged state to change the battery from a "pre-lean liquid" to a "lean liquid" state, and this over-charging is beneficial to increase the battery capacity.
I tried this over a year ago on my wife’s 2014 Subaru Crosstrek. We finished out the Winter of 2018-2019 and 2019-2020 without any problems. What do you have to say about the practice of applying a thin coat of dielectric grease to the battery posts? I really hope that you have an authoritative and definitive answer to this, because it is so controversial. I am pretty meticulous when I change a battery, as compared to some of the you tube videos.

iPhone batteries are made from li-on cells. It’s not possible to repair the battery, only replacement.
Hi Dave. It is, to the best of my knowledge. It's an antique, found in an old hardware store. Good luck with the pallets - there's nothing I hate more than breaking apart those stupid pallets, lol. ~ karen!
